To preserve the truffle’s fragrance, you should store it in the following manner:
In the refrigerator: : in a sealed container (a jar or Tupperware), wrapped individually with a piece of absorbent paper (to be changed every other day) or covered with rice. The rice will then absorb the truffle’s aromas and can be used, in particular, to make a delicious truffle risotto.
If you want to make eggs with truffle, it’s a smart idea to put store the truffle and eggs together in a sealed container one or two days before cooking so that the eggs will absorb the truffle’s aromas. This will make the truffle flavour in a dish like a truffle omelette that much stronger..
In the freezer: in a jar or in a freezer bag is the easiest way to store a fresh black truffle for longer (one year maximum). However, it’s important to note that freezing also changes the truffle’s texture (which becomes spongy) and aromas. Because of this alteration, the frozen truffle can only be used in sauces, omelettes, and recipes cooked with truffles. The frozen truffle should not be thawed before using it; you can simply grate the frozen truffle over your warm dishes. Another tip: you can create truffle-flavoured butter and freeze it.
