The Le Creuset Marmite Casserole 32 cm Matt Black extends wide from below, just like with a wok. This brings the heat more to the side of the pan for better heat distribution. You can make delicious stews for about 7 people in the casserole. Ideal when you like to dine with friends, have a large family or cook directly for several times. Saves work next time. The frying pan is made of durable cast iron material, so that the heat build-up and distribution are even. You wash the pan by hand and if you maintain it properly, you will enjoy it for years and maybe even generations.
