Wash, pare, soak, and cut potatoes in one-fourth inch slices, shape with French vegetable cutters; or cut in one-half inch cubes. Cover three cups potato with White Stock, cook until soft, and drain. Cream one-third cup butter, add one tablespoon lemon juice, one-half teaspoon salt, and few grains of cayenne. Add to potatoes, cook three minutes, and add one-half tablespoon finely chopped parsley.
