Pastry flour costs a lot more than all-purpose flour. Here’s how to make a quick (and affordable) pastry flour substitute that’ll work beautifully in any recipe that calls for it.
What is Pastry Flour?
Pastry flour is a low-protein flour, made from soft wheat. It contains 8-9% protein. By comparison, all-purpose contains 9-12%. That may not sound like a big difference, but less protein, means less gluten, and for bakers, that translates into baked goods that are lighter and more tender. Pastry flour is typically used to make pie crusts, cookies, pastries, biscuits and other baked goods that are leavened with baking soda or baking powder. It’s seldom used in recipes that are leavened with yeast. It just doesn’t contain enough protein to create the elasticity that yeasted baked goods require.
How to Make a Homemade Pastry Flour Substitute
For every cup of cake flour called for: Combine 2/3 cup of all-purpose flour and 1/3 cup of cake flour. This will give you a flour that falls within the protein range of pastry flour.
If you don’t have cake flour . . . Measure two teaspoons of cornstarch (or arrowrooot powder) into a one-cup measuring cup. Then, fill the rest of the cup with all-purpose flour, and level the top to remove any excess flour. Mix or sift the ingredients together to ensure the cornstarch (or arrowroot) is well incorporated.
If you don’t have the ingredients to make either of these substitutes . . . Just use all-purpose flour in place of the pastry flour that’s called out. Your recipe may not turn out quite as light and tender, but it’ll still taste great. If anyone complains, send them to the store for pastry flour, the next time you run out.
