Talking about onions

Onion is a kind of food that we often eat in our daily life. There are many ways to eat it, such as raw, stir-fried, stewed and so on. And because of its peculiar taste, many people also like to use it as a side dish and ingredient. When it is mixed with some dishes, the taste will be different, especially versatile. Besides eating method and taste, onion has high nutritional value, and contains a lot of protein, minerals and various dietary fibers. Eating regularly is good for lowering blood pressure and refreshing.

In the market, there are three kinds of onions, namely purple onion, yellow onion and white onion. These three kinds of onions look just different in color, similar in shape and size. For these three kinds of onions, many people think that there is no difference, or they all know that there is a difference, but they don't know the specific difference, so they don't know what to buy when buying. Don't worry, let me tell you the difference between these three kinds of onions. Let's have a look.

First: taste.

In taste, the main difference is that the water content and spicy taste of these three onions are different. In terms of water content, white onion is undoubtedly the highest among the three, followed by yellow onion and purple onion (of course, this is only a comparison between the three, and the water content of purple onion is not low, but it is not as good as the other two). If it is spicy, the purple onion is higher and tastes sweet and spicy; White-skinned onions are sweet, have a particularly light spicy taste and are tender; Yellow-skinned onions are somewhere in between.

Second: nutrition.

Nutritionally speaking, purple onion has the highest nutritional value, because it contains an antioxidant-anthocyanin, which can protect the human body, remove free radicals that damage normal cells in the human body and prevent cell aging. In addition, purple onion also contains a lot of minerals needed by human body, and eating more can bring great benefits to human body. White-skinned and yellow-skinned onions contain the most carotene and vitamin C, which can help relieve fatigue if eaten regularly.

Third: practice, eating and using.

Because purple onion has the strongest spicy taste, it is more suitable for barbecue, side dishes and stir-fried yellow onion. It is sweet and moderately spicy, so it is best to eat it raw or cook it with seafood. White-skinned onions are the sweetest, not too spicy, and are generally best used to make vegetable salads and snacks (onion rings and the like).

Fourth: save.

Because the water content of three kinds of onions is different, their storage time is different. White onion is undoubtedly the one with the shortest storage time (provided that the storage method is the same). Yellow onion is the second, and purple onion is the longest preserved.

When cutting onions, the juice easily splashes on your eyes. As long as it is splashed, it will basically "burst into tears." For this, you can cut the onion into several large pieces, then soak it in clear water for about 20 to 30 minutes, and then pick it up and cut it, so it won't burn your eyes.
