So which type of flour is used in most 00 products? Semolina? Most 00 flour I've seen before is white colored which means it has to be a different type of flour than the traditional yellow colored semolina flour.
try searching i remember someone started a thread with the same question. 00 just means its really fine, semolina is different. i have used all purpous flour and it turns out alright(have made ravioli and pasta with it), at work we use 00 for gnocci and pasta, comes out really delicate and delicious. i ahvent used semolina much but i have a few times.
