Pineapple: Slice off the top and the bottom. Set one end on a flat cutting surface and cut along the sides, from top to bottom, removing all of the outer peel. Cut into quarters, cut away core, and chop into ½-inch dice. Place in a plastic bag, and freeze until firm. Prep time for one 4-pound pineapple: 12 to 15 minutes. Yield: 3 to 4 cups diced fruit.
