For baking challah, I use 17 cups of flour which I believe is the minimum shiur for taking challah with a bracha. Can I then break off a piece of the raw dough and freeze it for use during the week or do I need to bake all the dough at once to be able to make the bracha?
Answer:
You don’t need to bake the dough at once. Even if you put some of it away, you can still separate challah with a berachah.
