QUESTION

Washington, D.C.

Can a treif chicken grilled directly on a kosher frying pan with no oil or anything be kashered?

ANSWER

It may be kashered with ליבון חמור.

There is a debate in the poskim as to what level of heat is required for ליבון חמור. According to some, it is sufficient that the pan be heated to the same temperature that it was when it absorbed the issur – based on the principle that “as it absorbed (the forbidden food), so it spits it out.”
