glasses milk

Milk is a nutrient-dense liquid secretion from the mammary glands of lactating mammals, most commonly derived from domesticated cattle (Bos taurus) in culinary contexts, though goat, sheep, buffalo, and camel milk are also consumed globally. Cow's milk is an opaque, slightly sweet liquid with a pale cream to white color, consisting of water, lactose, proteins (casein and whey), fats, minerals, and vitamins. The fat content, flavor, and composition vary by breed, diet, and production method—whole milk typically contains 3.5–4% fat, while reduced-fat and skim versions are widely available.

Milk may be processed through pasteurization (heat treatment to eliminate pathogens), ultra-high temperature (UHT) treatment for extended shelf life, homogenization (to emulsify fat globules), or fermentation into yogurt, cheese, and other products. Regional preferences vary significantly: European cuisines favor cow's milk, while water buffalo milk is central to South Asian dairy traditions, and goat and sheep milk predominate in Mediterranean and Middle Eastern contexts.

Milk serves as both a primary ingredient and foundational component in cuisines worldwide. It is essential in the production of cheese, yogurt, butter, and cream—staples across European, American, and Asian cooking. In the kitchen, milk functions as a binding agent in batters, a base for sauces (béchamel, mornay), an enriching medium for soups and custards, and a liquid for cooking grains and legumes. It appears prominently in desserts, beverages (hot chocolate, coffee drinks, milk-based smoothies), and traditional preparations such as Indian kheer, Spanish flan, and French crème brûlée. Milk is also used in bread doughs to improve texture and browning, and in curries and stews across South Asian cuisines to add richness and balance heat.
