Food Sticking To Non-Stick Waffle IronI bought a new non-stick waffle iron, and since "non-stick" doesn't always mean that, I preheated it and brushed oil on it, as the manual said to do. Well, we all know what happened, right?! Stuck all over the place. I know not to spray Pam, etc. on non-stick. It's the kind that beeps when the waffle is ready, so I know I didn't open it too soon. Please help!
