I cook in my teflon wok pans all the time. I recently saw an answer here suggesting to preheat a pan to a high temperature and cook in small batches when preparing stir-fry food. I would like to try that, and several other things like roasting peanuts or spices. However, I know that teflon pans do not handle high heat well.
I do not want to ruin my pans and I prefer to err on the side of caution, but I think that maybe some of my dishes could taste better if I preheated the pan to a higher temperature than I do now. I'm afraid that I will overdo it though.
How do I preheat a teflon pan without having to worry about overheating it? Is there a technique that would help me find the sweet spot?
