While I do like cast iron a lot - one can fry with stainless without food sticking.
There are a lot of instructions online with you tube vids as well… basically you get the pan hot (I usually use a med high heat at first) test with a few drops of water and when they sizzle away then the pan is hot enough.
Now is the time to add a small amount of oil. I will usually turn down the heat to medium and add about a tablespoon or less of oil. The oil is ready when you can see a bit of smoke coming off it. Add your meat or food and cover. Let it sit for a minute or two depending on the thickness of the meat. Giving the pan a little shake should loosen the meat when that side is done. It might need a little nudge with a fork but then slide easily and turned over… if the pan has completely dried of any oil then a small amount may be added before adding the meat.
I have made pancakes on stainless without any sticking using this method so it is possible to cook without non-stick cookware and not use cast iron. Just be careful with your heat and keep it as low as possible.
I have this set or one similar bought from Woot about a year ago.
