Most commonly, popovers are made and eaten as plainly as they are with just five ingredients. As I said earlier, the recipe is malleable so that it can be tweaked to later the flavor. When I was digging looking for that old recipe I used to make every Sunday for 10 years, I discovered so many different flavors of popovers. I saw sweet cinnamon and sugar popovers, prosciutto and cheese popovers, cranberry popovers; you name it and it’s been made!
