Waffles. There are two types of waffles commonly available in Belgium: the Brussels waffle and the Liege waffle. The Brussels waffle is rectangular with deep pockets and is dusted with confectioner's sugar. The Liege waffle, on the other hand, is more irregularly shaped, and is made with chunks of sugar that caramelize on the outside as the waffle cooks. Both kinds are often eaten as a snack food in Belgium, and can be bought on the street from street vendors.
