After a lifetime of nonstick baking sheets, I was persuaded to try this basic metal jelly roll pan with a parchment liner instead. The difference is incredible! It may be called a "jelly roll" pan, but I can bake upwards of a dozen cookies on it and rarely burn one. With the old nonstick sheets (of which I tried and discarded several brands over the years)the burn rate was more like 25-50%. Other uses for this sheet are under other open dishes, like casseroles and pies, for catching the drips and runovers -- the raised sides make this possible.
Using a sheet of parchment paper or a silicone mat, cleanup is a snap. Once in a while it doesn't hurt to handwash to remove accumulated residue on the edges, but it takes a lot of baking before that becomes an issue.
This pan will occasionally warp at the higher temperatures, but always snaps back as it cools down. I don't think I've come across a baking sheet yet that hasn't done that at one time or another, so it probably just comes with the territory.
It looks like I am done with forever replacing my scratched cookie sheets!
