You need to make a pan of buttermilk biscuits or a skillet of hot cornbread just so you can try this very creamy and very buttery Whipped Sweet Potato Butter. The recipe not only makes a lot, but the butter freezes well. Simply roll the butter into a log in parchment paper, wrap in plastic wrap, then aluminum foil, and freeze. Cut off pieces as you need them like it was a regular stick of butter. It pairs perfectly with our Cheddar-Caramelized Onion Bread.
