Reply To: Questions on Yoreh Deah, Choshen Mishpat

Sorry, I took no position in that thread, and I will not be doing so in this thread either. I have not learned those sugyos well enough.

But someone called my brother on Friday that he had put his milchig lid onto his fleishig pot on friday afternoon.

Since the lid was not ben yomo, and not dirty, and did not have a peaked top, it was certainly muttar on erev shabbos. shach 93:4.

If you exchange pot lids, you should always ask a shaila.
