Folding

Means of mixing a light, airy mixture (like whipped cream or beaten egg whites) with a thick, heavier mixture so as not to flatten the air out of the resulting dough. Pour the light mixture over the heavy mixture in a large bowl. With a rubber spatula, cut down to the bottom of the bowl, turn the spatula, carefully lift up some of the mixture and turn over gently onto the top of the mixture. Give the bowl a quarter turn, and repeat only until the mixture is blended.
