Liege Waffles (Belgian Pearl Sugar Waffles)

I have not yet had the good fortune to visit Belgium, but I do frequent a lovely NYC cafe called Le Pain Quotidien, which is based in Belgium. I tried their crispy, caramelized Belgian Sugar Waffle, and was instantly in love. If perled sugar is not available, substitute an equal amount of coarsely crushed sugar cubes. I got this recipe off a Belgian website.
