🍌 The “one kitchen item” trick for longer-lasting bananas
The item is plastic wrap (cling film). Wrapping the banana stems, rather than the whole fruit, may slow ripening by reducing the release and spread of ethylene gas. Food-storage guidance from the University of Nebraska also recommends wrapping banana stems with plastic wrap or foil.

How to do it
Keep the bananas in a bunch or separate them.
Wrap the stem/crown tightly with a small piece of plastic wrap.
Keep them somewhere cool and away from direct sunlight, the stove, and other heat sources.
Keep bananas away from other ethylene-producing fruit such as apples and avocados.

Once they’re fully ripe, you can refrigerate them. The peel may turn brown, but the flesh can remain good for several more days.

Does it really add 10 days?
Sometimes, but don’t treat 10 days as guaranteed. Results vary with the bananas’ starting ripeness and room temperature. Testing has found that stem wrapping can add several days, while other tests have found only a modest difference.

Best simple strategy: wrap the stems + keep bananas away from heat and other fruit + refrigerate once ripe.
