Abstract: An apparatus defining a baking pan, including a planar floor, with a surrounding water chamber mounted about the floor defined by coaxially aligned internal and external walls, with a fill-spout cooperative between the walls to effect filling of the defined chamber by a fluid such as water. Modifications of the instant invention include the chamber open at its upper end defining an annulus cooperative with a lid defined by a complementary annulus aligned with the lower chamber to permit directing and circulation of steam in cooperation with the lower chamber. The modification further includes a downwardly depending externally threaded skirt cooperative with an internal threaded interior wall of the pan.
