Introduced in North American in 1962, Belgian waffles usually use a yeasted batter that results in a waffle that rises, making them thicker and softer than American waffles -- although they should still be crispy on the outside. They're larger too, which is why they need a different type of waffle maker than traditional, American-style waffles. The deeper pockets on Belgian waffles are great for holding toppings like syrup, whipped cream or fruit.
That said, quite a few users say that this waffle maker isn't as sturdily built as previous versions of the same model, and that if you don't get the top heating plate aligned just right, it can fall off -- an injury hazard if the plate is hot. The top of the G48TD also gets very hot. Some use pliers to bend the metal clips that hold the heating plates in place, which helps them line up better -- or you can just use an oven mitt to protect your hands.
