00 flour, also known as doppio zero flour, is a finely milled Italian flour that is highly refined and low in protein content. It is commonly used in Italian cooking, particularly for making pasta and pizza dough. The "00" refers to the texture of the flour, with "00" being the finest grade. This fine texture makes it ideal for producing a smooth, elastic dough that can be easily rolled out and shaped. Additionally, because of its low protein content, 00 flour produces a tender and delicate final product, whether it's pasta, pizza crust, or certain types of bread.
