Butter

Butter: Butter is a fatty substance (82% fat) obtained by churning the cream of milk, then washed and kneaded to make it smooth. Butter hardens in cold and liquefies in heat. Its color varies from creamy white to golden yellow, depending on the diet of dairy cows (rich in carotene in pastures). Nowadays, in France, you can also find sheep and goat butter.
