Q: Why do my baking sheets sometimes buckle in the oven? I thought they were just old and replaced them, but now the new ones are doing the same thing!

Am I going too cheap on the baking sheets or is there another reason?

Editor: Chris, we can’t speak for your current baking sheets, but our hunch is that you went with too thin sheets. You don’t need to spend a fortune, though, to get good-quality baking sheets! Look for professional, heavy-gauge aluminum sheets like these:

These last a lifetime, and can be found very inexpensively at restaurant supply stores. I have a couple of these, and they never buckle or warp. They don’t have a nonstick coating, but with baking spray or parchment I never have any problems with things sticking.

Readers, any more suggestions for Chris?
