Oil, cocoa butter

Cocoa butter is the pale-yellow fat pressed from cocoa beans, the ingredient that gives chocolate its characteristic snap and glossy sheen and that melts right around body temperature, which is why it feels like it vanishes on the tongue. Chocolatiers melt it gently over a double boiler to temper couverture, mold candy shells, or fold it into ganache and truffle centers for a firmer set that still yields cleanly when bitten. Outside of confectionery, small amounts enrich pastry doughs, glaze cakes, or add richness to homemade chocolate bars, since it carries almost no flavor of its own beyond a faint cocoa aroma and melts cleanly rather than lingering greasy on the palate the way some solid fats do.

Look for cocoa butter sold in blocks, wafers, or buttons pressed from cocoa beans, and keep it wrapped in a cool, dark cupboard, it stays stable for months at room temperature because it is essentially pure fat with none of the moisture that spoils other ingredients or invites mold. It carries 100 g of fat and 884 calories per 100 g, so it is used in small measured amounts, a tablespoon (14 g) at a time, rather than as an everyday cooking oil poured freely into a pan. One of its few standout nutrients is vitamin E at 12% DV per 100 g, present because it is unrefined and retains some of the bean's natural tocopherols, worth remembering if it is swapped in for a neutral fat in a chocolate or confectionery recipe.
