Directions In a large bowl, cream butter and sugar until light and fluffy. Beat in the egg, orange peel and vanilla. Combine the flour, baking powder, cream of tartar, baking soda and salt; add to creamed mixture alternately with sour cream. Fold in rhubarb and walnuts. Transfer to two 5-3/4-in. x 3-in. x 2-in. loaf pans coated with cooking spray. Bake at 350degrees for 40-45 minutes or until a toothpick inserted near the center comes out clean. Cool for 10 minutes before removing from pans to wire racks. Yield: 2 loaves (6 slices each). Editor's Note: If using frozen rhubarb, measure rhubarb while still frozen, then thaw completely. Drain in a colander, but do not press liquid out.
