Ingredients

• 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

Instructions

1. Preheat oven to 450°F. and line a baking sheet with foil.
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.
3. Reduce oven temperature to 350°F. Bake potatoes in middle of oven until hot, 20 to 25 minutes.
