Here, a speedy trick to help it ripen an almost rock hard avocado faster (aka almost overnight).
What you need: An apple, a brown paper bag, and that not-quite-ready avocado
What you do: Place the apple and the avocado together in the bag, then fold over the opening as best you can to seal it off. Let the fruits sit together overnight and--voilà! You’ll have a ripe avocado, ready to be enjoyed.
Why this works: Apples give off ethylene, a naturally occurring gas required for the ripening process.
So does this work with other fruits and veggies? Yes! Bananas, corn, tomatoes… sometimes nature just needs a little help.
