“Folding” is a method of combining ingredients without knocking the air out of the mixture, such as the folding of dry ingredients into whipped egg whites for these angel food cupcakes. Here’s how it’s done:
- Use a rubber spatula and make sure your bowl is big enough.
- Using the spatula, cut through the egg whites at 90 degree angle to the bottom of the bowl.
- Scoop the egg whites and fold it on top of itself, incorporating the dry ingredients.
- Rotate bowl a quarter turn and repeat only just until no streaks of dry ingredients remain. Do not over mix.
