egg; beaten

Eggs are the reproductive cells of avian species, most commonly sourced from domesticated chickens (Gallus gallus domesticus). A beaten or whisked egg is one in which the yolk and albumen (white) have been mechanically agitated with a fork, whisk, or electric mixer until combined into a homogeneous mixture. The beating action incorporates air, creating a lighter texture and increasing volume. Beaten eggs may range from lightly combined to stiff peaks depending on the vigor and duration of beating. The emulsifying properties of the yolk and the foam-forming capability of the albumen make beaten eggs essential in numerous culinary applications.

The color of beaten eggs ranges from pale yellow to golden, depending on the chicken breed and diet. The texture becomes increasingly airy and voluminous with extended beating, particularly when air incorporation is the goal. Room-temperature eggs beat more efficiently and incorporate air more readily than cold eggs.

Beaten eggs serve multiple functions across cuisines: as a binding agent in meatballs, patties, and baked goods; as a leavening agent in cakes, soufflés, and meringues; as a coating for breaded items; and as the base for custards, scrambled eggs, and omelets. In pastry work, beaten egg whites create mousses, chiffon cakes, and pavlovas, while whole beaten eggs emulsify batters and contribute structure to baked items. Beaten eggs also serve as an egg wash to provide gloss and browning on pastries and breads. Different beating intensities are used strategically: gentle mixing for batters, vigorous beating for maximum volume in meringues and angel food cakes.
