Mangos are the most popular fruit in the World. Don’t judge a mango by its color – red does not mean ripe. Squeeze gently to judge the ripeness. A ripe mango will “give” slightly and a firm mango will ripen at room temperature over a few days. To speed up ripening, place mangos in a paper bag at room temperature. Once ripe, mangos can be moved to the refrigerator to slow down ripening for several days.
