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.
