During the olden times, my grandmother used to rub salt on her frying pan so 
food wouldn't stick.
 
When i use vision or corningware's pyroceram cookware, or stainless steel 
frying pan, I add a paper thin slice of butter to my cooking oil and my food 
never sticks.  Always worked.  You don't need a lot of butter to make it work.
