Best Way to Rippen Bananas Quickly

I bought bananas at a local store and sometime they just dont rippen. I bought them green. I put in paper bags etc.no luck. I have some on counter for 5 days so far still green and hard what should I do? thanks

I usually put bananas in a brown paper bag which helps it ripen quicker. However, I have also heard that you can put them in a sealed plastic bag - along with an apple slice - which works well too.

I have heard about putting a whole apple in a paper bag, it works also. Just a suggestion

Store in a brown paper bag with ripe fruit of any kind, don't store in the fridge just turns the skins black with out ripening the banana.
