How to Prepare Cake Flour My Foolproof Homemade Recipe

Instructions:

1. Accurately measure one cup of all-purpose flour using the spoon and level method (spooning flour into the cup, then leveling off with a straight edge).
2. Remove 2 tablespoons of the measured all-purpose flour from the cup, returning it to the flour container. This is crucial for achieving the correct protein content.
3. Add 2 tablespoons of cornstarch to the remaining flour in the measuring cup. This helps to lower the protein content of the flour, creating a tender crumb.
4. Whisk the flour and cornstarch together vigorously for at least 30 seconds to ensure they are evenly combined. If using a sifter or fine-mesh sieve, sift the mixture 2-3 times for an even lighter result. This aerates the mixture, which helps even more with lightness.
5. Use the cake flour immediately in your recipe, or store in an airtight container in a cool, dry place for up to 3 months. Label the container clearly.
