Shao Qing's gaze was warm and warm, revealing the meaning of mentioning something.

He turned to Yao Huan and said, "Yao Niangzi, didn't you ask me that day, did the doctor use an iron pot to make medicine now?" This issue is also what I have come to discuss with Su Gong today. In the present world, a good iron pot is no longer rare, and herbs such as cassia seeds, etc., are naturally better after frying, not only when grasping the medicine formula, it is easy to mash, and when decoction is boiled, the medicinal power is also easier to come out. ”

Su Song sighed: "That's true, then what you said is like roasted tea, roasting beans, what is the method?" ”

Yao Huan hurriedly replied respectfully: "Oh, because the younger generation heard Mr. Shao say that the croton in the herb is also best fried to the end, so he had a whim, and fried the beans of the big eater in the iron pot of Guozixue, and then boiled the water to drink. He also talked to Mr. Shao, he said, there is a process in my dynasty tea-making, after steaming, squeezing, and grinding tea, it is called 'Guohuang', which is to take tea cakes and bake them on a charcoal fire after being soaked in boiling water and exposed to the scorching sun. Mr. Shao said that the difference is nothing more than that the tea leaves are first ground and pressed into cakes, and then yellowed, while the beans of Fanshang are more like fried herbs, which are first yellowed and then ground. ”

Yao Huan said this, paused, and thought that communicating with Su Song about this matter was like doing a roadshow, for a while, he didn't just care about himself like a sparrow, and he had to let Su Song digest the information.

Today, she suddenly knew that she was coming to Sufu, and she was eager to receive a reward, after all, when she was today's royal pen, it was more attractive than a group photo of celebrities in a hot pot restaurant.

But what taught her more about planning was to ask Su Song how to make a device for roasting coffee beans.

After all, this Su Song in front of him, like Shen Kuo, is not only an important minister who is in and out of the prime minister, but also the top two scientists in the Great Song Dynasty!

Su Song is especially proficient in all kinds of mechanisms, he can even build the water transport instrument elephant platform, which is regarded as a masterpiece of the astronomical clock by Chinese and foreign scientists in later generations, can't he give himself the idea of a bean roaster?

At the same time, Yao Huan still had a thought in his chest, and he also let it go.

Mr. Shao is such a good person. I just muttered a few words to him that day, it would be nice to improve the efficiency of manual bean roasting, and he thought about it.

Judging from the fact that he took the initiative to talk about it, he doesn't seem to have any problems with me, and he really hopes that I will succeed in starting a business.

Yes, yes, go back and ask him, do you want to develop his Arab circle of friends into my supplier? He is not yet developed, and it is estimated that he does not have much money to invest in my store, so why not ask him to use technology and contacts to buy shares?

Over there, Shao Qing saw Yao Huan looking at him with a shallow smile of thanks, and said secretly in his heart, Yao Niangzi, you don't have to thank me, I changed the topic, but I have my own abacus. For Su Gong, I actually have something to ask for, and it just so happens that what I ask for is also to everyone who knows how to be clever with bamboo and wood instruments...... Su Gong is such a person, or he can untie the mechanism of the god's arm crossbow.

"Shao Lang, Yao Niangzi, the two want to live in Jingzhao and Gyeongju when they were young, and they don't know much about making tea, just by the word 'roasting', they think that tea is on the charcoal fire, but in fact, it is not so simple."

Su Song turned his head and said to the scholar standing beside him, "You go and get the old man's 'baking basket' and stove." ”

The scholar said yes, and soon he came back with another servant, one of whom was carrying a small thing.

"The old man is a native of Tong'an, Quanzhou, Liangzhejiang Southwest Road (now Fujian), and his neighbors all know how to make tea. After the old man is free, sometimes he returns to Beijing, and his family is in Yangzhou, the house is clean, and he also loves to study the details of roasted tea. Today, the old man will tell you about roasted tea. ”

Su Song pointed to a bamboo basket like a big birdcage on the desk and said: "This thing, in the mouth of the Tang people 6 feathers, is called 'Yu', which means to educate tea, and we Song people call it a roasting basket." You see, in the middle of this cage, there is a partition, and when the tea is raised, the tea cakes are wrapped in calamus or bamboo leaves, and placed on the partition. Place this stove under the plate. The outside of the basket is covered with plantain leaves or bamboo leaves. ”

When he said this, he ordered the scholar to bring it to the stove, pointed to the remnants of the charcoal fire inside, and said: "The charcoal used to raise tea is very particular, and there are cooked charcoal, raw charcoal and pure ash. The red-hot charcoal is cooked charcoal and must be placed in the middle of the furnace. A circle of unlit raw charcoal is placed around the cooked charcoal, and the cooked charcoal and the raw charcoal are covered with a layer of ash left over from the burning charcoal, so that there will be no smoke rising in the furnace and the tea cake will not be smoked. Asa, you set up the stove, as I said. ”

The scholar named "Ah Kasa" went to the courtyard with the stove basin, lit some of the charcoal, and put it properly according to the pattern of cooked charcoal, raw charcoal, and clean ash, and then came back to move the charcoal basin into the lower layer of the roasted tea bamboo basket, and covered the basket with a layer of banana leaves.

About the tea effort, Su Song opened the banana leaves, opened the basket door, and tried it first, and then beckoned Yao Huan and said, "Mrs. Yao can personally test the temperature of roasted tea." ”

Not hot, one could even say, not hot.

"Su Gong, the younger generation feels that the temperature is about the same as that of human hands." Yao Huan said.

Shao Qing also stretched out his hand to try, and his feelings were the same as Yao Huan's.

Su Song said: "That's it. Hojicha, the main purpose is to make the tea cake dry and long-lasting, if the roasting is too strong, the cake will be dim, and a good tea cake will be abandoned. ”

"I see," Yao Huan realized, "No wonder it's called Yucha, not roasted tea, roasted tea, a Yuzi, showing the meaning of gentleness." If the open flame is used to bake, won't it become the method of burning meat in my restaurant? If the smoke rises, it becomes smoked fish and smoked meat. ”

Shao Qing couldn't help but want to laugh.

She is really, three sentences inseparable from food.

Su Song was also angry, and the wrinkles at the corners of his eyes became more and more kind: "Yao Niangzi is funny, it is true." Therefore, the old man guessed that the method of roasting tea is not the right way for you to roast beans. ”

Yao Huan nodded. It is indeed not a way, this kind of device, in fact, to put it bluntly, is the back-end process of the Song Dynasty tea cakes that have been deeply processed such as steaming, even if the temperature of the electric stove after drinking the leaves to make tea in later generations is much higher than it, not to mention the temperature required for roasting coffee beans.

In this kind of roasting basket, there is no caraking reaction at all, what is the difference between roasted and unroasted?

Shao Qing was also a little embarrassed and said: "The younger generation originally thought that roasted tea was some complicated mechanism, stirring the tea cakes, rolling over the fire......"

Su Song waved his hand and explained: "Oh, it doesn't matter, the sky is high and the earth is wide, the scenery is very different, and it is thousands of miles away without understanding the mystery, so there is no need to be embarrassed." When the old man went to Liao, whether at the banquet or in the post station, he made a lot of jokes because he didn't know how to use the utensils. ”

The old gentleman said frankly, but Shao Qing felt a sigh in his heart. He has been in Kaifeng for so long, and he is still very sensitive when he hears the word "Liaoguo".

His gaze moved, and he suddenly bumped into Yao Huan's eyes staring at him, and that look was full of surprise.

"What's wrong?" Shao Qing asked her in confusion.

Yao Huan smiled: "Iron bucket, blower...... Mr. Shao reminded me. ”
