King Arthur Pastry Flour is a finely milled flour that is perfect for delicate pastries and baked goods, such as pie crusts, cookies, and cakes. It has a lower protein content than all-purpose flour, which helps produce a tender and flaky texture. This flour is made from 100% American wheat and is unbleached and unbromated, making it a great choice for those seeking high-quality, natural ingredients in their baking.
