Oil Never underestimate the role oil plays in successful stir-frying.
Here are some important tips to follow. Never use any toasted oils, such as sesame, for stir-frying because they are unstable at high temperatures. My personal favorite is olive oil, although peanut, safflower and soybean oil are also good choices. After you place oil in the wok, gently swirl it around to coat the sides. This will prevent food from sticking to the sides as you stir.
