There are probably thousands of different ways to keep fresh truffles; and each one is always the best. But which one really IS the best? The truth? Roll each single truffle in blotting paper (toilet paper, newsprint...) and store the truffles in the vegetable drawer of your refrigerator. Change the paper at least once a day. This way, you can preserve a truffle's freshness for about one week. 
Perhaps you have also heard of storing truffles in a jar with rice. Do not do this! This method is a sure way for getting your precious food moldy within three days.
The same thing happens if you put truffles in oil. Never a good idea!
The Urbani Group always advises against freezing fresh truffles at home, too, because it's not possible to ‘flash freeze’ the way that industrial companies can do. On the contrary, home freezing takes a very long time and results in truffle spore breaking which causes the truffle to lose its taste and distinct fragrance. 
If you want to freeze truffles, our best advice is to prepare a sauce (with butter and Parmesan) for white truffles, and a different sauce (with olive oil, garlic, salt, and pepper) for black truffles. Then freeze the truffles in their special sauce. 
For further information on using truffles or cooking with truffles, contact the Consumer Service of the Urbani Group at 800 – 864179 or visit our Web site where you can find a professional place dedicated to ways of enjoying truffles to the highest level of gastronomy.

For optimum enjoyment of the truffle, take out the vacuum-packed container with the frozen truffles one half-hour before you plan to use them. Slice or mince the truffles while they still slightly frozen.
On our Web site, there are some recipes that can be used with frozen truffles; however not all recipes can. You must be careful to use frozen truffles only if the recipe specifically states that you can.

Their use is becoming more and more popular not only because of their affordability, but also for their ease of use. The Urbani Group always observes that you obtain the taste and fragrance of ‘the real thing’ only by using sauces made with fresh truffles.
The oil usually used for these sauces is not always of the highest quality; and it only worsens after the product's sterilization. To maximize the fresh taste, it is best if you drain the sauce's oil and replace it – measure for measure - with one of the best extra virgin olive oils that you have. Add salt and pepper to taste. If you must use the sauce for pasta, we advise that you add more oil on the pasta, thus giving it a more tasty result. Of, if you prefer, if you have some crostini, add two-three drops of vinegar, and a spoon of lemon juice or dry white wine to the sauce. 
If you are cooking meat or fish courses, then add the truffle sauce at the end of what you are preparing.
