By the 16th century, paintings by Joachim de Beuckelaer, Pieter Aertsen and Pieter Bruegel clearly depict the modern waffle form. Bruegel's work, in particular, not only shows waffles being cooked, but fine detail of individual waffles. In those instances, the waffle pattern can be counted as a large 12x7 grid, with cleanly squared sides, suggesting the use of a fairly thin batter, akin to our contemporary Brussels waffles (Brusselse wafels).
A waffle is a dish made from leavened batter or dough that is cooked between two plates that are patterned to give a characteristic size, shape, and surface impression. There are many variations based on the type of waffle iron and recipe used. Waffles are eaten throughout the world, particularly in Belgium, which has over a dozen regional varieties. Waffles may be made fresh or simply heated after having been commercially precooked and frozen.
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.
