How to choose the right cast iron wok? If you’re using it for induction cooking, choose a flat-bottomed wok for a more direct stovetop contact. Cast iron wok comes with a bit of weight, and a pan with two side handles will help you lift it with ease. Wrought iron woks are significantly lighter though but have the same cast-iron cooking abilities, which works for home cooks with smaller hands. As for size, a 30cm wok is good for two while a 35cm wok can serve up to four.
