http://southernfood.about.com/od/mangorecipes/a/mango_recipes_2.htmCut fresh mangoes lengthwise, along the pit. Once you learn to locate the mango pit, the rest is easy. The long, 1/2- to 3/4-inch-thick pit runs the length of the fruit between the two plump cheeks.
# Cup the mango in your palm, then peel the skin from the flesh with a small, sharp knife.
# After determining the location of the pit and allowing for its 1/2- to 3/4-inch thickness, cut through the mango lengthwise down the side of pit until its fleshy cheek is cut off. Do the same for the other side.
# Cut the remaining fruit from the pit in thin slices; use in recipes that call for diced fruit, in sauces, or serve raw as an appetizer.
How to cube a fresh mango
# Without peeling, cut the fruit from the cheeks, as described above, score flesh into squares about 1/2- to 3/4-inch in size, cutting to, but not through, skin.
# Gently push the mango cheek inside out, pushing fruit cubes up and apart.
# Cut chunks from the skin to serve.
(The skin can cause irritation, so it should not be eaten.)
