“Just dont regift Prune or Mon Hamantashn. Most people dont like them”
Maybe that’s why you should regift them. Then they will have something to regift :).
More importantly, make sure you don’t regift to the sender. Or to someone who is likely to regift to the sender. Of course, you have no idea where something might end up. So best is to only regift things that could have been sent by anyone (definitely not home-baked – that would be a bad idea anyhow because they will assume you baked it, and they might trust your kashrus and not the other person’s. Also, it might be genaivas daas, since they will think that you are a good baker.)
Best to regift things that are not original like taffies or oranges/apples.
