I discovered this recipe in Lee Lee's Recipe Box. The description to the recipe reads as follows: "These Giant-Size Popovers are made in individual containers to allow lots of room for rising. They can be filled with creamed ham, chicken, or seafood and served as a main dish, or they can be served piping hot with plenty of butter." Be sure when you make these to spread the custard cups out. These babies puff up pretty big ; ) I hope you will enjoy them!
