Enamel frying pans with black interiors and variously red, blue, or yellow exterior sides. With beech handles to keep fingers cool. Powered by their own hydroelectric power plants, carbon neutral Riess provide a model for environmentally responsible industry. Tracing their roots back to 1550 they are also proud of their tradition for excellence. Each size is a different colour, the red having a diameter of 20cm; the blue, 24cm; and the yellow 26cm. By tradition pan sizes equal the diameter across the top and not of the base. This might seem a cheat to some (or perhaps not if you consider a wok) but after some consideration we thought it best to stick with standard practice. PLEASE NOTE THE LARGES PAN NOW IS GREEN RATHER THAN YELLOW.
