The long handles are used to open the mold and then hold it over a fire. Considerable skill is required to know when to put the dough into the mold and when to take it off the fire. After years of practice, I now only burn about 10% of the pizzelle that I attempt. In the case of waffles, electric technology is much better, and we shall move to that forthwith.
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.
