Oils & FatsYear-round, though butter from grass-fed cattle exhibits more pronounced flavor and deeper color during spring and summer months when fresh forage is available.

Rich in fat-soluble vitamins A, D, E, and K2, particularly in butter from grass-fed sources; contains butyric acid, a short-chain fatty acid with potential metabolic benefits.

About

Butter is an emulsified suspension of water, milk solids, and butterfat obtained through the churning of cream (the fatty portion of milk). Traditionally produced from dairy cream, butter consists of approximately 80-82% butterfat, 15-17% water, and 1-2% milk solids, with the exact composition varying by production method and source milk. Unsalted butter, also called sweet butter, contains no added sodium chloride, allowing the natural dairy flavors and the cook's control over seasoning to predominate. The color ranges from pale yellow to deep golden depending on the breed of dairy animal, their diet, and the season of production.

Culinary Uses

Unsalted butter serves as a fundamental cooking fat across cuisines, providing emulsification, tenderness, and rich flavor to baked goods, sauces, and sautéed dishes. It is essential in French cuisine for beurre blanc, beurre noisette, and countless pâtisserie applications, where precise salt control is critical. In baking, butter contributes to the structure and texture of pastries, cakes, and cookies; in cooking, it serves as a medium for flavor development through browning and as a finishing enrichment for sauces and vegetables. Its lower smoke point (approximately 350°F/177°C) makes it suitable for medium-heat cooking and finishing rather than high-temperature frying.

Forms & Preparations

Unsalted block/stick — Standard form sold in 1/2 lb (227 g) or 1 lb packages; cut into portions as needed for cooking and baking.
Cultured butter — Cream fermented before churning, yielding tangy flavor; 1:1 substitution in recipes.
Browned butter (beurre noisette) — Heated until milk solids caramelize, producing nutty aroma and flavor; used as a finishing fat for pasta, vegetables, and baked goods.
Clarified butter (ghee) — Water and milk solids removed through gentle heating and straining, leaving pure butterfat; extended shelf life and higher smoke point.
Compound butter (beurre composé) — Softened butter mixed with herbs, spices, or other flavoring ingredients; served as a finishing pat on proteins or vegetables.
Cultured clarified butter — Clarified butter made from cultured cream, combining the tangy notes of fermentation with the purity of ghee.
