This Swedish potato side dish is perfect for the holidays. Quick and simple starchy potatoes, thinly sliced and brushed with a spicy, earthy butter sauce. The skin of the potato crisps up during the cooking process and keeps the butter sauce from drowning into the soft center of the potato. Remember not to cut through the whole potato, stop about halfway down for a perfect fanned out look. Sprinkle a little salt and pepper over top for the finishing touch.
