You can use a non-stick, stainless steel, or carbon-steel pan or wok. If you are using a non-stick pan, avoid preheating it without food on it. You should also never use it on high heat because it can damage the coating and cause the release of harmful toxins to humans and pets. If you are using a stainless steel pan, make sure to preheat it first before adding oil to prevent food from sticking.
