Query: I have no use for these.

It's such a great idea, right? Don't have to really worry about getting the pan all stained and dirty, and the food won't stick! But, I've found that there's a limited amount of things I can use the silicone baking mats for. Anything I use them with comes out soft and chewy, which is nice for some things, but I usually like the cookies I bake to have just a little bit of crispiness around the edges. I used these once, and they've been in my pantry ever since.
