Calories in Butter, stick, salted
Butter is not pure fat — it's a water-in-oil emulsion that's roughly 18% water trapped inside a continuous fat matrix.

What makes butter so powerful?
Cream starts as an oil-in-water emulsion: microscopic fat droplets suspended in water. Churning physically damages the membranes surrounding those droplets, causing them to coalesce until the entire system flips — the phases invert, and water becomes trapped inside a continuous fat network. That's why butter is only about 80% fat, not 100%. The remaining ~18% is water, with small amounts of milk proteins and lactose. The characteristic golden-yellow color of butter from grass-fed cows comes from beta-carotene in fresh pasture. Cows convert beta-carotene into vitamin A inefficiently, so the excess accumulates in milk fat. In winter, when cows eat dry feed, butter is naturally paler. Salt is added at roughly 1–2% by weight, serving double duty as a flavor enhancer and a preservative that inhibits microbial growth in the dispersed water droplets.
Phase-inverted emulsion
Churning flips cream's oil-in-water structure into butter's water-in-oil matrix, trapping moisture inside fat.
Yellow from beta-carotene
Grass-fed butter's golden hue comes from beta-carotene that cows cannot fully convert to vitamin A.
Salt as preservative
The 1–2% salt content inhibits microbes in butter's water phase, extending shelf life beyond unsalted butter.
💡 When & how to use it
Use salted butter for finishing — spreading on bread, melting over hot vegetables, or basting pan-seared meats — where its seasoning and dairy flavor are meant to be tasted directly. Avoid it in baking when precise salt control matters; opt for unsalted instead. Store refrigerated for up to a month or frozen for several months, wrapped tightly to prevent absorption of odors. The milk solids in butter begin to brown around 150°C (300°F), producing nutty browned butter — ideal over pasta or fish — but for high-heat searing, choose a clarified fat instead.
