Which type of dough requires Challah?

Hi,

My most recent post, regarding the type of dough that requires challah, was incomplete; I have now deleted it from the website archive. Here is a more complete, and accurate, description of the law:

Grain-based dough which is baked in an oven requires challah separation, whether it is solid dough (as in bread dough) or more of a liquid batter (as in cookies, brownies or cake). Grain-based dough which is boiled in water or fried does not require challah separation, whether it is solid dough or more of a liquid batter.

The only exception to these rules is a solid dough which was intended for baking at the mixing stage, but was then boiled or fried. Because this dough was intended for baking at the mixing stage, one must separate challah.

Note that for a liquid batter, one separates challah after the baking solidifies it, according to the Star-K here.

Have a great day,
