Mutsu is a cross between Golden Delicious and Indo. It was developed in Japan in the 1930's and arrived in the United States in the late 1940's. The crisp, white flesh is juicy and has a touch of tartness, for an excellent dessert apple. In taste tests of Golden Delicious and apples descended from it, Mutsu scores on top. It does not make a particularly diverting pie. Sauce will have more flavor if you leave the peels on while cooking and then separate them with a strainer or colander. Mutsu is a worthwhile cider apple.
