Typical American waffles (often referred to as the so-called Belgian waffles that you can get anywhere in the U.S.) are made with a batter that is poured into a waffle maker. Liège waffles are made from a rich, yeast-based brioche dough that raises for an extended period of time to develop a unique flavor, then has Belgian pearl sugar kneaded into it before cooking each waffle in a Belgian waffle iron.
