A cast iron wok is a versatile cooking vessel known for its excellent heat retention and even cooking. Made from cast iron, it can withstand high temperatures, making it ideal for stir-frying, searing, and deep-frying. The material also develops a natural non-stick surface when seasoned properly, enhancing its cooking performance over time. These woks are often heavier than their non-stick counterparts, providing stability during cooking. They can be used on various heat sources, including gas stoves, electric stoves, and even in the oven. With proper care, a cast iron wok can last for generations, making it a valuable addition to any kitchen.
