Double Zero

Also called “Tipo 00” or “Caputo.” 00 is a very finely ground wheat flour that is ideally suited to pizza and pasta-making. The “00” refers to the milling of the flour, not the protein content, and happens to be the finest grade of Italian flour. In the United States, 00 flour is available in some grocery stores, Italian specialty stores, and through online retailers. If you are unable to find 00 flour, you may substitute all-purpose flour. If the dough is too dry, add a small amount of water.
