" Follow the directions for Lightest Fluffiest Doughnuts, but replace the sour cream with 8 ounces mashed sweet potato. Add allspice, mace, and cinnamon to the batter. Prepare the doughnut batter and fry as instructed above. Combine 1 cup maple syrup and 1 teaspoon lemon juice in a small saucepan over medium-low heat. Cook until reduced to 3/4 cup -- 15 to 20 minutes. Coat hot doughnuts and holes with glaze and sprinkle with 1 cup toasted, chopped walnuts. Let glaze set and serve immediately. Will keep in an airtight container for up to 2 days."^^<http://www.w3.org/2001/XMLSchema#string>
