Consistency is everything in a good dish of ice cream. Cream, milk, sugar, and vanilla in liquid form would be strange to drink, but becomes a classic dessert when churned and frozen. Ice cream machines can deliver gourmet quality ice cream for less than pricey store-bought pints, and are simple to use. Just gather your ingredients, follow the recipe for the flavor you desire, and have some sprinkles and hot fudge sauce on hand for a self-serve sundae bar. Here are our favorites.
