Bedikat Chametz When Home on the 14th but Away for Pesach

April 7th, 2026|Orach Chayim, Pesach|

QUESTION

Someone will be home on the night of the 14th, but will then travel the next morning to the place where he will be staying for Pesach.

For his own home — since he will be there at the time of bedikat chametz — should he perform a full bedikat chametz with a berakhah?

And what about the next day, when he arrives at his Pesach location — does he make a berakhah on the bedikah there? Does it make a difference whether he arrives before or after the time of biur chametz?

ANSWER

If he will be returning to his home during Pesach,

Donating Chametz to a Food Pantry Before Pesach With Pickup on Chol HaMoed

April 6th, 2026|Moadim, Orach Chayim, Pesach|

QUESTION

A member of my shul wants to donate food to a food pantry that will be picking up during Chol HaMoed. Can they be mafkir (declare ownerless) the food and leave it on their porch for pick up before Pesach? My concern is that no one will know about the hefker (ownerless) status of the food—so does that really count as hefker?

ANSWER

I think that’s fine.

It is true that hefker cannot be done ba’lev (without any outward expression) (see Ran, Pesachim 1a, ד״ה ומהו), since devarim she’ba’lev einam devarim (unexpressed intentions are not legally significant). Nevertheless, taking

Donating Chametz to a Food Pantry before Pesach and Volunteering There on Pesach

April 6th, 2026|Non-Jews and Other Religions, Orach Chayim, Pesach|

QUESTION

One of the local Reform shuls here runs a wonderful food pantry. They partner with a local organization and mainly serve non-Jews.

Our communities are very connected, and people from our shul volunteer there and donate food items. Can people donate chametz there before Pesach? I reached out to their Rabbi, but I’m not even sure what we would require, if anything. (Meaning does the shul own the chametz?)

Also, no one has asked me this, but I was curious: Can one volunteer there over Pesach?

ANSWER

The question is, as you note, who really owns the food in the food pantry.

Induction Stove Tops for Milk and Meat, and Pesach

March 15th, 2026|Kashrut, Pesach, Yoreh De'ah|

QUESTION

Can the Rosh Yeshivah’s clarify his position regarding induction stovetops? Having read/watched his views on cooking with it on Yom tov and regarding its status vis a vis bishul akum, would it be correct that the same burner could be used for both meat and dairy?

If so:

A. Would this be permitted even on the same day?
B. If there are spills, would one be required to wipe the surface between uses, or would that simply be recommended as a best practice?

As well, regarding Pesach, would the induction surface not require kashering, but

Starting Seder Earlier

March 28th, 2025|Kiddush, Seudah, Havdalah, Marriage and Family, Orach Chayim, Pesach, Uncategorized|

QUESTION

What is the earliest time for the first cup for the start of the seder

ANSWER
It is common during the summertime to bring in Shabbat early and to make kiddush and have our Friday night meal before it gets dark. This is based on the principle of tosefet Shabbat, extending the sanctity of Shabbat into the day before. However, when it comes to Pesach, many Rishonim rule that matzah may not be eaten before it is full nightfall (tzeit hakokhavim) because of a number of verses that state that  matzah and the korban pesach (Pesach

Kashering Countertops

March 23rd, 2025|Moadim, Pesach|

The above video is about koshering during the year. When it comes to Pesach, there is a chumrah to kasher countertops, regardless (see SA OH 451:20). This should be followed when possible, however if there is concern that damage will result, one need not follow this chumrah.

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
