Boil whole yams 20 to 40 minutes or until tender but not mushy. Drain and cool, then cut into 1/4 inch thick slices. Arrange slices, overlapping, in a buttered shallow casserole. Dot with butter, then sprinkle with brown sugar and raisins. Drizzle with rum. Bake uncovered at 350 or until bubbly and glazed. This recipe is adapted from Sunset "Easy Basics for Good Cooking". It is absolutely my favorite because it is not gooey sweet. Besides, I love raisins !
