Abstract
Abstract The invention relates to a method of cooking or reheating a comestible with microwave energy by utilizing a double-boiler cooking utensil. The double-boiler utensil contains a microwave susceptible liquid within an outer vessel and a cooking oil or fat within an inner vessel with the inner vessel providing conductive heat transfer between the microwave susceptible liquid and the cooking oil or fat. The process involves placing a comestible in the cooking oil or fat within the inner vessel and irradiating the cooking utensil containing the comestible for a period of time effective to cook the comestible. The microwave susceptible liquid when subjected to microwave energy functions to transfer sufficient heat to the cooking oil or fat to maintain a temperature on the surface of the comestible within the range of from 125° C. to 225° C.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
147 words
A method of cooking or reheating a comestible with microwave energy which comprises: (a) placing a double-boiler cooking utensil in a microwave oven, said utensil containing a microwave susceptible liquid in an outer vessel and a cooking oil or fat within an inner vessel wherein the walls of the inner vessel provide conductive heat transfer between the liquid and cooking oil or fat; (b) inserting a comestible which is to be cooked or reheated into the cooking oil or fat within the inner vessel; and (c) irradiating the comestible with microwave energy for a period of time which is effective to cook or reheat the comestible, said microwave susceptible liquid being effective to transfer sufficient heat to said cooking oil or fat to maintain a temperature on the surface of the comestible in the range of from 125° C. to 225° C. during irradiation with microwave energy.
Claim 2
Independent Claim
147 words
A method of cooking or reheating a comestible with microwave energy which comprises: (a) placing a double-boiler cooking utensil in a microwave oven, said utensil containing a microwave susceptible liquid in an outer vessel and a cooking oil or fat within an inner vessel wherein the walls of the inner vessel provide conductive heat transfer between the liquid and cooking oil or fat; (b) inserting a comestible which is to be cooked or reheated into the cooking oil or fat within the inner vessel; and (c) irradiating the comestible with microwave energy for a period of time which is effective to cook or reheat the comestible, said microwave susceptible liquid being effective to transfer sufficient heat to said cooking oil or fat to maintain a temperature on the surface of the comestible in the range of from 125° C. to 225° C. during irradiation with microwave energy.
