Abstract
A compact steam cooking unit includes a compartment for holding fresh or frozen food to be cooked by steam and an associated gas-fired generator of steam which are combined in a fully self-contained appliance which requires only conventional utility connections and can be mounted on a counter-top. The steam generator includes a powered burner firing into one or more fire tubes which are submerged in water which is maintained at a desired level in a water chamber. Steam derived from heating of the water passes from the water chamber through ports into the cooking compartment where it contacts the food to be cooked.
