The ideal of the poor is to eat meat every day. The rich eat meat every meal because they are rich. At some point they will make some special changes. They change to eat vegetarian food, or even vegetarian food. The best ingredient for vegetarian food is actually tofu. Tofu can be made of black tofu, mung tofu, and white tofu. As for frozen tofu, it is only found in the recipes of northerners. It will probably take some time to become popular in Dali, "Spring City" for "Spring City".

Tofu has a long history. It is said that it was invented by Liu An, the grandson of Liu Bang, the grandson of Liu Bang, the Emperor Gaozu of the Han Dynasty in China. When Liu An was cooking medicine and elixir on Bagong Mountain at the junction of Shou County and Huainan in Anhui Province, he accidentally invented tofu with gypsum. The tofu invented in the Han Dynasty did not heat up soy milk, but was primitive tofu. Its solidification and taste were not as good as the current tofu, so it failed to enter the mainstream of cooking.

Wu Yonglin secretly told Song Ningxue about this secret when he was in Xicheng, which made the ingredients of tofu suddenly become popular in Wei Chao. When he could see this kind of food that was just ordinary in his later generations again in a foreign land, Wu Yonglin couldn't help but sigh a lot. Tofu is still here, where can the beauty take her?

After Wu Yonglin put the green tofu into his mouth for the first time, he felt like he wanted to curse people. This was not tofu, it was simply a pot of kungfu. He chewed it in his mouth for a while and it was simply unreasonable.

Wu Yonglin was sure that such tofu was definitely not solidified with gypsum. Compared with the salt that has become very cheap from Tubo, tofu made with brine as a solidification agent is probably the first choice for these people. The tofu produced in this way has a relatively low moisture content, which is generally harder than the tofu pointed out from gypsum.

When everyone was eating and drinking, Wu Yonglin realized that he was really picky. Because he had eaten better ingredients, he was unwilling to do whatever he wanted. He had already lived a difficult life in this world and could no longer satisfy his desire for words when he was rarely relaxed. He felt that life in the future would be of relatively meaningless.

When the fine salt was extracted in Chacheng, Wu Yonglin retained the "edible calcium sulfate" obtained during the sedimentation process, commonly known as "edible gypsum", and did not need too much gypsum powder to order tofu. Looking at the small piece of gypsum that was still preserved in the bag, Wu Yonglin smiled brilliantly.

Black beans grow in the north, and mung bean yield is not high. Soybeans are still grown on a large scale. When Wu Yonglin was sweating profusely, he put a bag of soybeans in front of Zhao Huaien, Zhao Huaien wanted to stab him to death with a knife. He roasted this thing on the fire and sprinkled a handful of beans. After the "cracking" the beans cracked from the middle of his stomach were delicious. He didn't seem to eat enough in the chef. Now he was told that after soaking these excellent soybeans, he would use his stone mill to grind the beans into soybean cumin.

Zhao Huai'en was grinding croton flour when the donkey was milled. In order to take good care of the good horses in the stable, they took good care of them very carefully. Once things were exposed one day, they had to start running for life. Without a few strong good horses, their chances of survival were almost slim. Zhao Huai'en took it for granted that this monk used these beans to feed the horses that he now jealous. His only idea now was that it would be great if he could be a horse in the stable, so that he would never have enough beans to eat.

Zhao Huaien found an excuse for the monk, the prodigal son, and left angrily. He could not bear the torture when he watched his beloved beans endure the pain of being crushed to pieces.

Living in the late Spring and Autumn Period, the famous Lu Ban, was the famous Lu Ban. In the era when Lu Ban lived, people wanted to eat rice flour and wheat flour. They put rice flour in stone mortars and pounded with coarse stone sticks. This method was very laborious. The flour produced was coarse and fine, and it was pounded very little at a time. Lu Ban wanted to find a way to use less force and achieve greater effect, so he used two flat cylindrical stones of a certain thickness to make a grinding fan. A short vertical shaft was installed in the middle of the lower fan, made of iron, and a corresponding empty sleeve in the middle of the upper fan. After the two fans were combined, the lower fan was fixed, and the upper fan could rotate about the axis. On the opposite side of the two fans, there was a hollow chamber called a grinding chamber, and the outer periphery of the chamber was made of grinding teeth. The upper fan had grinding eyes. When grinding the surface, the grain flowed into the grinding chamber through the grinding eyes, and evenly distributed around it, and was ground into powder, flowed from the gap to the grinding disc, and passed through the sieve to remove the bran, so as to obtain flour.

Grinding is made of human, animal and hydraulic. Grinding with hydraulic power as power was invented around the Jin Dynasty. The power part of the water mill is a horizontal water wheel. The upper fan of the mill is installed on the vertical shaft of the wheel. The running water impulse water wheel drives the mill to rotate. This mill is suitable for installation in places where the water impulse is relatively large. If the water impulse power is relatively small, but the water volume is relatively large, another form of water mill can be installed: the power comes from a vertical wheel, and a gear is installed on the wheel shaft, which is connected to a gear in the lower part of the grinding shaft. The rotation of the water wheel is caused to rotate the mill through the gear.

Wu Yonglin looked at the beans soaked in the bucket, and then looked at the donkey that had already escaped by the stone mill. He couldn't help but sigh a few times. Living in such an era is not only his own sorrow, but also the sorrow of the people around him. Any novel invention will always be unfamiliar with the stone mill. The reason why Song Ningxue fell in love with him may be related to his frequent grinding of beans. It is impossible for both of them to not speak when grinding beans. If you keep doing the same thing and working easily, if you don't have anything to adjust, you will find that you will be very tired.

Wu Yonglin is good at telling stories. A seemingly boring stone milling skill often ends with laughter. (The author used to be a child, but actually didn't like to scoop the soaked beans into the milling eyes. If you see too much, you will easily feel dizzy, so you will often make yourself dizzy.)

The millstone seems to be quite heavy. After pouring some clean water into the grinding eye, under the lubrication of water, the stone mill can be run as if it is not enough. The ultimate goal of doing this is actually to remove the remaining croton powder in the stone mill. That thing is likely to cause stomachache after eating it, because Wu Yonglin is very particular about eating, and the time he cleans the stone mill is actually longer than the time he grinds the beans.
