My favorite mashed potato is a bit unconventional. I bake the potatoes, and when they are done I slit them open on the top, mash the potato within the skin with a fork and add butter, salt and eat it.As a bonus, after the inside potato is eaten, you have the remaining skin which is delicious with sour cream. I have never tasted a better mashed potato.
