Butter - online puzzles

Butter is a dairy product containing up to 80% butterfat (in commercial products) which is solid when chilled and at room temperature in some regions, and liquid when warmed. It is made by churning fresh or fermented cream or milk to separate the butterfat from the buttermilk. It is generally used as a spread on plain or toasted bread products and a condiment on cooked vegetables, as well as in cooking, such as baking, sauce making, and pan frying. Butter consists of butterfat, milk proteins and water, and often added salt. Butter may also be sold with added flavourings, such as garlic.

Most frequently made from cow 's milk, butter can also be manufactured from the milk of other mammals, including sheep, goats, buffalo, and yaks. Salt (such as dairy salt), flavorings and preservatives are sometimes added to butter. Rendering butter, removing the water and milk solids, produces clarified butter or ghee, which is almost entirely butterfat.

Butter is a water -in- oil emulsion resulting from an inversion of the cream, where the milk proteins are the emulsifiers. Butter remains a firm solid when refrigerated, but softens to a spreadable consistency at room temperature, and melts to a thin liquid consistency at 32 to 35 °C (90 to 95 °F).
