Eggs are an excellent source of complete protein containing all nine essential amino acids, and provide choline, selenium, and lutein. They are rich in vitamin B12 and vitamin D (especially when from pasture-raised or supplemented hens), and the yolk contains beneficial compounds including zeaxanthin and betaine.
About
Eggs are the reproductive bodies produced by female birds, most commonly chicken (Gallus gallus domesticus), consisting of a protein-rich albumen (white), a nutrient-dense yolk, and a protective calcium carbonate shell. The chicken egg is the most widely consumed egg globally, though duck, quail, goose, and emu eggs are used in various cuisines. Eggs possess a neutral flavor with subtle richness, and their composition—approximately 73% water, 13% protein, and 12% fat—makes them uniquely functional in cooking. The yolk contributes both fat-soluble vitamins and emulsifying properties due to lecithin, while the white provides structure and stability when whipped. Eggs vary in color (white, brown, or speckled shells) based on chicken breed, though shell color does not affect nutritional content or flavor.
Different grades and sizes are standardized for commerce (large, extra-large, etc.), and eggs may be labeled by farming method (free-range, cage-free, conventional) and diet enrichment (omega-3, pasture-raised). The freshness of an egg is indicated by the position of the yolk and air cell size when cracked open—fresh eggs have centered yolks and minimal air space.
Culinary Uses
Eggs serve as a foundational ingredient across virtually all cuisines, functioning as a binder, emulsifier, leavening agent, and thickener in addition to being prepared as standalone dishes. They are poached, fried, scrambled, soft or hard-boiled, baked, or incorporated into omelets and frittatas. In baking and pastry work, eggs provide structure to cakes and custards, emulsification in mayonnaise and hollandaise, and leavening through foam formation when whipped. They feature prominently in custards, meringues, soufflés, and quiches, and are essential for binding farce in charcuterie and breadings. Eggs are also prepared as the base for crème brûlée, ice cream, and countless sauces. Regional preparations include Chinese tea eggs (marbled with soy and spices), Japanese tamago (sweet egg omelet), and Spanish tortilla española (potato and onion frittata).
