oz/150 g butter

Butter is a dairy fat product produced by churning cream or milk to separate the butterfat from the buttermilk. The result is a solid or semi-solid emulsion of water dispersed in butterfat, typically containing 80-82% milk fat, 15-17% water, and 1-2% milk solids by weight. Native to northern European and Indo-Iranian regions where dairy herding predominated, butter has been produced for millennia and remains a cornerstone of European, Indian, and Middle Eastern cuisines. Quality varies by source milk, production method, and feed; cultured butter, made from fermented cream, develops complex flavor notes and is prized in professional kitchens.

Butter's flavor ranges from sweet and mild to rich and tangy depending on the dairy source, pasteurization method, and age. Clarified butter (ghee) and browned butter (beurre noisette) represent important culinary variations with distinct characteristics and applications. Color varies from pale yellow to deep golden depending on cattle diet and season.

Butter serves as a fundamental cooking fat, flavoring agent, and emulsifier across global cuisines. It is used for sautéing vegetables, pan-frying proteins, and creating pan sauces; whisked into creams and beurre blanc; creamed with sugar as a base for cakes, cookies, and pastries; layered in laminated doughs for croissants and puff pastry; and melted as a finishing enrichment or dipping sauce. In Indian cuisine, ghee (clarified butter) is essential for tempering spices and cooking rice and breads. Temperate European cooking relies on butter for both savory and sweet applications, while it also appears in Middle Eastern and North African preparations. Room-temperature butter is essential for aerating batters and doughs through mechanical incorporation.
