Iron plates are used over an open flame or electric stove element, and retain heat longer than other metals. Aluminum is more easily malleable and an efficient heat conductor, used for both stovetop and electric makers. After seasoning, it becomes virtually non-stick. Non-stick coatings are applied over aluminum, do not require seasoning, and are easy to clean, so they cater to our desire for convenience. Old timers who have used iron and aluminum makers miss the extra flavor from the seasoned plates that is missing from nonstick makers.

Belgian waffles, or Belgian cookies, are a generous pastry, usually about an inch thick. Their many deep indentations can hold a lot of syrup or melting ice cream.
Belgian cookies are also generally known as gaufrettes, galettes, and stroopwafels.
