"Childish, don't we have a normal seasoning at home? What is this flowery thing, this smell ......" Xu Hanliang glanced at the childish girl, and did not say the words later.

"Seasoning? What is Lang Jun referring to? Zhiniang has already laid the vinegar cloth, if Lang Jun is greedy, then wait a few days for Guan Zhiniang to receive the salary and cut a few hangs of meat and give Lang Jun a tooth sacrifice. ”

"In the past few days, Lang Jun has worked harder, after all, Lang Zhong also said that you are recovering from a serious illness, and you are most taboo and patient."

The childish lady snapped her fingers and obviously didn't react, she just thought that the soup cake with clear soup and little water did not meet her own Langjun's appetite, and she was greedy, she gritted her silver teeth and said.

Okay,

Xu Hanliang was silent, and he knew it in his heart.

Lao Xu owed a huge debt in order to buy official accommodation, and was put in prison simply and neatly, and Lao Xu's family had nothing else of value except for the old mansion where he lived.

Even now, the rations of the master and servant are all maintained by the childish lady alone.

Now this girl is looking for a cheap servant in the big family next door, because she is a slave, she naturally can't get anywhere in the monthly money, and a dozen copper plates per month are the only living expenses for the two masters and servants.

This amount of money to feed one person is repaid.

Now that Xu Hanliang has recovered from a serious illness, he has to pay for medicine, at least he glanced at the kitchen when he came back, I am afraid that the idea of soup cake in his hand can be regarded as the only food in the entire old Xu family.

Of course, there are also some beans and other high-protein products.

I took two bites without knowing the taste.

I thought I couldn't swallow it, but my stomach acceptance was still good, I barely drank a small half bowl, and some warmth finally rose in my arms and legs, and when I looked up again, I found that my little maid had begun to lick the edge of the bowl with her rice bowl.

"No, Lang Jun, I have just recovered from a serious illness and have a bad appetite, you can eat the remaining half of the bowl of soup cakes, and you are not allowed to waste it."

The tiger lowered his face, Xu Hanliang's soup bowl was stuffed into the hand of the child, and he walked out of the main courtyard alone.

As expected,

The kitchen was so clean that even the flies were in tears, and in the corner of the sauce jar was a black strip of cloth on a wooden stick that lay across the sauce jar.

The color is not mentioned for the time being, but when you smell it closely, it exudes a strange smell.

Vinegar cloth......

Xu Hanliang hid his face and looked at it.

The vinegar cloth developed by the Tang Dynasty army to facilitate marching and fighting is easy to store and carry, but if you really eat this thing, won't your stomach make a big fuss in the heavenly palace?

Shaking his head, Xu Hanliang was about to find an opportunity to throw this vinegar cloth into the garbage, but he accidentally found several crystals the size of little fingers in the small jar next to the stove.

The color is gray-green, and it is salt.

Xu Hanliang was stunned for a moment, of course he knew very well that even in the Song Dynasty, the source of salt was very precious.

Although there was already a purification process for edible salt in the early Tang Dynasty, it was at most a simple cooking and purification, not to mention any technical content.

Usually, this part of the craft has been in the hands of the superiors, and the salt eaten by the general public is mainly mineral salt and sea salt, although the Western Xia has green and white salt into the territory of the Great Song Dynasty, but it has been ordered to prohibit.

Selling smuggled salt is a felony.

But there is no doubt that selling salt is a huge profit, especially when officials and businessmen firmly control salt, although ordinary people do not order to prohibit the sale of salt in private, but once caught, they can be killed at every turn, and the punishment of the Great Song Dynasty is far less merciful than it seems.

Selling salt, Xu Hanliang is not ready to touch it.

But to put it bluntly, the way of money in this world can not escape from food, clothing, housing and transportation, and the people take food as the sky, and they can't go wrong by starting from food. He didn't want to cross over and become the first unlucky guy to starve to death because he couldn't adapt to the soil.

For the sake of your belly, it is imperative to earn money.

If you can make a small profit from this, and by the way, you can fish out Lao Xu, who is waiting for the autumn queen in the prison, it would be great.

What to do, though?

Xu Hanliang sat on the small bench, pinching his chin and thinking, suddenly, he caught a glimpse of the beans stacked in the corner of the wall with a flash of inspiration in his mind, and then rolled up his sleeves and turned upside down.

There were a lot of bottles and cans in the kitchen, Xu Hanliang washed the beans, and then began to get busy.

Monosodium glutamate is something that Xu Hanliang wants to ponder.

Glutamic acid is extracted by grain fermentation and purification, with beans rich in protein and sugar as raw materials, crystallization and precipitation through electric point, ion exchange to extract glutamic acid, and then decolorization, iron removal, evaporation, crystallization to obtain glutamate crystals.

Although it may seem difficult, the operation in it is not difficult.

If an ordinary high school student knows the tricks, there will be no difficulty, let alone Xu Hanliang, a high school teacher, even if some of the details cannot be perfected, Xu Hanliang can also be a seven, seven, eight, eight.

Monosodium glutamate, in layman's terms, is monosodium glutamate.

In this situation where food is a little poor and selling salt is a felony, Xu Hanliang had to make this decision, and even used distillation to make a small pinch of snowflake salt.

After tossing for a whole afternoon, Xu Hanliang let out a breath.

The monosodium glutamate made by the most primitive method is far less crystal clear than that seen in later generations, but the chemically purified monosodium glutamate is snow-white, but it is not far from ten.

"It doesn't look bad, it's a little worse in terms of taste, but it's quite successful."

After a long mouthful, Xu Hanliang nodded.

Turning his head to see the childish girl outside the house looking into the kitchen, Xu Hanliang sighed.

This girl has been here six times in an afternoon.

"Taste it."

Xu Hanliang beckoned to Zhi Niang, and then twisted a grain of monosodium glutamate and put it into Zhi Niang's mouth, the latter was still suspicious, his small mouth opened and sipped, but he didn't wait for her to say something.

One of the child's faces tensed, and her eyes widened.

She only felt a strong umami explode on her taste buds, and her whole person was stunned.

"Lang Jun, this thing is ......"

The childish lady grabbed Xu Hanliang's arm and hurriedly asked, Xu Hanliang didn't say much, he felt that it was difficult for him to explain to the little maid in front of him who had been poisoned by feudal ideology tea what protein and glutamate were.

"A little bit of a little thing, child, what do you think if you put this thing in the soup cake?"

Xu Hanliang asked.

Soup cake ......

The young girl was stunned, and then her eyes narrowed.

If you put these umami condiments in the delicious soup cake to taste, wouldn't it be much more delicious than putting vinegar cloth? Subconsciously, the little maid who didn't feel too hungry screamed in her stomach.

Xu Hanliang smiled, casually collected the purified snowflake salt and monosodium glutamate into two small jars, and then he walked to the courtyard, thinking about what to do next.

Even if he is not a businessman, Xu Hanliang also understands the truth that strange goods can be lived.

But at this moment,

Bang! Bang! Bang!

There was a knock at the door.

Then the courtyard door was pushed open, and one leg stepped into the small courtyard, and when he saw Xu Hanliang standing in the middle, he immediately walked in three steps and two steps.
