Serves 6 to 8
4 pounds medium sweet potatoes
1 cup heavy cream
4 tablespoons unsalted butter
½ vanilla bean, slit lengthwise, seeds scraped
(add ½ teaspoon salt while mixing)
Kosher salt and freshly ground pepper
1. Preheat the oven to 400°.
2. Poke the sweet potatoes several times with a fork and bake for about 35 minutes, or until tender. Let cool to the touch.
3. Peel and transfer to a food processor. Puree until fairly smooth.
4. In a small saucepan, combine the cream with the butter and the vanilla bean and seeds. Bring to a simmer. Remove the vanilla bean. With the processor on, carefully pour the vanilla cream into the sweet potatoes and process until smooth. Season the sweet potato puree with salt and pepper, transfer to a bowl and serve.
