229. Dough for Cooking
35:5 After Pesach, when yeast for dough is purchased from non-Jews, we must be sure to separate a larger quantity of challah than there was of yeast.
35:6 One who makes dough to cook or to fry should separate challah without saying the bracha. If he made even a small portion of the dough for baking, he would separate challah and recite the bracha.
