For years I used muffin pans to bake popovers. The popovers came out okay, but the cups in a muffin pan are not as deep as the cups in a popover pan. Several years ago, a friend gifted me with a Chicago Metallic 6-cup Popover Pan. I loved it enough that I purchased a second one from Amazon.
Usually I bake regular popovers, which are basically made from eggs, milk, and flour. I love apples and baking with them. So I thought popovers made with a diced fresh apple would taste great. And I was right! This treat immediately became a family favorite.
