rasvakeitin

A rasvakeitin, also known as a fat separator or gravy separator, is a kitchen tool designed to separate fat from liquids, most commonly used for meat juices or gravies. It typically consists of a pitcher or container with a spout positioned above the bottom.

The principle of operation relies on the difference in density between fat and liquid. When a hot liquid, such as meat drippings, is poured into the rasvakeitin, the fat, being less dense, will rise to the top. The spout is strategically placed just below this surface layer of fat. By tilting the rasvakeitin, the lower liquid layer can be poured out, leaving the accumulated fat behind.

These devices are often made of heat-resistant materials like glass or plastic. Some models may include a lid to prevent spills or retain heat. They are particularly useful for preparing healthier versions of dishes by reducing the fat content of sauces and gravies. After use, a rasvakeitin can usually be cleaned with soap and water, and many are dishwasher-safe.
