Place the pineapple on a cutting board and cut off the top and bottom parts with a knife. About ¼-½ inch (0.64-1.27 cm).

Place the pineapple on its bottom and start cutting off the skin starting from top to bottom. Continue this process using the eyes of the pineapple as your guideline, trying not to cut off too much or otherwise you will take off a good portion of fruit with it. Remove any remaining eyes with the tip of your knife or with a potato peeler.

At this point you can cut the pineapple into slices removing the core with a knife or a small cookie cutter. Otherwise, cut it lengthwise into four pieces.

Place each piece on its end and remove the core by cutting it from top to bottom.

Cut each piece lengthwise and then across to dice it into the desired size.
