How to Convert APF & Cake Flour to Pastry Flour
- 1). Measure 1-1/3 cups of all-purpose flour by spooning it into a measuring cup and leveling it with the back of a knife or other straight-edged utensil. Do not shake or tap the cup to level the flour. Place a bowl on a kitchen scale, and adjust the scale reading until the display shows "0." Spoon 6-1/2 oz. of flour, or 185 g, into the bowl on the scale.
- 2). Spoon out 2/3 cup of cake flour into a measuring cup, and level it. Place another bowl on the scale, and adjust the scale "0." Add 3 oz. of cake flour, or 85 g, to the bowl. This is a 2-to-1 ratio when measured by volume and a 2.2-to-1 ratio when measured by weight.
- 3). Pour the all-purpose and cake flours into a sifter placed over a third bowl. Sift the combined flours four times to ensure the two are mixed thoroughly.
- 4). Use as directed in your pastry recipe. This process will produce 2 cups of pastry flour. Adjust the measurements accordingly, based on the amount of flour needed, using the ratio in Step 2.
