fluid ounces milk

Milk is a nutrient-dense liquid secreted by mammary glands of female mammals to nourish their young; in culinary contexts, this term almost universally refers to cow's milk (Bos taurus). Cow's milk is an opaque white or cream-colored emulsion composed of water (approximately 87%), milk fat globules, lactose (milk sugar), casein and whey proteins, minerals (calcium, phosphorus, potassium), and vitamins. The flavor is mildly sweet and creamy, with variations depending on the dairy breed, animal diet, and processing method. Common culinary varieties include whole milk (3.5-4% fat), reduced-fat milk (2%), low-fat milk (1%), and skim milk (0-0.5% fat); pasteurized milk is heat-treated for safety, while raw milk remains unpasteurized.

Milk serves as a foundational ingredient across virtually all culinary traditions. It is used in beverages both hot (coffee, tea, hot chocolate) and cold (smoothies, milkshakes), as a base for soups, sauces (béchamel, mornay), and custards, and in baking for cakes, breads, and pastries. Milk is essential in cheese and butter production, yogurt fermentation, and ice cream manufacture. In cooking, it tenderizes meat, enriches braises and stews, and modulates spice intensity in curries and cream-based dishes. Different fat contents serve different purposes: whole milk creates richer sauces and desserts, while lower-fat versions suit beverages and lighter preparations.
