The SimmerMat is a heat diffuser that is used on low heat settings, to provide perfect heat control for low and slow cooking. The SimmerMat heat spreader is placed between the pot of food and the heating surface to provide temperature control in simmering and slow cooking. With the SimmerMat, hot spots are eliminated so food will not stick, scorch or burn. Our electric burner covers are terrific for soups and casseroles, rice and oatmeal, milk desserts and sauces, melting chocolate and toffee, chutney, pickle and relishes, and hot drinks. Our flame reducer can be used in place of a slow cooker, double boiler, or rice cooker. Our flame defuser can be used on all cooking surfaces, electric coil, gas burner, and glass cooktops. Our flame difuser allows for use of clay and glass cookware on induction cooktops.
