Where is the origin of truffles?
Truffles are distributed in Italian, French, Spanish, China, New Zealand and other countries. Among many kinds of truffles, French-made black truffles and Italian-made white truffles have the highest evaluation. The appearance of truffles in China is very similar to that of black truffles in France. The scales on the outer skin are relatively small, and the white stripes inside are relatively thin, mainly growing in the fibrous roots of pine trees. This truffle is also the name of China, mainly produced in Sichuan and Yunnan. Mature China black truffles have a complex mushroom flavor, which is an incomprehensible smell.
World-famous truffle producing area
1. Alba, Italy: rich in white truffles, it is the most famous and expensive white truffle producing area in the world. Usually, white truffles can be sold for tens of thousands or even hundreds of thousands of yuan per kilogram. At the beginning of October, the famous Arba Expo began. White truffles, like sacrifices, are carefully placed in the glass cover of each booth for pilgrims to worship.
Perigueux: It mainly produces black truffles. At the end of 19, the phylloxera caused devastating damage to the vineyard and the grapes died in a large area. Local grape growers chose to replant vineyards into oak forests, which created favorable vegetation conditions for the growth of truffles. At the same time, there is plenty of light and suitable rain, and it has gradually developed into a large-scale business.
3. teruel, Spain: After the end of the Spanish civil war, people found that black truffles could grow in the poor soil of teruel, so people began to vigorously develop the truffle industry. At present, truffles have become an important economic source in this area, but their fame is not as good as that of Italy and France.
4. Oregon, USA: Truffles also grow in Oregon, but the price is lower than that of European truffles. Oregon Truffle Festival is held on June 5438+ 10 every year, including truffle tasting and training hounds to find truffles. At present, truffles are another major industry in Oregon after wine.
5. Yunnan, China: Compared with the black truffle on the European food altar, the aroma and taste are much worse, and the price is several times different. But its low price and high cost performance make it easier for ordinary people to enter the family, so its market potential is also greater.
Why are truffles expensive?
Truffles need extraordinary growth environment.
Truffle is an annual natural fungus, which mostly grows under pine trees, oak trees and oak trees. Truffles are very picky about the growing environment. As long as the pH value of sunlight, water or soil changes slightly, they can grow. They are the only ones in the world that can be planted irregularly. Truffles will grow under one tree, but another tree that looks exactly the same next to them can. So far, people haven't. I don't know why.
Amazing way of harvesting
Truffles do not grow on the upper surface of the earth. We don't know where they grow. So every truffle hunter has a treasure map handed down from the family, which records the location, time and size of truffles discovered by parents. The process of finding truffles is very interesting. Hunters can only hunt with tools, mainly hounds and sows.
Sow: The accuracy is the highest, because the smell of truffles is very similar to that of male hormones emitted by boars, so sows have a special liking for truffles. Sows have a keen sense of smell, and they can smell truffles buried 25-30cm underground at a distance of 6m. But because sows are greedy for truffles, if they are not stopped in time, they will be eaten by sows.
Hunting dogs: In order to prevent truffles from being eaten by sows, people train hunting dogs to replace sows. A trained hound can sell for about $3,000.
How to buy truffles?
Before smelling the truffle, you can see if it is preserved in the soil of its origin. If you see naked truffles, most of them are not fresh and the fragrance is gone. When buying, one must smell the fragrance and the other must pinch the texture. It should be harder and better. If you cut the truffles, you will find that the texture is very fine and the quality is the best.
