Serves 8 / Ingredient tip: Look for orange-fleshed sweet potatoes with dark skins, often labeled as garnet yams. They are sweeter and have a higher moisture content than pale-fleshed sweet potatoes.
2 pounds orange-fleshed sweet potatoes, peeled and cut into 1-inch pieces
2 tablespoons unsalted butter
1/2 teaspoon ground cinnamon
1/4 teaspoon ground allspice
1/2 teaspoon freshly grated (not dehydrated) orange zest
3 tablespoons reduced fat (2 percent) milk, or more to taste
1. Put potato pieces in a pot and cover with cold water by 1 inch. Bring to a boil, then simmer until tender, 8–12 minutes. Drain, then pour back into pot (if using a hand mixer) or a mixing bowl (if using a standing mixture with paddle attachment).
2. Add butter, cinnamon, allspice, and orange zest. Beat on medium speed until smooth and creamy. Add milk and beat until uniform and creamy. For a lighter texture, add a bit more milk. Stir in salt to taste.
