How to cook onions? As we all know, if you buy too many onions, they will rot in the kitchen? Remove the rotten parts and raise them with clear water. Don't worry, potted onions won't make you cry, but they can help prevent colds.

Onion pot method:

Container: A shallow container can expose most of the onion, a daffodil bowl is the most suitable, or a glass that can be stuck in the lower part of the onion.

Cultivation: cut off the fibrous roots at the top of the onion and put them in a container. Add a little water and only touch the bottom of the onion.

Cheat: As long as the onion is not soaked in water, it will soon grow snow-white fibrous roots. Putting two aspirin in water will help it germinate quickly. If you keep it in a glass, you can also appreciate the beautiful shape of the drooping fibrous roots.
