The Avanti® SimmerChef Heat Diffuser makes long, slow simmering and gentle pan frying easy. Suitable for use on any cooktop, it is ideal when making casseroles, soups, sauces, stock, custard, jam and melting chocolate. SimmerChef allows you to control the temperature of your cooking surface and replaces the need for a slow cooker, double boiler and rice cooker. Featuring 7 strategically placed cones, the SimmerChef prevents hot spots because heat is spread evenly under the base of the pot - so there's no catching, burning or spoiling and ensures long slow cooking.
