[The ingredients are good to eat, and the ingredients used in the secret sour plum soup are as follows]

After the electronic tone, the system starts to display words:

Ume: It has the effect of relieving heat and relieving cough. It is the main ingredient of the secret sour plum soup.

Selected fresh black plum fruits ripened in Ji'an, Zhejiang Province in mid-May, roasted at 45 °C for two or three days, then stuffed for two or three days, and then after the plums turn black, then mixed well with special cedar charcoal ash, and finally grilled dry with charcoal fire. The charcoal plum obtained in this way has a unique flavor.

"It turned out to be charcoal black plum, no wonder the secret sour plum soup has a very light wood-fired fragrance. Bai Xiaobai muttered.

In the Chinese Pharmacopoeia, there are two kinds of black plum processing, one is vinegar black plum, as the name suggests, it is made by mixing rice vinegar and simmering, and the other is the charcoal black plum method provided by the system.

Vinegar black plum, the quality is soft and moist, slightly vinegar, because the cough effect of the lungs is stronger, so the medicinal use is the majority, the charcoal black plum, the quality is more brittle and hard, the surface is also burnt black, the taste is sour, more suitable for eating as an ingredient.

Of course, these two kinds of sour plum can be bought in general pharmacies, and Bai Xiaobai used to make homemade sour plum soup in the summer, using charcoal black plum.

The black plums provided by the system are good, all of them are selected, like the size of a ping pong ball, but the preciousness is a little worse.

However, the next words of the system directly made Bai Xiaobai speechless.

The system continues with the following words:

Tangerine peel: The system selects the best red skin Xinhui tangerine peel in the Longqing period of the Ming Dynasty, which has been perfectly preserved for 450 years.

This is the only one in the world, the hundred-year-old tangerine peel, rich in orange volatile oil, fragrant, long smell, is one of the key ingredients of the secret sour plum soup.

After seeing the tangerine peel of the system.

Bai Xiaobai's mouth opened slightly, and the whole person stood on the edge of the cupboard, speechless.

Tangerine peel has Sichuan tangerine peel, Fujian tangerine peel, Guangchen peel, etc., among which Guangchen peel is the most, and in Guangchen peel, Xinhui origin is the authentic and local product.

Xinhui tangerine peel, well-known at home and abroad, is one of the three treasures of Guangzhou, as early as the end of the Song Dynasty has been recorded, is the north and south, the south of the Guangzhou region of hard currency.

According to the different processing time, Xinhui tangerine peel is divided into citrus green peel (green peel), slightly red peel (yellow peel) and big red peel (red peel)

Green skin and yellow skin are mostly used for medicinal purposes, and large red skin is the best to eat.

The system uses the big red skin of Xinhui tangerine peel, that is, it is still a four-hundred-year-old Xinhui tangerine peel, a proper local tyrant!

I don't know how the system was preserved by the ancient tangerine peel.

Bai Xiaobai has heard such a sentence.

1000-year-old ginseng, 100-year-old tangerine peel.

Whether the growth cycle of ginseng can reach 1,000 years has always been debated in this academic community, but the 100-year-old tangerine peel is real.

The longer the tangerine peel is preserved, the more the substances in the aromatic oil continue to change, and its edible and medicinal value is gradually reflected.

However, correspondingly, the older the tangerine peel, the more difficult it is to preserve, especially the mature red peel, because of the high sugar content, it is more likely to be moth-eaten or naturally powdered, so even if the tangerine peel in ordinary retail homes is sealed and preserved after drying, it usually cannot be completely preserved for more than ten years.

Tangerine peels that can be preserved for twenty or thirty years, or even a hundred years, are processed by special methods.

For example, the century-old brand Chen Liji's '100-year-old tangerine peel', because of its unique processing method, has a long history of culture, and the quality is in the same line, it is rumored that it has been more than 170 years, and has been designated as a royal tribute by the Tongzhi Emperor of the Qing Dynasty, which can be called a model of Chinese medicine.

Rare is expensive, more than 50 years old tangerine peel one gram is worth thousands of gold, '100 years old tangerine peel' is even more hard to find.

After the establishment of the new Huaxia Kingdom, Chen Liji's rare "100-year-old tangerine peel" has been enjoyed, and there are only 3 to 5 people recorded so far, and even the leaders of the Huaxia Kingdom may not be able to eat it.

In 1954, when Chen Liji, a time-honored Chinese medicine shop, implemented a public-private partnership, Li Langru, the "head" of Chen Liji at that time, had to take one or two Chen Liji's "treasures of the town" - "100-year-old tangerine peel" every year to Song Qingling and He Xiangning. In 1985, Chen Liji held a celebration of the 385th anniversary of its founding, and in order to thank Fok Yingdong, vice chairman of the National Committee of the Chinese People's Political Consultative Conference, and Li Xiongcai, a master of the Lingnan School of painting, for their love for Chen Liji, Chen Liji's descendants also presented a collection of century-old tangerine peels to the two. At that time, Fok Yingdong also praised that "this century-old tangerine peel is more precious than gold".

In addition to Chen Liji, there are also two treasure-level tangerine peels presented by Chen Liji to Xinhui Exhibition. In addition, the century-old tangerine peel of the Museum of Traditional Chinese Medicine of the Imperial University of Chinese Medicine was also donated by Chen Liji. Now there are only these three places in the world that have "100-year-old tangerine peel".

I didn't expect that the tangerine peel provided by the system now is actually the Xinhui tangerine peel during the Longqing period of the Ming Dynasty, after 450 years of vicissitudes, and I don't know how many generations have passed, its preciousness directly kills Chen Liji's tangerine peel for more than 170 years.

It is no wonder that when boiling the secret sour plum soup, only a fingernail-sized tangerine peel is used, and the secret sour plum soup smells fragrant, with the unique fragrance of tangerine peel.

Bai Xiaobai picked up a jar of 400-year-old tangerine peel in a glass bottle, the tangerine peel in this jar looked very ordinary before, but now it is a jar of golden tangerine peel in his eyes.

Ordinary tangerine peel is worthless, and a hundred years of tangerine peel is better than gold.

The tangerine peel the size of a fingernail used to boil a pot of secret sour plum soup is close to 0.5g, and according to the current market price, it will cost at least thousands of yuan.

No, it should be a priceless rare ingredient in the market.

If you can auction this glass jar of 400-year-old tangerine peel and buy a house and a car, it will be enough, and you may even have more than enough for your wife.

And if it is auctioned, it will definitely cause a sensation in the whole of China, and the headlines of major media will rush to report, and it may even affect Hong Kong, Macao, Taiwan, and even overseas, and the popularity of your own small store will definitely jump wildly.

However, Bai Xiaobai is just pure YY, not to mention that the system does not agree to auction the tangerine peel for the past four hundred years.

Even if the system really agrees, Bai Xiaobai does not dare to auction rashly, and if he does it well, he will gain fame and fortune and walk to the pinnacle of life. After some government personnel knew, they were even exempted from 500 yuan + a certificate, and went to the door to directly ask where the 400-year-old tangerine peel was found, whether it was dug by tomb robbery, if it was handed down by the ancestors, is there anything to prove that this tangerine peel is yours, otherwise this is the country's ......

"By the way, the system, this tangerine peel is good, and it is indeed very fragrant, but it has been preserved for 450 years, which does not comply with the current food hygiene law. Although the hundred-year-old tangerine peel in a glass jar seemed to be quite well preserved, Bai Xiaobai had no bottom in his heart, and he couldn't help but ask the system.

After all, since he opened the store, he has always adhered to the principle that the ingredients must be fresh, and he can't fool customers with rotten vegetables and rotten meat, which is what his father repeatedly emphasized before his death: he would rather spend a penny more than choose cheap rotten ingredients.

It is true that you can save a lot of costs at the beginning with cheap or inferior rotten dishes, but the customer is very shrewd, and after eating once, he will never care about it again, so in the end, it is still himself who loses, and it is simply more than worth the loss.

The cold electronic sound of the system quickly replied to the safety problem of tangerine peel for 400 years.

[After the Xinhui tangerine peel is dried, the system uses high-tech physical vacuum anaerobic preservation for 450 years, during which no special processing method is used, no chemical preservatives are added, and the taste is pure and natural. After a set of strict testing and control, the 400-year-old tangerine peel complies with the current health food law of Huaxia, and there are no harmful substances, so the host can use it with confidence. 】

The black technology of the system, Bai Xiaobai has long been taught. Since the tangerine peel of 400 years ago has been strictly tested, he is also relieved.

But then again, the system is really getting better and better!
