Techniques
Fold
To combine a light mixture with a much heavier mixture. An example is beaten
egg whites combined with a cheese sauce as in making a cheese soufflé.
Place the heavier mixture in the bottom of a large bowl. Add the lighter mixture
and, using a rubber spatula, scrape along the outer edge of the bowl turning
the heavier mixture gently over the top of the lighter. Turn the bowl and repeat
until the two are well combined. The goal is to gently work the two together
without beating down the lighter mixture.
