In Defense of Yeshiva University Parshas Pekudei

This past Thursday night, a rabbi friend of mine texted me, “Watcha got?”

This is what rabbis do when they need an inspiring story, a new angle, or just to get those drasha-juices flowing.

I replied that I am thinking of talking about YU. I was referring to the news that this past week, how Yeshiva University came to an agreement with a group of students who wanted to open an LGBT club in the college. This controversy has been raging on for years in and out of court. There are legal issues at play as the college is officially a public institution, and of course, there are matters of Halacha and Hashkafah that have to be addressed.

My friend surprised me by saying that he was also thinking about talking about YU. “Really?’ I wrote back. My friend’s not the controversial type. He said, “Yes. But it has nothing to do with the club. My message is that no one should ever go to Yeshiva University, club or no club.”

The particular controversy around this club in YU is a very important one, one that I would like to revisit at a later time. Sorry, not today. Today, I’d like to reply my colleague and good friend, who will not be named, who, like many people before him, have suggested that Yeshiva University is intrinsically flawed, that one cannot have an institution that is both a yeshiva and a college, that the merging of the holy and the mundane is a grave mistake.

For starters, let me get this out of the way, I did not go to YU. I went to Ner Yisroel so I have no skin in this game. (Once we’re on the topic of where I did not go, I also did not go to any Chabad yeshivas despite my little beard and my tzitzis hanging out. I get that question a lot. Now that we got that out of the way…)

Yeshiva University was established in 1886. But the controversy around secular studies goes back almost 1000 years. It came to a head in the times of the Rambam, Maimonides, who famously incorporated Aristotelian thought into his worldview. Perhaps more accurately, Aristotelian though guided his worldview. One of the Rambam’s most famous works was Moreh Nevuchim in which he addressed every possible critique against the Torah, using what some would describe as secular logic.

In his lifetime, most people disagreed quietly, but after he died, the controversy exploded. His opponents were concerned that his openness to secular knowledge would suck people into a world that rejected G-d and the Torah. Ultimately, some of his opponents turned to the local authorities telling them that the Rambam’s book, Moreh Nevuchim, was a threat to all religions which led to one of the most tragic moments in Jewish history. In 1232, encouraged by enemies of the Rambam, a group of Dominican monks went through France, confiscated all the copies of Moreh Nevuchim they could get their hands on, and burned them in a public square.

In 1305, the Rashba, the leading Torah scholars of that time, tried to make a compromise between the opponents of learning secular studies and those who embraced it. He suggested that one can learn secular philosophy but only after the age of 25. His attempt at compromise went nowhere. Each side dug in even deeper.

On one side you had those who believed that a deeper knowledge of philosophy, of science, of history, broadens us. By extension, this group of Torah leaders believed that we should embrace and grapple with the world around us. On the other side, there were those who believed that any engagement in the world around us posed too many risks. They believed that worldviews that do not align to the Torah will draw us away from G-d and will distort our understanding of the Torah. The Vilna Gaon, after disagreeing with a ruling of the Rambam, famously quipped: “The Rambam’s engagement in philosophy caused him to err.” (Yoreh Deah, 179:6:3)

On Thursday night, I had the great joy of seeing one of my Rebbeim from Kerem B’Yavneh, Rav Mendel Blachman who was visiting Baltimore. He is a towering individual who I credit in so many ways for anything I have learned and accomplished in my life. One specific story is worth sharing in this context:

One Shabbos, our yeshiva, Kerem B’Yavneh, was visited by Rav Hershel Schachter, Rosh Yeshiva of Yeshiva University. After Friday night dinner there was a Q and A session. One of my good friends, a bright guy with zero tact, got up to ask a question. “Rav Schachter, does it bother you that virtually all the Gedolim, all the great Torah scholars of the day, disagree with your worldview?” Among other things, my friend was referring to Rav Schachter leading Yeshiva University, a place where secular studies are explored side by side with Torah study, he was referring to Rav Schachter’s unabashed Zionism. These are positions that many of the great Torah leaders of our time disagree with. Rav Schachter being the humble person that he is, did not answer the question.

Sunday morning, my rebbi, Rav Blachman, came into our class. He opened the Gemara we were learning and then he closed it. Instead of delivering his regular Talmud class, he spent the next hour railing on those who believe there is only one hashkafah, one approach to understanding how a Torah Jew, is supposed to live their life. That is not the Jewish way. There has always been divergent views within Torah Judaism. And yes, there have been views beyond the pale; the Sadducees, the Karites , the Sabbateans, other denominations of Judaism and others. But within Torah Judaism, within a worldview that subscribes to absolute fidelity to the Torah and to the Sages, there has always been more than one way.

There are exceptions, there are Mitzvos that our Sages decided cannot have divergent views. Mitzvos like Kiddush Hachodesh, the sanctification of the new moon, the Jewish calendar. Imagine a world in which there were two views on what day Pesach starts, that would be a disaster. Such a debate would rip us apart as a people and that’s something we cannot allow. The Gemara shares a story in which Rabban Gamliel forced his colleague Rav Yehoshua to travel on the day Rav Yehoshua thought it was supposed to be Yom Kippur based on his interpretation because two calendars would upend Jewish unity. But this story is the exception! For the most part, honest, Torah-driven debate, was the rule. And that’s more than okay. It’s necessary. G-d created us with different temperaments, with different proclivities. Inasmuch as we have different tastes, there are different flavors to Judaism.

Rav Blachman concluded, not only was the question rude, it was wrong. Find yourself a Gadol, find yourself a great Torah scholar (not some guy with the title rabbi before his name who writes well on social media). Find someone who is immersed in Torah, and if his Torah worldview speaks to you, if it resonates with you, follow him. And stop looking over your shoulder, stop worrying about the fact that this or that great Torah scholar disagrees. Find your Torah leader and follow your own path.

Centrist Orthodoxy or Modern Orthodoxy or whatever you want to call it has a complex. Those who subscribe to it are constantly looking over their shoulder, and that’s ridiculous.

Is Rav Yosef Soloveitchik not worthy of following? Is Rav Avraham Yitzchak Kook not worthy of following?

In a world in which there are great rabbis telling people not to support the IDF and there are other great rabbis arguing that IDF soldiers are the holiest people on the planet, I don’t know about you, but that second group is far more compelling to me.

In a world in which all of us, whether you live in Teaneck or in Lakewood, is engaged in the secular world around us, and there are great rabbis pretending the world around us does not exist and there are great rabbis grappling with how to engage, what to keep and what to throw away, I don’t know about you, but that second group is far more compelling.

So no, Yeshiva University is not a bad place. If you are deciding between a college in which there is no Torah learning and a yeshiva college in which there is; if you are deciding between a college where the rate of attrition is sky-high, where a significant percentage of Jewish boys and girls are not remaining committed to their upbringing, which is virtually every secular college, and Yeshiva University, where yes, there may be a club that we will one day discuss, but for the most part, the students are able to live fully immersed Torah lives, the decision is clear. Yeshiva University is a gift.

Yes, our community needs to strengthen itself in its Torah observance. Yes, our community needs to elevate the way we pray, and it needs to step up the level of Torah learning. But do not be embarrassed. Do not be afraid. To walk in the footsteps of the Rambam, of the Ramchal, of Rav Kook, of Rav Soloveitchik, admas kodesh hu, we are on holy ground.

***

We just said the words, Chazak, Chazak, V’nis’chazeik, as we completed the book of Shemos. The Sefer Hamanhig points out that those words, “Chazak, be strong!” were first said to Yehoshua. This is not a coincidence. As opposed to his teacher, Moshe, who led the Jewish People in the desert, sequestered away from the distractions of the world, Yehoshua led the Jewish People in battle, he led the Jewish People into a life of commerce, into a life of worldly engagement, a life that we, our community, believes in. It takes strength to live a life of worldly engagement. So let’s be strong. Chazak, Chazak, V’nis’chazeik.

Kashering the Kitchen for Pesach

Sink: One cannot kasher their sink unless it is made of stainless steel. 1) Clean sink thoroughly. 2) Do not use hot water in the sink for 24 hours prior to kashering. 3) Boil water. 3) Pour boiling water directly on every surface of one’s sink. Allowing the water to flow from one side of the sink to another does not suffice.

Refrigerator: All shelves and surfaces should be cleaned thoroughly. If it is difficult to clean shelve (due to ridges etc.) or it is an area which food touches directly (like a vegetable/fruit drawer) then one must line that area. Otherwise, no lining is necessary.

Any chameitz food that needs refrigeration should ideally be finished before Pesach. If that is not practical, one must place the food in a specific area and cover it in a way that is not so easy to access the food.

One should clean the entire stove top area thoroughly. The way to kasher the burners is as follows:

Electric – The burners should be lit until they glow red.

Gas – Turn the stove top on for five minutes. The grates should be placed inside the oven with the oven at a high heat for forty minutes. 

In the stove tops listed above, one should either lightly blow-torch the area between the burners or the area must be covered (foil is a safe cover to use).

Glass top – One should put the burners on high and pour hot water over the other areas. Even after kashering, if one has a glass top stove, one should not place any food or pots in between the burners over Pesach.

Whether one can properly kasher microwaves and dishwashers for Pesach are a matter of much debate. I would therefore highly discourage doing so. There are those who rule leniently in this matter and therefore if someone feels like they need to have their microwave or dishwasher, please follow up with me via email/ call for the details as to how to do so.

Kashering ovens for Pesach –

In a regular oven one must clean all surfaces (including thermostat, window, corners, door edges, etc.). One should use a caustic cleaner such as Easy-Off to remove spots that are difficult to remove. If one uses Easy-Off twice and the spot still does not come off one need not worry about it. After cleaning the oven and racks thoroughly one should set the oven to its highest setting for 40 minutes. The broiler pan cannot be kashered but should still be cleaned thoroughly or removed.

As with all kashering the oven may not be used for 24 hours prior to kashering.

In a self clean oven one must remove all visible food and set oven for self-clean with racks inside. When kashering through self lean one need not wait 24 hours prior. 

 

When Erev Pesach falls out on Shabbos (2025)

The search for Chametz is done on Thursday night after nightfall (8:21 PM). The burning of chametz is done Friday by 12:02 PM (Baltimore, MD). 

Although you may eat chametz until Shabbos morning at 10:56 AM, the sale of chametz takes place on Friday morning. Any chametz you plan on eating on Friday and Shabbos morning should be placed apart from the chametz that will be sold. 

Shabbos meals should be completely Kosher for Pesach with the exception of the bread (explained below). 

Technically, you can set aside an entire chametz meal but due to the logistical challenges it is not recommended. 

One should set aside two pitas or soft rolls that do not generate substantial crumbs for every Shabbos meal. They can be eaten at the table if one is using disposable utensils and a plastic sheet. Alternatively, one may eat the bread outside on their porch and then come back inside to eat the rest of the meal. 

There are those who allow eating Matza on Friday night, many do not. All agree Matza cannot be eaten Shabbos day. 

The bread must be eaten before 10:56 AM. The meal may continue afterward. 

In order to enable eating challah before this, most shuls start davening on Shabbos morning earlier than usual.  

One is obligated to have Lechem Mishna, double bread, at every Shabbos meal, to commemorate the double portion of man that fell every Friday while the Jewish People traveled in the desert. It is meant to remind us that G-d takes care of all our needs. 

According to some opinions, one may use Egg Matzah for Lechem Mishnah. If one relies on this opinion, Shabbos meals need not be eaten early. One should not eat egg matzah on Pesach. 

Some are of the opinion that egg matzah is chametz and therefore can be eaten on Erev Pesach as it is not matzah but cannot be eaten after the morning (Rav Moshe Feinstein). Others (Aruch Hashulchan) are of the opinion that it is not matzah or chametz and therefore can be eaten all day. Others, due to the uncertainty around egg matzah, do not eat it on Erev Pesach/ Pesach. And others allow eating it on Erev Pesach alone.  

 Seudah Shlishi – One is obligated to have three meals every Shabbos. There are three ways to do so on Erev Pesach that falls out on Shabbos.

  1. Start the first meal really early. Finish the meal and take a little break by reading a short book, or going on a short walk. Then return and eat the third meal with two rolls of bread. Of course this must be eaten before 10:56 AM.
  2. There is an opinion that one can fulfill the obligation of eating the third meal with fruit, meat, or fish. One can then eat this meal at any point during the day but should not eat too late so they have an appetite for the seder.
  3. There is an opinion recorded by the Magen Avraham that one can fulfill their obligation by learning Torah. This is not a conventional view. Nonetheless, one can rely on it if need be.

Leftover bread should be broken up and flushed down the toilet before 12:02 PM. 

It cannot be placed with the other chametz as that chametz has been sold already. Placing it in the garbage is not sufficient. 

At 12:02 PM all chametz becomes muktzah and cannot be handled. One should say Kol Chamira (found in a siddur in the Pesach section), nullifying any remaining chametz, before this time. 

One may not start preparing for the Seder on Shabbos. One may only start after Shabbos concludes at 8:23. 

Before beginning to do anything for Pesach, one should say, Baruch hamavdil bein kodesh l’kodesh/ daven Maariv. 

One lights Yom Tov candles from a pre-existing flame. 

*Pro Tip: Set your dining room table for the Seder on Friday. Eat the Shabbos meal at a kitchen table. This enables you to start your Pesach Seder as soon as Shabbos ends.*

Laws of Pesach

Pesach is less than thirty days away! Are you ready?

  • It is not only forbidden to eat chameitz, there is also an obligation to get rid of all chameitz that is in one’s possession.

Biblically, one can relinquish ownership of chameitz that is in one’s possession and that would take care of the issue of owning chameitz. However, our sages were concerned that if one would have chameitz that is sitting around in one’s home they would inadvertently eat it. They therefore required one to remove all chameitz from one’s home. 

It therefore follows that if one relinquishes ownership of the chameitz in their home they do not need to remove chameitz from locations that are very difficult to reach since there is no concern that one will inadvertently eat the chameitz there. Additionally, the rabbis concern was only about substantive food items, like a cookie. One need not worry about crumbs. For example, there is no obligation to move a fridge to remove chameitz from behind the fridge. (This is not the same as the prohibition against eating chameitz, which one would violate by even eating a crumb. For this reason, cleaning in the cooking/ dining area is different than cleaning anywhere else.)

We are only obligated to search for chameitz in places that we have reason to assume that it will be found. This makes Pesach cleaning very subjective. If for example, one has a strict policy of ‘no food outside of the kitchen and dining area’ then they only need to look for chameitz in those locations. If one has young children then typically every area of the house potentially has chameitz.

Once we relinquish ownership of our chameitz, there is no Biblical prohibition of having chameitz in the house. The Rabbis were concerned that if chameitz was sitting around one would absentmindedly eat it. That being said, when one is cleaning for Pesach there is no need to look for crumbs. Since we either sell our chameitz and whatever is not sold, we relinquish ownership to, we therefore do not need to worry about insubstantial items like crumbs and the like. The one exception to this is the kitchen which we will discuss shortly. 

Books – Although one sometimes eats while reading books and therefore there is reason to assume that crumbs have fallen in between the pages one need not clean out every book they own. However, due to this concern the custom is not to bring books to one’s table during Pesach. Benchers that are used during the year should not be used on Pesach and should be put away with the chameitz that is sold.

Kitchen/ Dining Room Table – One should clean very well. If there are hard to reach places, the area should be sprayed with a harsh cleaner. The custom is to cover the table with a water-resistant cover such as a plastic sheet. It should be thick enough that it shouldn’t tear during Pesach.

Tablecloths/ dishtowels – The custom is to use ones that are designated for Pesach use. If this is difficult one can wash the tablecloths/ dishtowels and use the same ones they use year-round.

As mentioned in the previous days, the primary concern of chameitz lying around one’s home is because one may eat the chameitz food. This obviously is not a concern when it comes to crumbs. Therefore, there is no need to drive oneself crazy to find every crumb in one’s home. If one does not have young children and there is no concern about food being hidden in all sorts of places then one should not be breaking a sweat when cleaning for chameitz.

However, when it comes to the kitchen there is an additional concern of eating chameitz. It is forbidden to eat even a drop of chameitz. That being the case, if a crumb of chameitz is left on one’s kitchen floor and a piece of food falls onto the floor on Pesach, the chameitz can get attached to the food and become forbidden to eat. Therefore it is imperative to meticulously clean one’s kitchen.

In addition, anything that came into contact of hot chameitz during the year retains a chameitz status and if it comes into contact with hot food on Pesach can make the food chameitz and forbidden to be eaten on Pesach. We therefore must purge all appliances and surfaces before Pesach to remove any chameitz from within them. The laws of purging appliances, otherwise known as kashering, are discussed in a different post. 

Refrigerator: All shelves and surfaces should be cleaned thoroughly. If it is difficult to clean shelve (due to ridges etc.) or it is an area which food touches directly (like a vegetable/fruit drawer) then one must line that area. Otherwise, no lining is necessary.

Any chameitz food that needs refrigeration should ideally be finished before Pesach. If that is not practical, one must place the food in a specific area and cover it in a way that is not so easy to access the food.

Soaps, Shampoos, and Lipstick

Although there are those who are stringent not to, it is permitted to use shampoos and soaps that are made with chameitz materials. (Owning these items is not a problem because it is not fit for consumption).

Ideally, anything that will come into contact with one’s mouth should not have chameitz, even though it is not fit for consumption. Therefore, items like toothpaste, lipstick, chap-stick, and similar products, should be chameitz-free. Kashrut agencies such as OU and Star-K have comprehensive lists on their websites and in print.

Cupboard Shelves, and Towels

One need not line cupboard shelves or drawers with shelving paper. Since they do not come into contact with hot food the only concern is cleaning the area out from any Chameitz.

One may use towels and table-cloths from year round on Pesach as long they are washed in hot water and soap before Pesach.

I want to emphasize that I am writing what is necessary by law. Jewish People from time immemorial have cleaned for Pesach with extra stringencies and it is a beautiful testimony to our ancestor’s commitment to G-d. I would advise that if one has a custom that is a stringency one should treasure it and hold on to it. If for some reason it becomes difficult to maintain, it should be weighed seriously before being discarded.

Pills

If something is inedible we do not treat it as Chameitz. However, if one puts that item in their mouth to digest it the Poskim debate if in doing so one gives the item the status of food. In that light I would recommend the following:

Medicine: Bitter or tasteless tablets, capsules, or liquids may be taken on Pesach even though they have chameitz ingredients. (If the medicine taken is in the form of pleasant tasting tablets or liquids an alternative should be found. If none is available, check in with a rabbi before discontinuing use.)

Vitamins: Ideally, a chameitz-free vitamin should be used. If none are available, then as long as the vitamin is bitter tasting or tasteless and prescribed by a doctor, the vitamins may be taken on Pesach.

Eye drops, ear drops, nose drops, and throat sprays do not need to be chameitz free.

Miscellaneous: Don’t Need to be Kosher for Pesach

A few more things that do and do not need to be kosher for Pesach: Paper-ware and plastic-ware do not need to be certified as kosher for Pesach. (However, some do not use paper plates unless it is certified to be Kosher for Pesach. This is due to the fact that corn starch is used in the plate.)

Dish soap, strictly speaking, does not need to be kosher for Pesach but the prevalent custom is to use only kosher for Pesach dish soap.

Liquid cosmetics that contain alcohol, wheatgerm, or vitamin E, is a matter of debate. One may rely on those that permit using perfume, cologne, shaving lotion etc. on Pesach.

One last thing, although not typically eaten by humans but still must be kosher for pesach is pet food. (Pets may be fed food with kitniyot.)

Selling Chameitz

The Talmud relates a story of a man travelling on a boat with chameitz. Realizing that he would be stuck on a boat over Pesach with a large quantity of chameitz, he decided to sell it to a non-Jew who was travelling with him. After Pesach, he bought the chameitz back. Over time, it was common practice for businesses that dealt with large quantities of chameitz would sell their chameitz to a local non-Jew to save them from incurring a large financial loss. Nowadays, in an age of stockpiling, it would be a substantial loss for any of us to just get rid of all chameitz products before Pesach (especially after Purim!), we therefore sell our chameitz to a non-Jew for the duration of Pesach.

The sale itself is rather complex due to the fact that there is no transfer of the physical items being sold. It is therefore customary to appoint a competent rabbi as one’s agent to sell their chameitz.

All chameitz food that is being sold must be placed in an enclosed area. If one could place it in a separate room that is most ideal. If not, cover in a way that makes it difficult to access. If food is in a cupboard one should tape the cupboard down.

We do not sell our pots and pans that have been used for chameitz The reason for this is that if we were to sell a non-Jew our dishes and buy them back after Pesach, we would have to tovel all of those items that we just bought from a non-Jew.

If one will be in a time zone that is different than the time zone that the sale will take place in, one should discuss this with their rabbi. There are some complications with such a sale. For example, if one is in California, where they are three hours later than us in Baltimore, and the rabbi buys back the chameitz immediately after Pesach, the individual who is in California will be in possession of chameitz for the last few hours of Pesach.

This year (2025), the chameitz will be sold on Friday morning. One should put aside any chameitz food they plan on eating afterwards.

Searching for Chameitz

One must search all their property on the night before Pesach. This includes one’s car and any office space which is owned or rented. If it is very inconvenient to check one’s office on the night before Pesach then one should search for chameitz in their office on the night before.

If one will not be home for Pesach then one should check their home for chameitz the night before they leave.

If one will be staying at someone else’s home for Pesach it is not the guests obligation to check. However, if one is renting the room (like at a hotel), they must check the room for chameitz. If they arrive at the hotel on the eve of Pesach, they must check for chameitz upon arrival.

One only says the blessing of bedikas chameitz if they are searching for chameitz the night before Pesach. Otherwise, the search is done without a blessing.

One makes a blessing before searching: Baruch… asher kid’shanu b’mitzvosov v’tzivanu al biur chameitz (Blessed are….Who sanctified us with His mitzvos and commanded us to destroy chameitz).

Since one’s home has been cleaned thoroughly for Pesach at this time there is a concern that the blessing be made is being said in vain. For this reason, there is a custom to hide ten pieces of bread before the search so that there is definitely some chameitz that must be found. That being said, the purpose of searching is obviously not just to find those pieces. One must search for any chameitz that they may have missed.

Although some search with a candle as this was done throughout history, it is totally acceptable and, if it is more efficient, even preferable to use a flashlight. One may leave their lights on if this facilitates the search.

This year (2025), we search for Chameitz on Thursday night.

Fast of the Firstborn

Male firstborns must fast on Erev Pesach. The reason for this fast is because the Jewish firstborns were spared on Pesach night from the plague of the firstborn. Therefore, Jewish firstborns acknowledge that they were not worthy of being saved and therefore fast as a sign of repentance on Erev Pesach.

There is another reason, suggested by Rabbi Yakov Kamenetzky Zt”l. On Erev Pesach, the entire Jewish People converged onto the Temple Mount to bring the Korban Pesach. Every family had to participate in this sacrifice and therefore to accommodate the masses of people, every single Kohen was put to work on Erev Pesach. Our tradition has it that the firstborns were supposed to be the priests but they lost their chance after participating in the Golden Calf. That being the case, the day most reminds the firstborns of their lost opportunity is Erev Pesach. Watching the Kohanim hard at work, running the ceremonies at the Temple was a sad reminder to the firstborns of what they could have been doing. It is for this reason, explains Rabbi Kamenetsky, that the firstborns fast on this day; to ask for forgiveness for their participation of the Golden Calf.

All male firstborns must fast; whether it is the mother’s firstborn, the father’s firstborn, whether it was a cesarean birth, whether the mother first had a miscarriage, and even if one is a convert firstborn.

The custom is that a firstborn may attend a Siyum, participate in the Siyum by eating some food served to celebrate, and once the fast is broken they may continue to eat the entire day. (This idea of ‘once the fast is broken it is permitted to eat the entire day’ does not apply to other fast days.)

If a firstborn was not able to attend a Siyum and knows that by fasting they will have a very difficult time participating properly in the Seder, they may break their fast but should not eat more than they have to.

According to some authorities if one is unable to attend a siyum they could participate by listening to the siyum on the phone.  

This year (2025), the fast will take place on Thursday.

Seder Night: Four Cups of WIne

One of the major themes of the seder is a celebration of our freedom. To demonstrate our freedom, the rabbis instituted the drinking of four cups of wine at the seder.

Ideally, the cups should be of a good wine. If one is concerned that the alcohol will affect them negatively or if they really dislike the taste of wine, they can drink a wine with a very low alcohol content. If that is challenging as well, one can use grape juice for the four cups.

The cup should be at least 3 ounces. This year, on the first night of Pesach one must use a cup that can hold at least 4.4 ounces (This is because it is Friday night and the obligation for Kiddush is Biblical).

One should drink the entire cup. If that is difficult, one can drink the majority of the cup.

It is customary to not pour one’s own cups.

Seder Night: Matzah

There is an obligation to eat matza three separate times at the seder; motzi matza,korech (Hillel’s sandwich), and for the afikomen.

The amount a person needs to eat is as follows:

Motzi Matza and Afikomen – 1/3 of a hand-made and 1/2 of a machine matza.

Korech – 1/4 of a hand-made and 1/3 of a machine matza.

One must recline when eating the matza and should try to eat each portion of matza within two minutes and at most four minutes.

Seder Night: Marror

There is an obligation to eat marror twice during the seder; once on its own and the other time in a sandwhich. The proper amount of marror to be eaten each time is one ounce worth of marror. If one is using lettuce to fulfill the mitzvah of marror, one big leaf or two stalks of lettuce suffice. One does not lean while eating marror.

 What is Kitniyot? What are the applications of this custom?

Kitniyot are certain vegetables that may not be eaten on Pesach according to Ashkenazic custom. Some common examples of kitniyot are alfalfa, beans, chickpeas, mustard, coriander, cumin, lentils, poppy seeds, peas, peanuts, rice, tofu, and soy.

If one has a restrictive diet due to health reasons, one should speak to a competent rabbi but in some circumstances they may eat kitniyot. The same holds true for very young children.

Kitniyot does not have to be sold but should be placed in a covered area to ensure that one will not eat it on Pesach.

Ashkenazim may eat food that was cooked in dishes that kitniyot was previously cooked in. So if one who is of Ashknezic descent were to visit the home of one who has Sefardic customs, he may not eat kitniyot, but he may eat non-kitniyot food cooked in that home even though the pots, pans, etc. were just used to cook kitniyot.
