Use A Paper Bag Or A Newspaper
Place the mangoes in a paper bag or wrap it with a newspaper and leave it undisturbed for the night in order for it to release some ethylene, which is an odourless gas that speeds up the ripening process. Remove the mangoes from the bag once they start giving off a fruity smell and softened. Alternatively, you can also add bananas and apples to the bag as they also emit ethylene, which fastens the ripening process even more.
Use A Bowl Of Uncooked Rice
Submerge the mangoes in a bowl of uncooked rice for a night for it to emit ethylene, which as we now know helps in ripening the mangoes faster. Check the mangoes after every 6 to 8 hours, your mangoes will ripen in a day or two.
You Need Time And Patience
One of the oldest Indian household methods of ripening mangoes. You need to just leave your mango on the kitchen shelf at the room temperature for several days. This is no doubt the most time-consuming method, but gives the best results.
