oz/250 g butter

Butter is a dairy product produced by churning cream or milk to separate the butterfat solids from the buttermilk. It consists of at least 80% milk fat by weight in most culinary standards, with the remainder composed of water and milk solids. The fat is derived from the homogenization and mechanical agitation of cream, causing the fat globules to coalesce into a solid or semi-solid state. Butter is typically pale yellow to deep golden in color, depending on the diet of the dairy animals and the season of production. The flavor profile ranges from mild and sweet to rich and nutty, with variations influenced by the cream's freshness, pasteurization level, and aging period. Cultured butter, made from fermented cream, develops a more complex, slightly tangy character, while sweet butter is produced from fresh, unfermented cream.

Butter serves as a fundamental cooking fat and flavor base across global cuisines, essential in baking for creating tender crumbs and laminated doughs, and indispensable in sauces for emulsification and richness. It is used for sautéing, pan-frying, and finishing dishes, where it adds depth and glossiness. In pastry work, cold butter is incorporated into doughs for croissants, puff pastry, and pie crusts to create distinct layers. Clarified butter (ghee) is preferred in Indian, Middle Eastern, and Southeast Asian cooking for its higher smoke point and extended shelf life. In French cuisine, beurre blanc and beurre noisette (brown butter) are classic preparations. Compound butters—mixed with herbs, spices, or other ingredients—serve as elegant finishing elements for grilled meats and vegetables.
