I have a friend who says he can tell what type of oven a pizza was cooked in by the look and the smell of the pizza. I love pizza, and some are better than others, but I can't always say what makes one better. I definitely can't tell you what type of oven my pizza was cooked in.
My friend says that electric ovens, even the ones used at restaurants, can't get the pies as crispy. However, I have heard that the electric ovens are much easier to use, so I guess that's why some businesses use them. For me, I think one of these counter-top electric ovens would be fine. I doubt I could tell the difference.
