Friends who buy vegetables every day often encounter such problems: what kind of vegetables do you want to buy today? Although the current planting technology and preservation technology are very good, and there are many fresh ingredients for us to buy all year round, it will also make it difficult to buy vegetables every day, and I don't know what to buy. Every time I encounter this problem, I choose to buy tofu because it is nutritious, delicate and suitable for all ages, and the price of tofu is affordable, and there are many ways to cook it, whether it is frying, frying and stewing. However, I don't know if you have noticed when buying tofu, some people will name the side tofu, but some people want the middle tofu, so when buying tofu, is it better to have side tofu or middle tofu? I'm going to talk to you about this issue today, and then I can buy it if I understand it, so I don't have to worry about buying the wrong one.

One: Side tofu.

The production process of tofu is relatively complex, it needs to go through a series of processes such as soaking, grinding, filtration, coagulation, and shaping. Side tofu is also the tofu on the side after the tofu brain is poured into the mold to set, because the tofu will be squeezed by the mold when it is set, so that the water inside can be better squeezed out, so the pressure on the side tofu will be greater, which also leads to the side tofu will be more compact, and the water and okara when squeezing will flow to the side, which will make the side tofu more okara, and the taste of the side tofu will be relatively rough and the texture will be harder. However, it is precisely because of these characteristics of side tofu that it is more suitable for stir-frying or stewing. When stir-frying, it is not easy to break, but when stewed, it can fully absorb the flavor of the soup, and the texture is more solid.

Two: Tofu in the middle.

The middle tofu is the position of a plate of tofu close to the middle, and the tofu in this place is relatively less stressed when it is shaped and squeezed, which also makes it retain more moisture. The more water there is, the smoother it becomes, and the more delicate and soft the taste becomes. However, because the middle tofu contains a lot of water, it will also be more weighed, usually if we buy the middle tofu at home and do not cook it in time, we can see a lot of water flowing out after a while, and the tofu will become significantly smaller. Usually, if you make cold tofu, tofu for soup, boiled tofu and other dishes, the middle tofu will be more suitable, it has a tender taste, and it melts in the mouth.

About the side tofu and the middle tofu, I believe we all have a certain understanding, they are not good or bad, but the taste is different, when buying, we only need to buy according to their own needs. However, no matter what kind of tofu we buy, the most important thing is to buy fresh, so let's talk about some tips when buying tofu.

1. Smell the smell.

Tofu is rich in protein and water, which also makes it particularly easy to breed bacteria, when the tofu is stored for a long time, or stored in a high temperature environment, bacteria will multiply quickly, decompose protein, and will also cause tofu to deteriorate and produce a sour taste. Therefore, when buying tofu, we should first smell the smell of tofu, if it is bean-flavored, it means that the tofu is still fresh; But if it smells sour, then the tofu has gone bad, so we don't want to buy it.

2, touch the feel.

When buying tofu, we can also gently touch the surface of the tofu with our hands. Fresh tofu is very tender to the touch, but if the tofu feels sticky to the touch, it means that the tofu is no longer fresh, and it is likely that the merchant did not sell out the remaining overnight tofu the day before.

3, look at the color.

Tofu is made from soybeans as the main raw material, and we all know that soybeans are pale yellow in color, so the color of tofu made from soybeans should also be pale yellow, not very white. If when buying tofu, we find that the merchant's tofu looks very white and good-looking, then we have to pay attention, this is likely to be the merchant in order to make the tofu look good, and add some whitening agents, this kind of tofu just looks good, and eating it may be bad for the body。
