Scrub yams and boil in skins until tender (about 30 minutes). Drain and peel or use canned yams. Cut in halves or 1/2 inch slices and arrange in greased baking dish.
For an exceptionally pretty dish, place thin slices of fresh orange with peel diagonally across top of potatoes before adding sauce.
Combine remaining ingredients; cook, stirring until thickened. Pour over yams; cover and bake 20 minutes in 350F oven. Uncover and bake 15 minutes longer. Garnish with parsley.
Serves eight to ten.
