Question: what is the difference between durum and semolina flour?
Answer: The texture of semolina is heavier, like hard bread crumbs, and is more coarse than most milled flours. Durum flour is the fine ground powder left over from the milling process and also a product of semolina that's ground further. Durum flour is much finer than semolina, and resembles more traditional baking flours.
