Ingredients

Serves 8

　　5 1/2 pounds sweet potatoes (about 8 large), scrubbed

　　1 1/2 to 2 canned chipotle chilies in adobo sauce*, minced and mashed to a paste (about 1 tablespoon)

　　3 tablespoons unsalted butter, cut into pieces and softened

　　available at some supermarkets and specialty foods shops

　　

Step 1

Preheat oven to 450°F. and line a baking sheet with foil.

　　

Step 2

Prick potatoes and bake in middle of oven 1 to 1 1/2 hours, or until very soft. Cool potatoes until they can be handled and scoop flesh into a bowl. With an electric mixer beat potatoes with chili paste, butter, and salt and pepper to taste just until smooth and spread in a buttered 2-quart shallow baking dish. Potatoes may be prepared up to this point 1 day ahead and chilled, covered. Bring potatoes to room temperature before proceeding.

　　

Step 3

Reduce oven temperature to 350°F. Bake potatoes in middle of oven until hot, 20 to 25 minutes.
