It's known as the black gold of Périgord or the black diamond of gastronomy. It hides under the wild oak and hazelnut trees of the Dordogne valley: the Périgord black truffle.

Or how to combine tourism and cuisine.

What are Périgord black truffles?

Cavorting with a dog or pig 

The pigs are replaced by dogs trained to find truffles in a truffle field. Once he has spotted one, he scratches the ground. This is when the "caveur" comes into play: the truffle farmer digs into the earth with a "cavadou" or truffle pick. This instrument enables him to extract the black diamond very delicately. Harvesting takes place in the morning or evening.

Some use another technique "to find the truffles you're looking for. All you have to do is spot the little bumps on the surface of the earth that are formed by the growth of truffles. It takes observation and practice, but this method is also used in the Dordogne valley.

How do you choose a good Périgord truffle?

First clue: are the truffles ripe?

When the truffle is ripe, it is a beautiful black colour. But for it to be perfect, it must also be streaked with white veins. If you are presented with a grey or white truffle, you can set it aside: it is not ripe. And if it's completely black, that's not a good sign either: it's had a cold snap.

Second clue: is the truffle clean?

Soil can hide imperfections: don't hesitate to choose truffles that have been brushed. 

Third clue: is the truffle firm?

Once you have observed how the truffle looks, you can touch it: it should feel firm under your fingers. If it's too soft, it's not a good sign: it must have frozen.

Fourth clue: do truffles smell good?

Now is the time to smell the truffle and take in its distinctive aroma. Don't hesitate to ask the truffle grower for the opportunity to smell.
