Prepare batter by beating together the egg, milk and melted butter. Sift the dry ingredients and blend with liquid ingredients. Beat until smooth and no lumps remain (flour may be added to make a stiff, but not dry, batter). Heat vegetable oil to a depth of 1/2 inch in a large, heavy skillet. Stir well-dried fruit slices into batter; drain, drop by full tablespoons into oil. Fry until brown on both sides. Lift fritters out with a slotted spoon and dry on absorbent paper. Serve hot with a sprinkling of confectioners sugar.
