Abstract
An insulated cooking utensil has upper and lower substantially planar sheet members secured together with an air chamber interposed therebetween for insulating the upper sheet member from direct heat during cooking. Spaced detents are provided in the lower sheet member to support and maintain the upper and lower sheet members in a spaced relationship. The detents have dome-shaped configurations with relatively large dimensions and a flat spot at the peak to prevent deforming the upper sheet member locally where the detents contact the upper sheet member during use. The upper sheet member is made of aluminum and has a clear anodized coating on its upper surface. An angular disposed flange with an elongated thumbgrip extends along one side of the cooking utensil to facilitate gripping and handling. An expansion space between the outer edges of the sheet members accommodates a relatively greater expansion of the lower sheet member during cooking.
