Here is the method that I use when cutting a whole pineapple. 1. Cut off the bottom and top of the pineapple. 2. Place the flat end of the pineapple on the cutting board and begin to trim the outer skin off.  You want to cut deep enough into the pineapple to remove “most” of the skin without losing or wasting too much of the pineapple. 3. Once all the skin is off, go back around and trim any remaining eyes or brown skin. 4. Next, cut the pineapple in half from top to bottom. 5. Then cut each half lengthwise. 6. Place each pineapple quarter flat on the surface of the cutting board and cut the core out of the pineapple. 7. Cut the pineapple into the size slices you want.
