Brulee'd Sweet Potatoes with Chipotle, Lime, and Cinnamon

• 8-9 large sweet potatoes, about 5 pounds
• 3/4 cup half and half
• 1/2 stick (1/4 cup) butter, softened
• 1 TBLS canned chipotle chiles, mashed or pureed
• juice of 1/2 lime
• 1 tsp. ground cinnamon

Roast the sweet potatoes until they are very soft. Cool, peel, and put in the bowl of an elextric mixer. Add all the other ingredients except the brown sugar, and mash. Spread into a shallow casserole, and sprinkle the brown sugar over the top. Heat at 350° until warm in the middle (OK if the sugar melts), then broil for a few minutes until the brown sugar is bubbley and crisp.
