I have a question about the recipe "Butternut squash ravioli with crispy sage butter sauce" from cheese1227. What is 00 pasta flour?
It is a European finely ground flour made from durum wheat. It usually has a mid-range amount of protein, which means the gluten is suitable for bread and pasta. All purpose flour can be substituted, although the texture may be a bit different from that of the 00 flour.
