*Cake flour can be made by measuring out your flour; for every cup of flour, take out 2 tablespoons of flour. Add 2 tablespoons of corn starch instead. Mix together to combine.
**To make your own buttermilk, measure out a scant cup of milk and add 1 tablespoon of lemon juice or vinegar (this recipe calls for 2 1/4 cups, so measure accordingly). Let stand 5-10 minutes.
