Whipped Turnips with Bacon and Caraway

Preheat oven to 350 degrees F. Butter a 13 x 11 in. gratin dish. Place turnips in a pot and add water to cover. Heat to boiling over high heat. Reduce heat and simmer until very tender, 25 to 30 minutes. Drain turnips well and place in a mixing bowl. Beat turnips with an electric mixer. Add the butter and sour cream and continue beating until the mixture is fluffy but still retains some texture. Beat in the caraway seeds and sugar, then season to taste with salt and pepper. Transfer mixture to the prepared dish. Chop the bacon into small pieces and sprinkle over the top of the casserole. Sprinkle lightly with paprika. (The casserole can be stored in the refrigerator at this point. Warm to room temperature before baking.) Bake the casserole until heated through, about 20 minutes. Serve hot. Makes 10 to 12 servings.
