Good Morning Neil,
A waffle is kinda/sorta like a pancake but made in it's own cookware called a waffle iron. I usually add pecans. You can make them savory as well.
I tried to link you to a photo but it looked weird when I pasted it. If you will google an image of a waffle, it will show you the waffle and the waffle iron.
Even though I have read to beat the egg whites for pancakes or waffles, I don't remember ever doing so.
I've only done it for meringue.
