Bodum makes its Maestro wok out of cast iron, so it works beautifully on gas, ceramic and electric stovetops, and is a superb cooking tool for induction stoves, too. And with its distinctive shape and colorful enamel exteriors, it also looks great.The unique heat conduction characteristics of cast iron keep a constant heat at any stovetop setting and the matte enamel cooking surface means you can cook with very little oil. The Maestro wok measures 14.5" in diameter and comes with a steel steaming/warming rack and a solid glass lid, so you can see what's cooking. Please hand wash.
