These pans required "seasoning" prior to use, which was a breeze. We simply followed the directions provided in the packaging.
I am so glad we got these pans. They do not use Teflon or some such material to induce non-stick. These are naturally non-stick.
I have used these pans a bunch of times so far and I love 'em. The conduct heat uniformly and nothing sticks to the pans. Cleaning the pans is a breeze as well.
One requirement is that after you wash and clean the pans, you put a coating of oil on them. Piece of cake, ya know?
