g/2½oz butter
Rich in fat-soluble vitamins A, D, E, and K2 (particularly in grass-fed varieties), and provides butyric acid, a short-chain fatty acid with potential digestive benefits. Butter is calorie-dense and primarily composed of saturated fat.
About
Butter is an emulsified dairy product produced by churning cream or milk to separate the butterfat from the buttermilk. Originating in ancient cultures and refined into its modern form across Europe, butter consists of approximately 80-82% fat, 15-17% water, and 1-2% milk solids. The flavor and color vary by source: grass-fed butter tends toward deeper yellow and richer, more complex flavor, while grain-fed butter is typically paler and more neutral. Cultured butter, made from fermented cream, develops tangy, nuanced notes valued in European baking and cooking traditions.
Butter's composition—primarily saturated and monounsaturated fats—creates its distinctive plasticity at room temperature and its capacity to brown and caramelize, developing nutty, toasted flavors through the Maillard reaction.
Culinary Uses
Butter serves as a fundamental cooking fat and flavor foundation across global cuisines. It is essential in baking for creating tender crumb structures and laminated doughs (croissants, puff pastry, Danish); in sauce-making for emulsification and richness; and in sautéing and finishing dishes for depth and gloss. French cuisine relies heavily on beurre blanc, beurre noisette (brown butter), and compound butters; Indian cooking uses ghee (clarified butter); and countless traditions employ butter as a cooking medium and enriching agent. Melted or softened butter also functions as a basting agent, spreads, and the foundation for sauces.
