I wanted to use this for a flax bread recipe because my spouse is allergic to wheat and yeast, and the recipe I found suggested using parchment paper or a silicone mat. I bought this one after reading some good reviews, and it seems to perform as expected. It arrived rolled up in a tube, and after a quick wash, I molded it into a 10x15" cookie sheet (you can trim it if you want, but I didn't want to), and spread the flax batter. The final result did not stick at all, although the bottom of the bread is not crispy as might be expected from cooking on a standard pan. There was no unusual smell or taste imparted in the final product, unlike some other mats I've read about, and cleanup is a snap. Hope to test it out on some wheat-free cookie batter next.
