Egg whites
Essentially neutral and clean; when cooked, they set into a firm, rubbery-to-tender white depending on heat; whipped, they become airy and cloudlike.
Lens analyzedEgg whites are the clear albumin surrounding the yolk — virtually fat-free and rich in protein. They are essential for aeration in meringues and soufflés, for binding in baked goods, and as a lean protein boost in cooking.
Where it comes from
Egg whites gained culinary recognition as soon as cooks discovered their extraordinary ability to trap air — producing stable foams that could be baked into crisp meringues or folded into light mousses. French pastry elevated egg-white cookery to an art form from the seventeenth century onward, and these techniques spread across Europe and into North American baking traditions. Today, carton egg whites have made it easy to use large quantities without the waste of unused yolks.
Varieties — Fresh egg whites from whole eggs; carton liquid egg whites (pasteurized, convenient, good for cooking but slightly less effective for stiff meringue peaks); powdered egg whites (for shelf stability and royal icing).
French meringue — whipped egg whites sweetened with sugar and baked until crisp — is the foundation of Vacherin, île flottante, and dacquoise, each representing a different textural expression of the same simple mixture.
In a modern kitchen — Fat is the enemy of meringue — even a trace of yolk or a greasy bowl will prevent whites from whipping to stiff peaks. Ensure all equipment is immaculately clean and grease-free, and add a pinch of cream of tartar to stabilize the foam.
Buying it
For baking that requires peak volume, use fresh egg whites from whole eggs — carton whites are pasteurized at a temperature that slightly denatures proteins and may not whip as high. For cooking scrambles and omelets, carton egg whites are perfectly convenient.
Storing it
Store in a sealed container in the coldest part of the fridge. Use within a few days of separating, and discard if they turn cloudy, pink-tinged, or develop an off smell.
Keeps about 14 days in the fridge.
