Recipe: Buttermilk-Plum Ice Cream

This frozen treat will make your insides feel like the temperature is taking a plunge, but your heart will be warm at the thought of a taste of Buttermilk-Plum Ice Cream. Its ruby-colored swirls—the source of its name— come from fresh plums. Half-and-half, buttermilk, and heavy cream help form its rich base, while peeled and chopped black plums add in beautiful color and flavor.
