How to buy green onions:

1. Buy straight onions instead of straight ones

When you choose green onions, you will find a phenomenon that we often hesitate when choosing green onions, whether to buy curved ones or straight ones. It seems that there is not much difference, but in fact, the difference is quite big.

Generally speaking, the green onions planted in the north are straighter, while those produced in the south are more curved. The straight green onions taste heavier, while the curved green onions are lighter, so those who like to eat green onions can choose straight ones.

2. Buy tight and don't buy loose

When selecting green onions, we can pinch the onion body by hand. If the onion body of green onions is very tight and elastic, it means that green onions are fresh and full of water, which can be stored for a long time and can be purchased with confidence. On the other hand, the onion body is very loose when pinched, and it is concave when pinched, which means that the onion has been put for a long time and is not fresh. It is not recommended to buy it and it is easy to rot.

3. There are differences in thickness

When selecting green onions, the thickness of green onions is also an important criterion to judge the quality of green onions. The difference in the thickness of green onions does not mean that the quality of thick green onions is good, while the quality of small green onions is poor.

The difference between the thickness of green onions is more reflected in the taste. Usually, thick green onions are full of spicy taste, while small green onions are not so spicy, on the contrary, they are a little sweet. You can choose the thickness of green onions according to your own taste.
