This is a truffle salt made with French sea salt and black summer truffle. Guérande salt is rated IGP which guarantees the quality of the salt. You can even added it to the water for pasta if you like.
The Guérande salt is neither treated or refined, so it is mineral rich. It is known for having less of a salty flavor than other sea salts which makes it a better flavor enhancer. That is why the truffle aroma and flavor stands out.
