So I'm in the market for new cookie sheets, and I'm willing to spend for high quality ones that will last. Any suggestions, anyone? Any specific brand anyone likes? Bad experiences with other brands? Do you prefer ones with a lip on one side, no rim at all, or a jellyroll pan? What about the finish - aluminum, non-stick, insulated...? I don't know if it makes a difference or not, but I much prefer cookies that are chewy/cakey as opposed to crunchy. I appreciate any input anyone has!
