- 1 scant cup all-purpose flour (bleached or unbleached)
- 2 Tbsp cornstarch or arrowroot powder
Spoon cornstarch or arrowroot into a one-cup measure cup.
Spoon all-purpose flour into the cup, until full. Level off any excess.
Then, pour the mixture into a bowl, and stir to combine the cornstarch and flour. A flour sifter is even better, if you have one.
Use in place of one cup of cake flour.
To Make a Larger Batch:
2 cups = 1/4 cup cornstarch (or arrowroot powder) + 1-3/4 cup all-purpose flour
8 cups (the equivalent of one store-bought box) = 1 cup cornstarch (or arrowroot powder) + 7 cups all-purpose flour
- In the UK, all-purpose flour is called plain flour, and cornstarch is called corn flour.
- Nutrition facts are based on using unbleached flour and cornstarch
