This is one of our most fun gadgets, and a huge time saver. Simply slice off the top of a pineapple, place the pineapple upright on your cutting board, and place the cylinder of the slicer on top of the core. Then just ratchet your way down to the base, and pull up a cored spiral of fruit! If you're careful enough to not slice down too far, you could also use the pineapple hull as a tropical cocktail cup. Just saying.
