A blue and cream 20cm, or golden yellow and cream 22cm enamel omelette pan suitable for all heat sources, even induction. Perfect omelettes every time! From the Riess enamel works in the Austrian alps, which drawing power from its own hydroelectric plants, provides a model for sustainable industry. 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.
