Am a complete truffle addict and have been through one oil after another-looking for a good one- but the search has ended. I have found a GREAT one. Both the black and white are excellent(tho I confess to having a preference towards the more rustic black)exuding rich truffle flavor. I am now even sprinkling it over popcorn topped with parmesan cheese-yummmmm. Can be ordered on line at www.jrmushroomsandspecialties.com.
