Liege waffles are even more robust than a traditional Belgian waffle. They are thicker and tougher, and not that perfectly shaped. Their texture is similar to that of breads, as they are made using yeast dough instead of traditional a batter. They are thus not as airy or lightly textured as the Belgian or even the American waffles. However, their taste is often described as intense, and they boast of pearl sugar, which are like sugar bullets added into the dough. Upon cooking, these sugar pearls melt and caramelize, adding a whole new dimension to waffles- both in means of texture as well as flavor.
