My wife got me a Weber porcelain enamel coated cast iron griddle for my Genesis E-320 grill for my birthday today. I've been cooking Sunday breakfasts on an electric griddle lately, and I can't wait to do it on the grill. I've seen some reviews saying that food sticks pretty badly. Anyone here have one of these? Suggestions for use to avoid sticking? Ideas of things to cook on it other than breakfast foods?
