Mango is protected by its thick skin from any pesticides that are sprayed on the fruit, though rinse before cutting open.
When choosing mango, look for fruit that is bright in color and has a sweet, fruity smell; if it doesn’t have that smell, steer clear. Mangos should be slightly firm, but yield to the touch. Generally speaking, the softer the mango, the sweeter the fruit, but if it's too soft, it may be rotten inside. Store in the refrigerator crisper.
