eggs or egg whites

DairyYear-round; commercial production provides consistent supply. Backyard and pasture-raised flocks may show seasonal variation in production, with peak laying in spring and early summer.

Eggs are a complete protein source containing all nine essential amino acids, choline, and lutein; egg whites provide lean protein with minimal fat, while yolks concentrate vitamins A, D, E, and selenium.

About

The egg is the reproductive body produced by female fowl, primarily chickens (Gallus gallus domesticus), consisting of a nutrient-dense yolk enclosed within a protein-rich albumen and protective calcium carbonate shell. Eggs are ovoid in shape, typically 50-70 grams in weight, with a pale yellow yolk and clear to slightly opaque white. The composition varies by breed and diet, with yolks ranging from pale to deep golden-orange depending on the hen's feed. Egg whites consist almost entirely of water and ovalbumin protein, forming the majority of the egg's weight and providing structure and lift when whipped.

Eggs are produced year-round on commercial farms and are a staple protein source globally, with culinary applications spanning virtually every cuisine and cooking method. Free-range, pasture-raised, and organic eggs command premium prices and offer varied yolk colors and flavor profiles.

Culinary Uses

Eggs function as both primary ingredient and binding/leavening agent across cuisines. Whole eggs are prepared as scrambled, fried, poached, boiled, or baked; in such applications they serve as complete meals or components of breakfast traditions worldwide. Egg whites are whipped into meringues, soufflés, and angel food cakes, where their protein foaming properties create structure and height. Both whole eggs and whites are essential in custards, mayonnaise, pasta dough, and cake batters, where they emulsify, bind, or add richness. In Asian cuisines, eggs are steamed, preserved as century eggs or salted eggs, or incorporated into noodle dishes and stir-fries.

Forms & Preparations

Whole egg — Uncooked egg in shell; the standard form for most culinary applications including cooking methods and baking.
Egg white — Separated albumen used for whipping into meringues, soufflés, or protein-forward applications where fat-free structure is needed.
Egg yolk — Rich, nutrient-dense yolk used for custards, emulsified sauces like hollandaise and mayonnaise, or pasta dough.
Pasteurized liquid eggs — Whole eggs or whites processed and heat-treated for food safety; convenient for large-scale use and shelf stability.
Powdered egg — Dehydrated whole eggs or whites; reconstituted with water for baking or cooking; used in camping, emergency supplies, and commercial food production.
Century egg (pídàn) — Preserved egg where yolk and white are cured in alkaline materials, developing dark color and distinctive savory flavor; traditional in Chinese cuisine.
