If you want to use a fresh pineapple, lay the pineapple across in front of you on the cutting board.  Using a medium knife, cut away the green flower base of the fruit. Repeat the same at the bottom of the pineapple and cut off the bottom. The fruit now has two straight cut surfaces at the top and bottom. This preparation makes it easy to place upright on the cutting board without tipping over.  The skin of the pineapple is slightly curved outward. To cut it off, you should angle the knife at the top. Cut the peel downward following the curvature. Cut down the next peel strip with the knife at an angle.  Rotate the fruit, again cutting down the peel until the pineapple is peeled entirely. Remove the brownish rigid parts you cannot eat with a small kitchen knife.
