Is there some halacha about bread not allowed to be dairy? I was reading an advertisement in a store in Brooklyn and it was written on the paper something about bread not being allowed to be dairy. Is this a halacha? I have never heard of this before, but I looked around and all the bread I saw was "pareve." Maybe this halacha just never came my way.
Yes, it's prohibited to bake bread either with milk or with meat. That is, bread must be pareve. This is stated in Shulchan Aruch as follows: "It is forbidden to knead dough for bread with milk, in case a person should (accidentally) eat it with meat...It is similarly forbidden to bake bread in the oven with meat fat "
But if you mark the bread with some identifying symbol before baking, or if you bake it in an identifying shape so that it's clear that this bread is not pareve, then it is permitted to make it dairy or meaty. Since it's marked, you won't mistake it as pareve. (Marking it after baking doesn't help, and such bread may not be eaten.)
For example, I have heard that the Badatz Eida Charedit kashrut supervisory board in Jerusalem requires all dairy pastries to be either triangle or moon-shaped for this reason.
