When you buy bananas, break them apart into individual bananas instead of leaving them in the bunch.
Why YSK: The stem of the bunch is the main culprit for releasing ethylene gas, which is basically a ripening accelerator. By separating them, you significantly slow down this process. This means your bananas will stay yellow and edible for far longer, saving you from having to eat a dozen bananas in two days or, more likely, throwing them out. No more premature browning, unless you’re specifically aiming for banana bread. Your fruit bowl (and wallet) will thank you.
Put them in the fridge and they’ll last for weeks. They might turn brown after a few days but inside they’ll be fine. Put them in an airtight container and they’ll last even longer in the fridge.
