Abstract
Abstract An electrical cooker for cooking poultry eggs in their shells without water comprises an open-topped cooking chamber with a radiant electrical heating element and a holder for an egg which is arranged to be inserted into the chamber through the open top. The holder comprises a part which forms a closure for the chamber and three or more depending fingers which are spring-loaded towards each other and arranged to hold an egg between them. Above the closure part is a manually operable button depression of which opens the fingers apart from each other to allow an egg to be inserted between them or to allow a cooked egg to be deposited by the holder into an egg cup. Preferably the cooking chamber is of upwardly tapering truncated conical shape and the heating element is ring-shaped and is in the lower part of the chamber where it surrounds the lower part of the egg while it is being cooked.
