With bananas
It may sound strange, but placing some bananas near peaches, or any fruit you'd like to ripen, can help them to soften faster.
Bananas, as they ripen, release ethylene gas. This gas breaks down the cell walls in any surrounding fruit. This leads to the breakdown of sugars in fruit, giving you soft, juicy peaches in half the time!
With a paper bag
Ripening a rock-hard peach can take a couple of days, even up to a week, but by using a brown paper bag you can decrease the wait time significantly. Granted, you'll still need to wait at least a day or two.
Simply place your peaches into a brown paper bag and roll the top shut. While peaches sit, they release gases that then ripen the fruit. Placing them in a paper bag allows those gases to concentrate and give you ripe, juicy fruit even faster.
