White truffles are one of the most expensive foods in the world. White truffles, like diamonds, are rough and heavy in appearance before being processed, but once carved, they are as bright as beautiful diamonds. Marble-like lines, ivory patterns and intoxicating aroma can give people strong sensory stimulation.

In fact, truffles are a kind of natural fungal plants, which mainly grow under the soil near the roots of oak whiskers. But strangely, truffles can't be farmed artificially, and it's very difficult to find truffles, and only female pigs and dogs with strict training can smell them. It is said that the secret is that truffles contain alpha male hormones. It is believed that it is this smell that leads female animals to think that they are tracking their opposite sex partners.

Truffles are produced all over the world, among which the world-famous French "black diamond" black truffles and Italian "white gold" white truffles are the most expensive, and they are called the three treasures in Europe and America together with caviar and foie gras.

Truffles are mushrooms, which mainly grow in the soil under oak trees and beech trees, and have nothing to do with "pine". Different kinds of truffles are produced all over the world, such as black truffles with red stripes in Britain, purple truffles in Spain and matsutake in Japan, but French black truffles and Italian white truffles are the most outstanding in terms of rarity and delicacy. So far, there are no artificial truffles, only wild ones. Every year 1 1 month is the best month to collect truffles. In the process of looking for truffles, Italians will use the "loose dog" to find the traces of truffles by smell, and then dig. The French love to use "Xunsong Pig" and designate it as a boar, because the smell of black truffles is similar to that of sows in estrus. Unfortunately, "Xunsong Pig" has a low professional ethics and often steals his mouth by taking advantage of his work, so in recent years, the French have also switched to "Xunsong Dog" to do it for them. A trained "loose dog" can be sold for HK$ 27,000.

The taste and smell of white truffles are described as unique in the world: their appearance is not snow-white, but light brown, and after being made into dishes, they are dark brown and slightly red, which looks like raw beef slices at first glance; Its smell is quite strong; Its taste is somewhat like damp potato chips. After eating, the vanilla smell like garlic will remain in the mouth for more than fifteen minutes.

So it seems impossible to cultivate artificially now.
