Have you ever wanted to make a something that required ripe fruit but the fruit you just bought is rock hard? Well, to help fruit ripen faster, place the fruit in a brown paper bag and close it loosely. They should ripen in a couple days.
As fruit ripens it gives off a gas. When contained that gas will help ripen other fruit which explains the saying ‘one bad apple spoils the bunch.’ To accelerate the ripen process even faster, place a piece of ripe fruit in with the unripe fruit. I did this with peaches. I had a couple peaches that were overripe…like on the border of not being edible. I placed them in the paper bag with hard peaches that I just bought. The very next day the hard peaches became very ripe. I’m talking perfectly soft yet firm where I could bite into it with no problem. I was actually surprised this worked so well. You don’t have to use an overripe peach to help ripen other peaches. You could use a ripe banana, tomato or any other fruit.
I hope this helps.
