Use a sharp knife to slice off the bottom, and then slice off the crown at the top of the fruit just below the leaves. Next, slice the skin away from the pineapple in vertical cuts, removing just the peel and eyes but leaving as much of the yellow fruit as possible. Finally, slice the pineapple away from the core: cut down through the fruit to remove it in planks. Discard the core. Then slice up your fresh pineapple.
