Pre-heat your pans or skillets on medium high for 3-5 minutes before putting oil or fat in it (NO cooking spray), then give it 30 seconds for the fat to heat before putting meat or anything else in it to dry or saute. That is all it takes.
And yes, don't buy the cheap stuff, the better quality will last you a life time.
I have a set of copper bottom Revere ware from the early 1950s and they are still like new, except Paul Revere's portrait has disappered(worn off from long use and polishing after every use). Also have a few pieces of Calphalon stainless that was still made in the USA and like it very much. NO non stick cookware for me. You don't see any of it in commercial kitchen and should tell us something.
If yu accidentally burn something and it is really stuck bad, get a box of Arm & Hammer Washing Soda. Put a heaping TBsp full i the pan, fill with hot water and let soak over night. Works every time.
But do oit use the soda on anything but stainless or glass.
