To perfectly slice a mango, start by cutting down from the top on both sides of the large seed in the middle. Keep the skin on, and gently score vertical lines through the mango flesh, being careful not to cut through the skin. Then, make horizontal cuts to create a grid of squares. Once the mango is diced, use a large spoon to scoop the flesh out from the skin. I like to make them small pieces so I can easily scoop them up with a tortilla chip!
