Eating Egg Matzah On Erev Pesach

April 2nd, 2025|Kashrut, Orach Chayim, Pesach|

QUESTION

Riverdale, NY

Rav Linzer, If one is using egg matzah for lechem mishnah for Shabbat/Erev Pesach, can it be eaten after the point that one can no longer eat chameitz? Also, does one need to avoid putting egg matzah in hot soup (keli shelishi) on Shabbat Erev Pesach, if it’s in Pesach keilim?

ANSWER

(NOTE – All discussions of egg matzah here that are a problem only for Ashkenazim are egg matzahs that have

Kashering a Griddle for Pesach

March 22nd, 2025|Kashrut, Orach Chayim, Pesach, Yoreh De'ah|

QUESTION

Chicago, IL

Can this be kashered for Pesach? Griddle for making pancakes used with batter.

ANSWER

In general, we rule that chameitz, even during the rest of the year, is considered to be איסורא בלע, and when absorbed directly via the fire requires libun chamor (Shulchan Arukh OC 451:4). That is normally defined at about 700 degrees. I imagine that that is not possible here and that a blow torch or the like would destroy it.

There are, however, poskim who rule that libun chamor is the same as the hottest temperature the object got to. According to this you

Whiskey sold after Pesach

May 1st, 2023|Moadim, Pesach|

QUESTION

Ohio

When whiskey is sold to gentiles for פסח, does it wipe away any labelling of it as חמץ שעבר עליו הפסח? E.g. when a Bourbon had been created by Jews (and unquestionably is חמץ שעבר עליו הפסח), but is then sold to gentiles, does it lose its status as חמץ שעבר עליו הפסח? And, if not, is it still permissible to drink?

Here are three real-life situations I have encountered with regard to this question:
1) My gentile neighbor offers me to drink of his own bottles of a Bourbon that had been

Using Pet Food That is Less Than 50% Chametz on Pesach

March 28th, 2023|Orach Chayim, Pesach|

QUESTION

Denver, CO

Rabbi Linzer, what is your view on using pet food on Pesach that is ta’arovet chametz—less than 50% percent grain—instead of trying to find grain free pet food? This is important to dog owners who find it difficult to switch foods. I understand that the hesitancy on this is whether or not dog food can be classified as nifsal mei’achilat adam (not fit for human consumption). It seems to me that even though it may be made tolerable to

Halakhic Status of Bread Made With Both Wheat and Almond Flour

April 11th, 2021|Berakhot, Orach Chayim, Pesach, Yoreh De'ah|

QUESTION

Washington, D.C.

A bread made with mostly rice flour but some wheat flour would be HaMotzi if you could taste the wheat. What about if instead it were made with almond flour? Would the same taste rule apply or would you need rov?

ANSWER

A very relevant question for those who are gluten intolerant. So how do they make HaMotzi or eat matzah? One answer is to use oats, which is one of the 5 species of grain. However, from what I have heard, it is very hard to eat bread that is completely made out of oats. (Also, from an academic perspective, it is questionable if oats

Ordering Chameitz During Chol HaMoed Pesach

April 2nd, 2021|Orach Chayim, Pesach|

QUESTION

Chicago, IL

What is the Rosh Yeshiva’s position on ordering chameitz from Amazon/online grocery/etc. during Chol HaMoed?

ANSWER

Totally אסור. You will own חמץ on Pesach even if not yet in your possession. The only way it can be okay is if the purchase doesn’t take effect until the food is delivered. I am assuming that is the case but it should be checked out. They certainly take your money up front. Let’s say they never deliver – do you ask for a refund or do they say that the order never went through? It is true that your item won’t be selected from

Use of Hamster Food on Pesach

March 22nd, 2021|Orach Chayim, Pesach|

QUESTION

Philadelphia, PA

Can I use hamster food (a seed mix that has raw wheat, oats, barley, rye spelt) like this for Pesach?

ANSWER

Why should it be okay? We cannot assume that they didn’t use water. The only question would be if it were fit to be eaten by humans (ignoring the “gross” factor because they know it is hamster food). If it were never fit for humans, then it is chameitz nukshah, so one does not transgress de’orayta of bal yera’eh, but it is still assur derabanan to keep. See Mishnah Berurah 442:2. If it is not fit for achilat kelev,

The Status of Utensils Never User With Chameitz That Are Stored in Proximity to Chameitz

March 14th, 2021|Kashrut, Orach Chayim, Pesach, Yoreh De'ah|

QUESTION

Chicago, IL

What is your guidance for kashering kitchen utensils that are never used for chameitz but are kept in the kitchen during the year. For example, a French press for making coffee that sits on the counter top and is washed with chameitz in the sink or dishwasher (with soap)? What about a special rack for roasting liver which is only used for liver and never with chameitz in the oven at the same time?

ANSWER

If it sits in the kitchen, but never comes in hot contact with anything chameitz, then you can use it. Just wash it off and you are

Chametz She’Avar Alav HaPesach

November 23rd, 2020|Orach Chayim, Pesach|

QUESTION

Westchester, NY

I have some חמץ שעבר עליו את הפסח. My school is doing a food drive this week. Can I donate my חמץ without concern for הנאה? The food drive is also a competition between classes. If I put it in one of the classes’ boxes, would that be a problem?

ANSWER

The Gemara says in a different context that a gift is like a sale, since it usually is in repayment of some good that the person did for you (a little cynical view on
