| They're probably preserved in brandy or something. I don't know how
long they would last once opened. Probably a couple of weeks in the
refrigerator. The main problem isn't spoilage, but that they lose their
flavor quickly once opened. The flavor of preserved truffles is already
a lot less than when fresh.
Truffles are used pretty much as you would use any strong mushroom.
They're good diced in omelettes, in sauces (on pasta, meat, or
poultry), and they're delicious when incorporated into a meat pate or
terrine. The French make some delicious terrines with truffles and foie gras.
My opinion: preserved truffles aren't good enough to warrant the high
price. Fresh ones are even more expensive, but the flavor is worth
trying at least once. On the whole, though, I think they're overrated.
