Yam Bake for Thanksgiving

3 large sweet potatoes
1 1/2 c. mini marshmallows
1/2 c. packed brown sugar
1/4 c. melted margarine
1/2 c. orange juice
1/4 teaspoon ground cloves
1/4 teaspoon dry mustard

Cook potatoes.  I boil them.  Cut potatoes in half length wise.  Place half of cooked sliced potatoes in 1/2 quart casserole.  Layer half of the marshmallow (3/4 cup) over potatoes.  Then layer second half of potatoes over marshmallows.

Mix together remaining ingredients and pour over potatoes (except marshmallows).  Bake 350 for 20 minutes.  Remove and top with remaining marshmallows.  Return to oven and brown 10 minutes.
