|Traditional method (before the refrigerator) today passed. Truffles were put inside a glass jar full of rice.||It absorbs the moisture released from the truffle and decreases the air inside the jar.|
The rice used was integral, it had a layer of unsaturated fats outside that solubilize the truffle aromas, then being able to be reused in the kitchen so “truffled”.
|The rice absorbs too much the aroma and day by day it dries the truffle excessively.|
|It’s the best way to preserve the fresh truffle.|
Duration: 7/20 days depending on the degree of ripening and species.
