How to Keep Onion Fresh After Cutting

How to Keep Onion Fresh After Cuttingに挑戦したい方へ、最短で成果を出す 手順書をご紹介します。

The number one enemy of a leftover onion is air. Air dries it out and lets those strong sulfur compounds escape and stink up your yogurt. You want to lock that smell in and lock the air out.

Grab a piece of plastic wrap. Seriously, just a square of it. Press it tightly against the cut side of the onion.

Imagine you’re giving the onion a little hug. You want the wrap to cling to the surface, with no air bubbles. Then, toss the wrapped half into a resealable bag or a container with a lid.

I do this every time, and my onions stay crisp for a good five to seven days. It feels like a tiny victory every single time I open the fridge.

What About The Smell?

Ah, the classic onion-scented fridge. Even with wrapping, some of that aroma escapes. A little hack? Store your wrapped onion in a glass jar with a tight lid. Mason jars work like magic.

Glass doesn’t absorb smells like plastic does. It’s like a little time capsule for your onion half. Plus, it looks cute and organized.

Another trick I love is to rub a little neutral oil (like canola or avocado) on the cut surface before wrapping it. The oil creates a barrier, keeping moisture in and oxygen out. It’s like sunscreen for your onion.
