A stovetop waffle maker is essentially a hinged pair of cooking plates that fasten together. To cook waffles, you put the batter inside the waffle maker and put it on the stove, flipping it over to cook both sides. This was how people cooked waffles before electric waffle makers existed, and some people who grew up making them this way may prefer a stovetop model.
Recipes for both Waffles and Fried Chicken appear in What Mrs. Fisher Knows About Old Southern Cooking, (Abby Fisher, 1881). Mrs. Fisher was a former slave and her book is generally considered the first cookbook written by an African-American. Apparently, white people were eating waffles and fried chicken as well as recipes for the two appear in Mrs. Porter's Southern Cookery Book published in 1871.
