Tired of bananas ripening too quickly and turning black? As a parent who buys in bulk for my fruit-loving kids, I've dealt with plenty of wasted bananas left untouched in the fruit bowl.
I've discovered a reliable, waste-reducing trick that's worked wonders in my kitchen: wrapping the stems with plastic wrap. Here's how it works, step by step.

1. Separate the bananas from the bunch.
2. Take a piece of plastic wrap (cling film).
3. Wrap the stems tightly to create an airtight seal.

That's it! Your bananas will stay fresh and yellow 3-5 days longer than usual, without those pesky black spots.
Easy, inexpensive, and far better than tossing them out. For up to a week of freshness, wrap the stems as tightly as possible—the snugger, the better!
Bananas release ethylene gas as they ripen, which speeds up browning. This gas escapes primarily through the stems, so sealing them with plastic wrap slows the process and keeps your bananas fresher longer.
