Eggs are a complete protein containing all nine essential amino acids, and are rich in choline, selenium, and antioxidants lutein and zeaxanthin. The yolk contains cholesterol and fat-soluble vitamins (A, D, E, K), while the white is nearly fat-free.

About

The egg is the reproductive body produced by female fowl, primarily chickens (Gallus gallus domesticus), consisting of a protein-rich white (albumen), a fatty yolk, and a protective shell. Eggs have been a dietary staple across cultures for millennia, valued for their nutritional completeness and culinary versatility. A standard large chicken egg weighs approximately 50 grams and contains distinct structural components: the transparent albumen solidifies when heated and contains primarily water and ovalbumin protein, while the golden yolk contains fats, cholesterol, and fat-soluble vitamins. The shell, composed of calcium carbonate, is porous and can range in color from white to brown depending on the breed of hen, though interior composition remains consistent regardless of shell color.

Beyond chicken eggs, other poultry eggs (quail, duck, goose) are used regionally, though chicken eggs dominate global consumption. Free-range, organic, and pastured variants are available, with differences in yolk color and fatty acid profiles reflecting the hen's diet.

Culinary Uses

Eggs function as a fundamental ingredient across virtually all cuisines, serving as binder, emulsifier, leavening agent, and primary protein source. They are prepared in numerous ways: fried, scrambled, poached, boiled, and baked into custards, meringues, and cakes. In baking, eggs provide structure and moisture; in mayonnaise and hollandaise, they emulsify fats into stable sauces. Egg whites, which contain primarily albumin protein, are whipped into meringues and foams for mousses and soufflés. Whole eggs bind meatloaves and forcemeats, while yolks enrich pasta doughs, ice creams, and pastry creams. The ingredient appears in breakfast preparations (omelets, frittatas), soups (egg drop soup), noodle dishes, and countless baked goods.

Forms & Preparations

Whole egg — Intact with shell; cooked or cracked raw into preparations. Primary form for scrambled, fried, poached, and boiled preparations.
Separated whites and yolks — Albumen and yolk divided for distinct culinary purposes. Whites whipped for meringues; yolks enriching sauces and custards.
Beaten or whisked — Whole eggs or whites agitated to incorporate air, used in omelets, batters, and foams for leavening and texture.
Powder (dried) — Whole eggs, whites, or yolks dehydrated and powdered; shelf-stable alternative for baking and cooking, reconstituted with water.
Pasteurized liquid — Whole eggs or whites processed for food safety; used in commercial baking and in venues requiring pathogen reduction.
Cooked (hard-boiled, soft-boiled, poached) — Heat-treated to various doneness levels; ready-to-eat or used as components in salads, sandwiches, and composed dishes.
