There are three indications to determine the ripeness of a Mexican mango. First is the sniff test, in which ripeness can be determine if a sniff near the stem end draws a fruity, fragrant smell. Mangos with little or no scent generally need more time to ripen. Second is the squeeze test. Mangos often grow softer as they ripen, and the skin on an Ataulfo mango begins to shrivel when it approaches maximum sweetness. Third, the color test. Red mangos typically develop a warm yellow background as they ripen, whereas green and yellow varieties tend to retain the same color even when ripe.
To enjoy a ripe mango, cutting the fruit in the crosshatch method is best and "as easy as a mango pie." On a board, holding the mango with one of the narrower sides facing up, slice along each side of the pit starting 1/4 inch from the stem. Cut the flesh criss- cross, taking care not to cut through the skin. Press skin so fruit pops outward then remove the mango cubes. Then peel the center section, cutting off remaining fruit. Voila, a healthy and satisfying snack! SOURCE Mexican Mangos
