Making tofu is not a difficult task, of course, that was in later generations.

For the current Qingque tribe, it is not easy to make tofu.

Even with Han Cheng, who came from the future and had participated in the entire process of tofu-making for several times, it would still take a lot of effort to make tofu at this time.

It wasn't that his half-baked skills had declined or become rusty, but that he lacked the tools to make tofu.

Even a skilled cook cannot cook without rice, let alone Han Cheng who is only half-baked.

In addition to soybeans, grinding tofu also requires a stone mill, a hanging bag, brine or gypsum, as well as tofu molds and pots and pans.

There was linen in the tribe, and the linen was finely made and woven by Sister Bai Xue herself. There was no shortage of material for making slings, but there was also a shortage of cloth to be placed inside the mold to hold the tofu pudding.

With the several pieces of granite brought back by the caravan led by Shang and Mao, as well as the stonemason Mu Mu with an iron hammer and iron chisel, the stone mill can be made slowly.

The only thing that is a bit difficult is the brine or gypsum used to make tofu.

Without these two things, the ground beans can only be soy milk. No matter how hot it is burned or how much soy milk is ground out, it will not cause a qualitative change.

Han Cheng did not find any trace of gypsum among the many stones brought back by the trading team. That means he can only focus on brine now.

Brine has another name, called brine. Just from the name, you can see its origin with salt.

Brine is a by-product of salt and can be obtained from the process of boiling salt.

This is all Han Cheng knows about the origin of brine.

There is still a big gap between knowing this and making the brine.

At least the Qingque tribe has been cooking salt for several years, but they still haven't made brine.

Although most of it is because no one tries to get it, brine is difficult to get, so you can still get some from here.

After telling these things to Wu, the eldest senior brother and others, they were all a little discouraged. How could taking advantage of someone be so troublesome?

But then they became happy again because there were now professional stonemasons and carpenters in the tribe.

Many people are good at weaving and needlework.

Although he had never seen the brine that the Son of God mentioned, he knew where it came from. With his wisdom, he would be able to get it sooner or later.

This food called tofu is so troublesome to make, and I'm afraid it tastes even better than what the Son of God said...

The loss of several people only lasted for a short time, and they were immediately revived with full blood, and they were more motivated and expectant than before.

Han Cheng couldn't help sniffing when watching this scene. They were indeed a group of real foodies.

Although there are many tools needed to make tofu, you still have to follow them one by one.

After a few people happily decided on the plan to take advantage of Mu Tou, the first person Han Cheng found was the stonemason Mu Tou from the Qingque tribe.

Chiseling hard stone into regular and usable millstones is an extremely time-consuming and labor-intensive task.

Even with a hammer and a chisel in hand, it would not be easy to chisel it out, not to mention that wood had never been chiseled before.

Han Cheng found a branch and drew a few circles on the ground, then explained to Mu Shu what a millstone was and its general structure.

Compared to the carpenter Lame, the stonemason Mu Tou's comprehension ability was much worse. Han Cheng talked to him for a long time about a not-too-complicated stone mill.

The lame carpenter on the side took a while to understand what was going on before Mu Tou finally understood what was going on.

That is to chisel the two stones brought back by the caravan into two identical circles.

Then carve grooves on each of the two circular grinds.

These grooves are used to increase friction so that the beans and other grains that leak in can be better rubbed.

At the same time, it can also allow the ground materials to flow out better and faster along these grooves.

A hole should be drilled in the middle of the two grinding wheels to make them better connected together.

The difference is that the hole in the middle of the lower mill is a square, while the hole in the upper mill is a smooth round one.

When the time comes, use hard wood to make a wooden wedge of suitable size with a round bottom and upper part, and nail it firmly to the lower mill. Then push the upper mill upwards, and the upper mill will be able to rotate continuously.

Of course, the two holes in the middle for installing the wooden wedges do not need to be drilled through.

On the one hand, it is completely unnecessary, because it is sufficient without breaking through the millstone.

On the other hand, not only is it troublesome to break through, but the wooden wedges will also be exposed to the outside, which will easily accelerate weathering and wear.

After finishing these, you still need to grind the upper door and drill two holes.

A place between the center and the edge of a circle, closer to the center.

This hole needs to be drilled through the millstone, because when the time comes, the soybeans and other things that need to be ground will be poured into it through this hole.

The other one was opened on the side of the millstone, and was basically facing the hole for pouring beans across the center of the circle.

It is best to make this hole in a long or square shape, because the wood hammered in will not easily loosen.

In time, an 'L' shaped piece of wood will be hammered into this hole, but all you need to do is hold the upper part of the wooden handle with your hand and turn it hard, and the millstone on top will rotate, and it can be used to grind things.

Of course, this is just a small mill. If it is a heavy stone mill, you can only wedge a "I"-shaped tree stick more than half a meter long into it.

This is because the millstone is too heavy, and a person cannot turn it by standing still or using just one arm.

It needs to be pushed by hand, and the person follows the mill in circles.

It is rather troublesome to express it in words, but actually it is not really something that is too troublesome.

The only part that has relatively high requirements is the stone groove on the two sides of the millstone.

Their depth, coarseness, and density have a greater impact on the objects being ground, but the rest do not need to be too precise.

Mu Tou made a bitter face and said, “Isn’t this complicated enough?”

However, even though he thought this way, he did not back down. After understanding the great significance of this thing, he immediately patted his chest and promised that he would definitely make it.

What Han Cheng likes most is the enthusiasm of the people in the tribe, which makes people feel at ease.

However, sometimes doing things cannot be done just by passion, some things cannot be changed by human will.

Just like the wood nowadays, the louder you pat your chest, the harder you will slap someone in the face.

He had just made a promise and started working without stopping, but he encountered a problem that troubled him but he had no way to solve it.
