Eggs are an exceptional source of complete protein (all nine essential amino acids), choline, selenium, and lutein. They contain approximately 70 calories per large egg with beneficial unsaturated fats concentrated in the yolk.
About
Eggs are the reproductive cells of domesticated fowl, primarily chickens (Gallus gallus domesticus), consisting of a protein-rich white (albumen), a fat-rich yolk, and a calcified shell. The yolk contains lecithin and cholesterol, contributing to the egg's emulsifying and binding properties, while the white is composed primarily of water and ovalbumin protein. Eggs vary in size and color depending on breed and diet, with brown and white shell varieties being most common in commerce. The flavor is mild and somewhat nutty, becoming richer when the yolk is emphasized in cooking.
Eggs are one of the most versatile and nutritionally complete foods, serving simultaneously as binding agent, emulsifier, leavening agent, and protein source. They are consumed globally across virtually all culinary traditions, prepared in countless methods from poaching to baking.
Culinary Uses
Eggs function across the culinary spectrum as both a primary ingredient and a technical component. They are prepared as standalone dishes—fried, scrambled, poached, baked, or hard-boiled—and feature prominently in breakfast traditions worldwide. Beyond simple egg dishes, eggs serve essential functions in baking (leavening in cakes and soufflés, binding in batters), sauce-making (emulsification in mayonnaise and hollandaise), pasta doughs, custards, and many other preparations.
The versatility of eggs extends to their use in meat binding, coating for fried foods, and clarification of broths. Regional cuisines incorporate eggs distinctively: Spanish tortilla española, French omelets, Chinese egg fried rice, Italian carbonara, and Middle Eastern shakshuka exemplify their centrality to diverse culinary traditions.
