Four small sweet potatoes bake until tender, then get scooped out and mashed with fat-free half-and-half, one finely chopped chipotle chile, and a teaspoon of adobo sauce. The spiced filling goes back into the shells for a second round in the oven until the tops brown and the edges caramelize slightly. Reduced-fat sour cream and chopped cilantro finish each potato at the table. Total time is 90 minutes, serving 4.
