Abstract

The method and apparatus for preparing foodstuffs by boiling and/or steaming including a thin walled and, hence, crushable insert having water-tight properties and mounted within a porous structure providing support for the thin walled insert, and holding the insert in a spaced fashion relative to the bottom and side walls of a cooking vessel, thereby forming the equivalent of a heat pipe structure in the hollow gap space between the insert support and the cooking vessel. For foodstuff preparation by boiling, water may be added to both the vessel interior and the insert interior, the foodstuffs being placed within the insert. The insert may be provided with a lip bridging the aforesaid gap to facilitate filling or emptying of the insert without spilling the insert contents into the vessel, thereby keeping it substantially clean. The aforesaid lip may completely surround the insert and overlie the gap, suitable openings being provided to permit the escape of steam therethrough. The vessel may be employed with steam generating apparatus provided either independently of or in combination with heating apparatus such as the hot plate, for example.
