Ingredients
3 pounds whole sweet potatoes, pricked with a fork
salt and ground black pepper to taste
½ cup buttermilk
½ cup whole milk
6 tablespoons butter, softened
Directions
Preheat the oven to 425 degrees F (220 degrees C). Adjust an oven rack to the upper-middle position. Line a baking tray with aluminum foil.
Bake potatoes on the prepared tray in the preheated oven until tender, 45 to 60 minutes. Peel when cool enough to handle.
Purée peeled potatoes in a food processor until smooth; season with salt and pepper. With the motor running, add buttermilk and milk gradually through the feeder tube, then butter. Continue processing until silky smooth.
