That's pretty expensive stuff to get your hands on before
learning how to cook with them and what to use them in.
In our case we could either pay the gas bill this month, or get truffles! Wife frowned at me there, guess I have to go with the gas bill.
Maybe find a nice five star restaurant in your area that has dishes made with truffles and order them. It will give you a good idea of what they taste like, how they use them, and whether or not you like them enough to spend the money on them and give it a try yourself.
