A truffle can have a shelf life of up to 2-3 weeks, however each day they lose a little moisture and aroma and are best used fresh and within 10 days of harvest. To keep your truffle in the best possible condition, store the truffle in an airtight container in the fridge with a small piece of kitchen towel to absorb moisture. Replace the kitchen towel daily.
Alternately, you can store the truffle in an airtight container with risotto rice or raw eggs. The truffle aroma and flavour will infuse into the rice and through the egg shell into the eggs. After 3 or 4 days, you can make a beautiful dish from the truffle-infused eggs or risotto.
The beautiful and volatile truffle aroma is best preserved by cooking with a gentle heat, or by shaving fresh over a hot dish. The truffle flavour is brought to the fore when paired with creamy and simple foods such as soft cheeses, eggs, butter, mashed potato risotto and creamy soups or pasta.
