There are millions of recipes for waffles, but most batters fall into two distinct categories: yeast-raised (more commonly used for thicker Belgian-style waffles) and baking powder-leavened (also called "American"; think Bisquick and the like). That said, you can use yeast-raised batter in American-style waffle makers and American-style batter in Belgian-style waffle makers—the results will just be a little different than usual due to the differing shapes and sizes. Our lineup of contenders included both Belgian- and American-style machines, though for the sake of simplicity we eliminated "flip-style" models. (They tend to take up more space than other waffle irons and a perusal of anecdotal reviews indicated that they didn't perform any better.) We tested all of the machines using this crispy waffle recipe, minus the caramel coulis.
Like most electric waffle irons, the Cuisinart WMR-CA waffle maker isn't meant to be submerged, and the waffle plates are built right into the machine, so you can't remove them for a good scrubbing. Surprisingly, removable plates are relatively rare, especially in the American/traditional waffle maker category. But the Black and Decker G48TD (Est. $40) has them, which makes it very convenient to use. Not only do the non-stick waffle plates pop out for easy cleaning, they also have a completely flat reverse side (also non-stick). Flip the plates to their flat side and open the G48TD's lid all the way, and you have yourself a mini griddle for cooking things like pancakes and bacon; or close the "floating" hinged lid and use it to toast sandwiches.
