Oops - I scratched it like the booklet says not to. I was cutting the bread, didn't realize the paddle was in the bottom of the bread, and I put a nice little knife slit on the paddle! The booklet thing I got with it says not to scratch it... anyone know why? It's only a non-stick surface right? Now that part won't be non stick right? I guess if a ball of dough is rolling around in it, it might get caught on the part that's scratched.... crap.
