Abstract
A utensil for heating circular elongated objects with microwave energy is disclosed for securing browning and searing of the exterior surfaces. A plurality of searing members of a curved tapered substantially V-shaped configuration encompass a portion of or all of the elongated object to be heated. The searing means are supported on a microwave transparent frame of a plastic material.
Claims3
An apparatus for heating circular elongated objects with microwave energy comprising:
- a plurality of curved conductive members surrounding a substantial portion of the objects to be heated;
