Butter is commonly sold in sticks

Butter is a dairy product made by churning fresh or fermented cream or milk. It is an everyday food in many parts of the world. Butter consists of butterfat surrounding minuscule droplets consisting mostly of water and milk proteins. Butter from cow's milk is most common, but butter is made from the milk of other mammals as well, including sheep, goats, buffalo, and yaks. Salt, flavorings, or preservatives are sometimes added. Butter is used as a condiment and in cooking applications including baking, sauce making, and frying. Butter can be rendered to produce clarified butter or ghee, which is almost entirely butterfat. Butter is a firm solid when refrigerated, softening to a spreadable consistency at room temperatures. Butter's color is generally a pale yellow, but can vary from deep yellow to nearly white. The color of the butter depends on the animal's feed and is sometimes manipulated with food colorings, most commonly annatto or carotene. (more...)
