Mangos are easy to handle if you know how. The mango has a large flat seed in the center, so you need to cut around it. Hold the mango upright on a cutting board and start cutting down the center of the wide side. When you hit the seed just work right along it. Then turn and repeat. This is what you will have.
Now score the fruit with a paring knife and scoop out diced mango with a spoon
There you go! Your mango is ready to use!
