Maybe I over-looked it, but I don't think anyone has mentioned twice baked potatoes. They are a Christmas and Thanksgiving treat for us.
We make them by scooping out baked potatoes, mashing and mixing with butter, sour cream, chives, S&P, then stuff the shells and top with good cheddar cheese and a dusting of paprika. Cover with foil and bake at 350 until hot, then uncover and bake a little longer to crisp the top.
Sometimes I sprinkle a few bacon bits on with the cheese.
I love love twice baked sweet potatoes, too. I use butter in them, then top with some diced apples or drained, crushed pineapple and a sprinkle of cinnamon.
We get by with a little help from our friends
