stoves have a tendency to stew and boil when too much food is in the wok rather than "fry" as in traditional woks, thus not producing . A wok can, however, benefit from the slow steady heating of electric stoves when used for slower cooking methods such as stewing, braising, and steaming, and immersion cooking techniques such as frying and boiling. Many Chinese cooks use Western style cast-iron pans for stir-frying on electric stoves, since they hold enough heat for the required sustained high temperatures. A newer trend in woks is the electric wok, where no stove is needed. This type of wok is plugged into an electrical outlet and the heating element is in the wok. Like stove-mounted non-stick woks, these woks can also only be used at lower temperatures than traditional woks. Induction Induction cookers generate heat in induction-compatible cookware via direct magnetic stimulation of the pan material. While carbon steel and cast iron (the most common wok materials) are induction-compatible metals, induction cooking also requires close contact between the cooking vessel and the induction burner. This presents problems with tossing techniques, where the wok is lifted off the burner and agitated, will break contact and turn off the burner. Traditionally shaped woks, which are round-bottomed, also do not have enough contact with the cooking surface to generate notable heat. Bowl-shaped induction cookers overcome this problem and can be used suitably for wok cooking in locations where gas stoves are not suitable. Flat-bottomed woks make sufficient contact to generate heat. Some cookware makers are now offering round-bottomed woks with a small flat spot to provide induction contact, with a specially designed support ring, and some induction cooktops are now also available with a rounded burner that is able to make contact with the rounded bottom of a traditional wok. In both cases, the food will need to be stirred with a cooking utensil, instead of being tossed by lifting the wok itself. Advantages The main advantage of the wok, beyond its constructed material, is its curved, concave shape. This shape produces a small, hot area at the bottom which allows some of the food to be seared by intense heat while using relatively little fuel. The large sloped sides also make it easier for chefs to employ the tossing cooking technique on solid and thick liquid food, with less spillage and a greater margin of safety. The curved
