Dessert recipes often cause an egg imbalance in the kitchen. Separating eggs for curds, ice cream bases, meringues, or angel food cakes leaves you with an excess of either yolks and whites. The most convenient way to keep them stored for months? In the freezer!
Egg whites can be frozen as-is, and will lose only a little of their foaming power in the freezer. Egg yolks, however, need some special treatment to keep from becoming pasty when thawed. Thoroughly mix one teaspoon of sugar with each egg yolk before storing; this will keep the egg proteins fluid after freezing.
For the most flexibility, freeze whites and yolks individually in ice cube trays, then pop them into a larger freezer-safe container. Once frozen, they will keep for several months.
