To Ripen Avocados, Bag With Bananas.
You may know the trick of putting bananas in a paper bag (on top of the fridge) to ripen. But did you know it works for other fruit, too. In fact putting a banana in the SAME bag with fruit, like avocado, actually help the avocado ripen more quickly. It’s all because of a gas called ethylene, which is released as fruit ripen. It acts like a hormone, telling nearby fruit to ripen too (ever wonder how all the apples on the tree become ripe about the same time?). Different fruit release ethylene at different rates – bananas release a lot which is why they can help other fruit to ripen more quickly.
