1.Degree of dryness
When buying, we can touch the top of the onion with our hands, and the good onions are dry to the touch. And if the top of the onion doesn't feel dry enough, such an onion is easy to mold, so such an onion is not recommended for everyone to buy.
2.Look at the shape
The perfect onion ball is complete and beautiful, which indicates that the onion is growing well. And if you encounter a misshapen onion, it may be underdeveloped. It is also necessary to see if the onion is damaged or squeezed out of shape, if it is damaged, it is not suitable for preservation, so it is not recommended to buy it.
3.Look at the top point
Onions are actually a particularly easy vegetable to sprout, and if they are stored in a relatively high temperature place and not stored properly, the tip of the top will start to sprout after being wet.
Although the onion does not produce harmful substances to the human body after germination, it can still be eaten, but because it sprouts, the sprout will absorb the original nutrients in its body, so that its water and nutrients are lost.
4.Pinch it
The onion itself is made up of layers of skin, so it will be more saturated and have more moisture. When buying onions, we can pinch them with our hands, and if it is an onion with a hard feel, it means that it is a good quality onion.
If the onion feels soft, it means that the internal flesh of the onion has begun to deteriorate and rot. So when we buy onions, we have to choose those onions that feel hard.
If the onion is boiled for too long, the onion batter will not only become more and more soft, but the nutrients in the onion will also flow out a lot, reducing the effect of boiling onions.
The simple way to cook onions is to peel off the onion skin and cut it into shreds. Put it in a pot of water, heat until all the onions are boiling, simmer and serve in 15 minutes.
