A method of removing an immiscible liquid having a given density from another liquid having a different density, such as removing fat floating on hot soup. A flat thermally conducting plate 14 is cooled to a temperature below that at which the fat solidifies and is lowered onto the floating fat to cause it to congeal and adhere to the under surface of the plate. The plate 14 may be the base of a vessel 10 cooled by placing a solid, having a freezing point similar to the soup, within the vessel. Preferably the solid is ice formed into cubes. Also disclosed is a separate invention to an apparatus comprising a vessel characterised by a an outside less thermally conducting than the base or the vessel comprising a base with an edge that does not flare out on its way up. |
