The recipe yield is:
*Note:1 Enough to fill 9x12-inch baking dish. *Note:2 Enough to almost cover potatoes. Peel sweet potatoes and cut in 1/2-inch slices to loosely fill baking dish. Mix sugar, salt and cinnamon and spread over sweet potatoes. Almost cover potatoes with water. Add thin slices of butter to dot top of sweet potatoes. Cover with a good vented pie crust. You can moisten top of crust with milk and sprinkle with sugar if you desire. Bake in 350-degree oven until potatoes are tender and crust is golden brown. Serve with cream or (fat saving) sweet milk.
