Why food sticks - egg test
Pour cooking oil down the sides, so it flows to the center, then swirl it around.
If you don't heat the wok before you start cooking, the non-stick properties of the surface will not be activated
If you do not warm the wok before start cooking, the surface will not have non-stick properties. Food will stick during cooking.
The pre-heating temperature becomes less critical over time. The more often and the longer you use the wok, the more effective the non-stick properties will be, and less oil will be required.
