So, how do you store onions after cutting? Well, the first thing to know is that onions love to be cool and dry. Think of them like a cat - they like to lounge around in a cool, quiet spot, without any fuss or bother. If you can provide them with that, they'll be happy as clams.
One way to store onions is in an airtight container - think Tupperware or a glass jar with a lid. This will keep them fresh for a few days, and it's like giving them their own little onion condo. Just make sure to press out as much air as possible before sealing the container, or your onions might start to sprout.
Another option is to store onions in the fridge - this will keep them fresh for longer, and it's like putting them in a time capsule. Just wrap them tightly in plastic wrap or aluminum foil, and they'll be good to go. You can also store them in the freezer, but this will affect their texture - it's like turning them into onion ice cubes.
