There are three main types of breakfast waffles:
Belgian: Also known as a Brussels waffle, it’s light and crispy but with deep ridges and leavened with yeast.
American: A waffle that’s been leavened with baking powder instead of yeast.
Liege: Also invented in Belgium (but predating the Belgian waffle), the Liege is made with a yeast-based dough and is softer, denser, and due to a carmelized sugar coating, sweeter.
