Let’s be honest. The biggest problem with storing cut onions is not the onion itself—it’s the smell that invades everything in your fridge. Your butter tastes like onion. Your strawberries taste like onion. Your ice cubes taste like regret.
The jar trick completely solves this. Glass is non-porous, so odors bounce off like they’re hitting a force field. But if you’re using a baggie, put that baggie inside a second baggie. Double-bagging isn’t just for awkward grocery store moments—it’s for onion security.
Also, sprinkle a pinch of salt or a teaspoon of baking soda into the bag. It absorbs moisture and keeps the onion from getting weepy. Yes, I’m serious. Onions have feelings too.
