Step 1: A mango will have a pointy end and a flat end. Put the mango's flat end down on your cutting board. Step 2: Slice mango along all four sides moving your knife slightly away if you hit the pit. You'll have two large pieces and two smaller pieces. Step 3: Cut the fleshy halves of the mango diagonally along the flesh. Don't cut all the way through to the skin. Then cut the other direction to create a cross pattern that creates cubes. Step 4: Pop the mango flesh so that the squares pop out. Trim the squares off the skin. Continue the same steps for the other pieces of the mango.
