I'm looking at replacing most of my cookware, since it's beginning to show signs of wear. A lot of what I've been looking at is various brands of non-stick options. However, I've noticed a trend. The descriptions say to avoid cooking above medium heat. Most of the time, I do cook at medium to medium high heat, but I do cook higher when I'm doing things like boiling water.
Is medium heat sufficient to boil a water in 3-5 qt pans? I also tend to stir fry at medium-high to high heat. I've done this for both gas and electric (currently have electric) stoves.
Should I have non-stick options (like a non-stick wok for stir fry and a non-stick pot for boiling water) or am I just doing it wrong and I should be cooking more at medium or maybe medium-high heat and almost never using high heat?
