Peel and cut the sweet potatoes into 1- to 1-1/2-inch chunks. In a large bowl combine the maple syrup, mustard, oil, salt, and pepper; add sweet potatoes and cranberries. Toss to coat. Transfer mixture to a 3-quart baking dish, spreading mixture evenly.
Bake, uncovered, in a 400 degree F oven for 30 to 35 minutes or until potatoes are glazed and tender, stirring twice. Makes 8 servings.
