6-8 med. size sweet potatoes, uncooked
1 stick butter
1 c. granulated sugar
1 c. brown sugar, packed
1 tsp. cinnamon
Water

Peel potatoes and slice into a buttered casserole dish. Add butter, sugar, cinnamon and a small amount of water. Cover and bake in a 350 degree oven for 1 hour or longer (the longer the better). Check on water occasionally as potatoes bake and add more if needed.
