Get a son in one fell swoop
Napoleon fought in all directions for a long time, but suffered from no heir to inherit hegemony. But after eating truffles and cooking chicken, he got a son in one fell swoop, which also proved the Millennium rumor that truffles can enhance glory. The magical science of truffles may not be verified, but the brilliant aura that has been circulated for thousands of years has already sublimated the taste and become a symbol of dignity.
There is no more legendary ingredient than truffles. This long-buried wild fungus is naturally rich and fragrant. Any restaurant willing to introduce it is equivalent to lighting up the signboard, so truffles are also called "black diamonds on the table". At this time, truffles are not only a long fragrance, but also make diners immersed in the infatuation, which is hard to extricate themselves.
Three Great Foods in the World
People have been eating truffles for 3000 years, but it was not until the17th century that it really became a seasoning sacred object. Before truffles became popular, Europe was a golden and rich oriental spice world, with pepper and clove dominating each other. Therefore, under the leadership of the French, Europeans are more and more eager for natural fragrance, and truffles are extraordinary and rich in flavor, and finally get attention.
After the 20th century, Italian truffles appeared, and the output of truffles was scarce, making it difficult to transport. The truffle price rises, and the delicious myth climbs to the peak.
/kloc-The 20th century was the heyday of black truffles, and at least one dish on almost all formal dining tables was dominated by black truffles. Europeans list truffles, caviar and foie gras as "three great delicacies in the world".
Why are truffles so precious?
Up to now, most wild fungi stubbornly refuse human domestication. They are out of tune with this genetically modified era. They grow in the soil of 40 cm to 1 m, so the fragrance is more preserved and the absorption of nutrients is more complicated, which leads to the ever-changing smell.
Truffles cannot be planted. It cannot produce carbohydrates needed for growth through photosynthesis, but can only obtain nutrients through the roots of tree species, and these trees can also absorb water and minerals absorbed by truffles from the soil through the roots. Therefore, a farmer can only plant oak, pine or oak infected with truffle spores, and then wait patiently, ranging from 5 years to 10 years, in order to gain something. Of course, it is also possible to get nothing. There are too many unpredictable factors in the growth of truffles. Rain, soil, minerals, tree species and soil pH can't change at all.
China truffle
In China, truffles can only grow in a few places, such as Yunnan and Liangshan, and their precious value is not lost to Cordyceps. The season of fresh truffles is very short, only about three months a year.
Yunnan has special truffle hunting grounds and truffle hunters, and of course truffle dogs are indispensable. The soil near where truffles grow will smell of truffles, and truffle hounds find truffles by the smell of soil.
Difference between China Truffle and Western Truffle
According to the biological classification, truffle is also called truffle, which belongs to fungi, Ascomycetes, Cladosporium, Cladosporium, Truffle and Truffle. The blood relationship is closest to Morchella. Up to now, 16 species of truffle have been reported in China, and 12 species are distributed in Yunnan, among which "Indian truffle" is the most. Genetic map analysis shows that the similarity between "Indian truffle" and French black spore truffle is above 96%, which belongs to sister relationship.
What does 96% similarity mean?
From the appearance, the two need to be distinguished under a microscope. There is almost no difference in flavor and nutritional value.
Some people say that Yunnan truffles are not as good as French truffles. Professor Liu Peigui, a mycologist from Kunming Institute of Botany, Chinese Academy of Sciences, told a story: once a French friend brought some black spore truffles, and Liu Peigui mixed them with Yunnan truffles and cooked them in the same way. However, this French friend can't see the difference.
Now people have realized this, so according to the natural growth of truffles, they made a periodic table of elements.
Periodic table of truffle elements
Fungi have had hallucinogenic effects since ancient times, which can be seen from the way they are excavated. This fragrance is originally musk. Eating truffles stimulates our own hormone secretion to some extent, which makes you fascinated and addicted.
Lin Yutang said:
"Out of love, we eat crabs;
We often eat grass roots because of necessity. "
People in China don't know how to eat healthily. Dual diet structure (plants and animals) leads to three highs: high protein, high fat and high blood sugar. Now is the era of fast food, everyone is eating hormones and fertilizers, and many diseases are eaten. It is time to consider healthy eating habits.
Fungi have the advantages of both meat and vegetables, and are rich in vitamins, minerals and trace elements. The content of protein greatly exceeds that of ordinary vegetables, and at the same time, it avoids the harm of high fat and cholesterol in animal food. The World Food and Agriculture Organization (FAO) advocates that a reasonable combination of meat dishes, mushroom dishes and vegetarian dishes is the best dietary structure.
From a health point of view, truffles are the first of all wild fungi. It has the highest and most comprehensive nutritional value, and contains 18 amino acids, small molecule protein, and more than 50 physiologically active components such as unsaturated fatty acids, sphingolipids, catalpol and trace elements. Among them, sphingolipids have attracted extensive attention in recent years. They can repair damaged neurons, treat diabetes, prevent and treat Alzheimer's disease, prevent and treat cardiovascular sclerosis in middle-aged and elderly people, and also have a certain inhibitory effect on cancer cells.
