Trim the pineapple. Use a sharp knife to cut off the top and bottom of the pineapple.
Halve the pineapple. Balance the pineapple on the cut end so it’s standing upright. Slice down the center from top to bottom.
Separate the core. Open the pineapple so you’re looking at the center. You should see a lighter section in the middle running from top to bottom. That’s the core. Use your knife to cut a V-shape, angling the blade inward towards the middle. Unless you have a very large knife, you’ll want to start with the tip somewhere near the middle of the pineapple, then turn and do the other side, lining up the cuts to separate the center core.
Remove the core. Make a final cut through the pineapple on both sides to create four quarters with no center core.
Slice each quarter into pieces. Working with one quarter at a time, slice the flesh down the middle from top to bottom without piercing the skin. Then cut crosswise to make small pieces, again leaving the skin intact. Some pieces may look like triangles, some may have a flat top. Both are delicious.
Remove the skin. Carefully run the knife along the skin, separating the fruit from its armor. That’s it! You can serve the quarters with the skin like a boat, perhaps with some toothpicks on the side. Or, use, refrigerate, or freeze the pineapple chunks as you wish.

Notes
Use a sharp knife to prevent slipping. As the saying goes: you’re more likely to cut yourself with a dull knife than a sharp one! If your knife is feeling a bit dull, use a serrated knife for anything involving the outer skin, like trimming the top and bottom.
