Tried this tonight. What a great idea to dress up a baked potato. Yummy. The Perfect Baked Potato. Slice potato almost but not all the way through. Tuck butter between slices. Bake until tender. Dribble with sour cream. Shower with grated cheese. Bake again until melted and gooey. Lavish with more sour cream and chopped scallion or crumbled bacon or chili or whatever you please.
