The decorative serving casserole is perfect for presenting small dishes, sauces, or accompaniments. The casserole is made of copper and stainless steel. Copper is an excellent heat conductor and keeps the contents at the right temperature. The stainless steel on the inside allows the use of metal utensils, such as for stirring sauces before serving, without damaging the coating. Please note that the casserole is intended for serving only and should not be used for cooking.
