If one puts the challah on top of a pot to keep warm and there is a screw sticking up on top of the pot. Can one stick the challah into the screw to hold it on top of the pot? This bores a small hole through the challah. My husband claims it’s still shalem as the piece of challah is pushed in, not removed. Is this correct? Is the challah still considered shalem?
Technically the challos are whole and they can be used for lechem mishna. Even if the challos are missing a little bit, they are still considered shalem if they look whole in people’s eyes (missing less than 1/48th). However, l’chatchila the challos should be truly whole and not missing anything or even cracked.
