Double Wrapping Pesach Food In Chometz Oven

Wow! great question.

Ask your Rabbi.

Once your there, ask him all the rest of your halacha questions, and leave them out of this place.

Great question. Mishna Berura talkes about it:

???? ????? ??? ??”? ???? ? ?”? ?”?

What is wrong with koshering properly your guest’s oven, heating kosher food for both of you, and then after you leave, the oven remains kosher at least for a while?

Maybe rebdoniel is contemplating for purposes of feeding his family in the days leading up to Pesach in a house already Kosher l’Pesach when one is surely not bound by all the extra Chumros of Pesach.

Double wrapping helps lekatchilah. The wrapping keeps out any reicha or zeiah. The outside wrapper becomes chametz, the bliaos from outside wrapper can’t travel to inner wrapper without a liquid medium. That is the purpose of double wrapper.

It would be hard to find one Baalhabasta ( Jewish Torahdik housewife) to allow it……….. even if you find seforim permitting.

Just make sure to have your non Jewish friend turn on the oven so you avoid any potential basar b’chalav cooking shaylos. That is, if there are meat and milk drippings in the oven and you turn it on you have a problem of cooking milk and meat together.

Also, I don’t know of any balabustah who would allow it, but I also don’t know of any who would have eaten on pesach in their grandmothers’ kitchens. Where food was prepared for pesach for weeks in advance in the regular chometz kitchen. All they did was roll back the tablecloth and designate the area for pesach. I don’t think any balabustas today would dream of doing that, and yet that is not a problem. Neither is not baking chometz in your pesach oven.

Remember, on Pesach even a mah shehu is not batul, whereas year-round the issur is butail with 1/60.

I think your question is really two questions:

-a Jew wishes to heat his kosher food in his nonjewish friend’s oven

-we wish to heat chometz in an oven which is already KLP and are trying to avoid having to kosher it all over again.

In the first situation, I would clean the oven and then do self-clean cycle or set at max heat for a while (never had a nonjew or nonobservant jew make unpleasant comments, of course I always offered to share the food), but I am aware of many leniences (even beyond what was posted). The leniences come from the difficult reality of our ancestors, who sometimes used the local baker’s oven to cook.

The second is a little bit different, because the oven is yours.

Personally, I am aware that we have to observe Pesach for eight days only and no more – that’s where beer and whisky and restaurants come handy :-))

Ver Bin Ich, I am quite sure our grandmothers and grandfathers themselves would not eat in their own kitchen. It was not easy life, I am sure they would tell us we should realize how blessed we are, not being forced to rely on certain leniences.
