Check the color for the variety you have, since ripe mangoes are not always yellow or red
Gently squeeze the mango; it should yield slightly to pressure
Smell near the stem end; a ripe mango often has a sweet, fruity aroma
Look for a fuller shape and slight plumpness
Avoid mangoes that are very hard and have no scent
Avoid mangoes with large wrinkled areas, deep soft spots, or mold
Let firm mangoes ripen at room temperature
Refrigerate only after they are ripe
