When choosing a mango, pick one that is plump and heavy for its size. Most importantly, the mango should be fragrant when held near your nose. If you'll be using the mango right away, you will want to find a ripe one. Mangos are ripe when you can indent them slightly with your thumb. (Avoid mangos that are so ripe, they feel mushy, or mangos that have brown marks.)
Unripe (but not green) mangos will ripen in a few days when left on your counter. Refrigerate a ripe mango to make it last longer.
