It's my frying pan. It's black interior is now discoloured around the edge, has a different feel to it, and the last time it was used to cook bacon (albeit without oil) the bacon stuck and was ruined.
This all happened when I was making a load of tortillas in it. The pan was on for about 15 minutes or so with only tortillas on it, not on max heat, but mid-high.
Don't have a picture yet, but what do you guys think? Is it ruined, or is this reversable? I have my fingers crossed. Don't know if it will be covered in the warrantee.
