fluid oz. milk

Milk is a nutrient-rich liquid secreted by mammary glands of lactating mammals, most commonly cattle (Bos taurus), though also produced by goats, sheep, and other species. Cow's milk, the predominant form in Western cuisine, is an opaque white or slightly yellow emulsion composed of water, proteins (casein and whey), milk fat, lactose, and minerals including calcium and phosphorus. The flavor profile is mild, slightly sweet, and creamy, with variations depending on breed, diet, and production methods. Pasteurization (heat treatment) is standard in commercial production to ensure safety, while full-fat, reduced-fat, and skim varieties are created through mechanical separation of cream.

Raw milk, unpasteurized milk, and milk from different animal sources each exhibit distinct flavor characteristics—goat's milk, for example, carries a distinctive tangy note—and are used differently across culinary traditions.

Milk serves as a fundamental ingredient across global cuisines, functioning as both a standalone beverage and a critical component in cooking. It is essential in sauces (béchamel, crème fraîche bases), custards, ice cream, puddings, and baked goods where it contributes moisture, fat, and protein structure. In dairy-producing cultures, milk forms the basis for cheese, yogurt, and butter. Regional applications include Indian kheer (rice pudding), French crème brûlée, and Latin American atole. Milk also serves as a cooking medium for grains and legumes, enriching their texture and flavor. The choice of milk type—whole, skim, or alternative—affects final dish texture and richness.
