egg -- beaten

Beaten egg refers to chicken eggs that have been vigorously whisked or stirred to incorporate air and thoroughly combine the yolk and white into a homogeneous mixture. The process creates a uniform emulsion with a pale, foamy appearance that can range from lightly whisked to stiff peaks depending on the beating duration and technique. Beaten eggs serve as a crucial culinary preparation method rather than a distinct ingredient, transforming the physical and chemical properties of whole eggs to enable various cooking applications including baking, binding, coating, and creating light, aerated dishes.

The beating process fundamentally alters egg structure by incorporating air bubbles and breaking down proteins, which affects how eggs function in different recipes. Beaten eggs may be further differentiated based on beating intensity: lightly beaten (minimal aeration, used for scrambling and coating), moderately beaten (standard preparation for most recipes), and stiffly beaten egg whites (peaks that hold their shape, used for soufflés and meringues).

Beaten eggs function as a critical preparation method across numerous culinary applications. They are essential in baking—serving as a leavening agent in cakes, sponges, and soufflés due to the incorporated air and emulsifying properties. Beaten whole eggs bind ingredients in preparations like meatloaf and fish cakes, while beaten egg whites create meringues, pavlovas, and mousse-based desserts. In savory cooking, beaten eggs coat ingredients for frying (à l'anglaise), scramble into custards and custard-based sauces, and form the base for omelets and frittatas. The technique also enables egg-based emulsions like mayonnaise and hollandaise sauce when combined with oil or butter.
