Three golden rules for using GOOD stainless steel cookware:
1. Before adding the food, put the pan on the stove to warm it before you add the oil, food, etc.
2. There is no need really to jack up the temperature much higher than medium. Ever.
3. Use Bar Keeper's Friend to wash your pots and pans. Even if they say they're dishwasher safe, wash them by hand.
If you allow the pan to heat properly before adding oil/butter or food and then don't put the heat higher than medium, you should NEVER have a problem with food sticking. Most people have sticking issues when the heat is too darn high and they try to 'flip' the food too soon, almost burning the outer layer of the food but keeping the inner layers of the food uncooked - that makes for one messy pancake! When you're cooking something that needs flipping or turning, put the item in the pan and leave it alone until it is time to flip. Unfortunately most people watch the cooking shows where the food is being jiggled, flipped, poked, prodded, slid all around the pan from the moment it is introduced...just let it sit there and cook and when it is time to flip, then flip. It'll help immensely. (*The only exception is stir frying. Stir frying should be done on high heat with everything chopped, laid out and ready before beginning the 'roller coaster' process that stir frying is. Once you start stir frying, you really can't stop the food from moving...stir frying is about the only time you really want to move the food...because you are using high heat)
