Energy comes from USDA nutrient 1008. Salt is calculated as sodium × 2.5, with unit conversion to grams. It is not a separately measured salt value.
Preparation
Butter is about 81% fat and 717 kcal per 100 g; the rest is water and milk solids. In a pan the water boils off and the solids brown, so browned butter is slightly more concentrated but carries the same calories. Clarified butter and ghee, with the water removed, run close to 900 kcal per 100 g. Whatever stays in the pan and is poured away is the only reduction.
Logging this food
A tablespoon is 14 g and 102 kcal; a pat (5 g) is 36; a stick 113 g, 810 kcal. The usual under-count is the butter that "cooks off" — it does not. If you fry in a tablespoon and eat the eggs with the pan scraped, log the tablespoon. Salted and unsalted are identical in calories.
Swaps and alternatives
Olive oil is not lighter — 884 kcal per 100 g and 119 per tablespoon — but a spray or a teaspoon (40 kcal) can replace a tablespoon in most pans. Light spreads (about 40–60% fat) roughly halve the calories per gram. Mashed avocado on toast is about 160 kcal per 100 g against butter's 717.
