For the next thing I decided to cook in the annoying pan, I made an omelette. I figured, oh, this will stick for sure.
Well... it did not! Granted, I did float the omelette over a little butter on the bottom of the pan. I treated it like I was trying to make the omelette in a stainless steel pan. Put a little butter in, then pour the omelette into the puddle of butter. Easy.
And it worked for this pan too! Not a thing stuck, not even a little errant cheese sticking out of the omelette.
