x egg whites
Egg whites are nearly fat-free and provide approximately 3.6 grams of complete protein per large egg white, making them a lean protein source; they also contain small amounts of minerals including potassium and magnesium.
About
Egg whites are the transparent, viscous albumen portion of chicken eggs (Gallus gallus domesticus), separated from the yolk. Composed primarily of water (approximately 90%) and proteins—chiefly ovalbumin, ovotransferrin, ovomucoid, and ovomucin—egg whites are odorless and flavorless, with a gelatinous consistency when raw that transforms during cooking through protein denaturation. The protein content and coagulation properties of egg whites make them uniquely functional in culinary applications, capable of forming stable foams, gels, and emulsions.
Culinary Uses
Egg whites serve as a critical leavening agent and binder in baking, creating structure in cakes, soufflés, and meringues through aeration and protein networks. In pastry work, whipped egg whites incorporate air to produce light mousses, chiffon pies, and pavlovas. They function as a clarifying agent in consommés and stocks, trapping impurities to produce crystal-clear broths. Beyond sweet applications, egg whites bind forcemeats in charcuterie, coat foods for frying, and stabilize custards and hollandaise. Raw or gently cooked egg whites appear in traditional cocktails and custard-based preparations.
