½ cup unsalted butter

Butter is a dairy fat product produced by churning cream or milk to separate the butterfat from the buttermilk. Unsalted butter contains no added sodium, allowing cooks to control the salt content in their dishes. Butter is composed of approximately 80-82% fat, 15-17% water, and milk solids, with a pale yellow to deep golden color depending on the diet of the dairy cows and the season. The flavor is rich and creamy, with subtle dairy and slightly sweet notes. Unsalted butter is the preferred form in baking and fine cooking where salt precision is critical.

Unsalted butter is fundamental to both savory and sweet cooking across virtually all culinary traditions. In pastry and baking, it creates flakiness in pie doughs, croissants, and biscuits, and provides richness to cakes and cookies. In savory cooking, it serves as a base fat for sautéing vegetables, finishing sauces (beurre blanc, beurre noir), emulsifying pan sauces, and enriching soups and risottos. It is also used for browning (beurre noisette) to add nutty depth to dishes. The neutral salt content makes unsalted butter essential in professional kitchens and recipes requiring precise seasoning control.
