La truffe, le diamant noir


Of course, generations of truffle growers have studied it, passed on tips and tricks.
Most of the keys to its breeding have been laid down: it grows in limestone soils on the causses of Lalbenque, Limogne-en-Quercy and Lot, over a shallow depth (10 to 30 cm), in rather airy, draining soils and with a pH close to 8. But what else?
Well, that's where family secrets are whispered, but not shared.
Where the truffle becomes a heritage: that of the lands and house secrets.
The truffle is a flavor and a smell
First a smell. When she is ripe, it perfumes markets and kitchens. Some enthusiasts can even remain with their noses glued to it, like a divine addiction. The truffle is a charmer. Then she is a flavor that takes your taste buds to ecstasy, Do not be scarred by words. It doesn't take much to be happy and flavor an omelet, a brie, a small pot of butter, a cabbage or an aperitif. The little is its strength; the creamy makes its perfume, the time (a few days) makes its depth. So forget the price per kilo, think 100 grams and that's already a lot, think moments of culinary exaltation and it's huge. Imagine rare moments, which rhyme with rare product and the whole thing will create memories of a rare poetry.
The truffle is a know-how and a product of the land
The truffle tree, pubescent or green oak, is noticeable by the presence of a bare ground area around the trunk. This zone comes from the aggressive action of the mycelium.
The truffle is born in the ground around May-June, then develops during the summer months thanks to storm rains (especially in August). She begins to mature with the premiers cold autumn and harvested at maturity during the winter months.
Le limestone soil of the causses of Lalbenque and Limogne-en-Quercy lends itself very well to it.


How is the harvest going?
Cavage consists of extracting the truffle from the ground, when it is ripe, in winter, usinga dog ora trained pig. Unlike the dog, the pig is very fond of truffles. His master must ensure that he does not eat this precious mushroom. Failing that, you can also search for truffles usinga blue fly, specific. We follow it with our gaze and, in mild weather, when we see it land at the foot of an oak tree, the truffle is spotted and you can start digging. Truth or legend?
You still have to try, but the elders say they know how to do it.
Finally, do it with your own sense of smell, nose to the ground. It can work… but be careful not to be with a truffle owner. We have very short humor on the subject here….
Truffle, what is it?
