How does Ponticelli know when the truffles are ready? The first sign is that when the truffle spore is active, it kills the grass around the base of the tree, he told me. Some truffles will crown the surface, but most will be buried in the soil. His dogs can find truffles buried up to 7 inches deep.
Ponticelli has scent-trained his dogs, Labradoodles in his case although many breeds can be trained, so they will only find truffles that are ripe. “Each dog has a different way of telling you he’s found a truffle. Some dig, some sniff, you have to learn your dog,” said Ponticelli. And yes, if you’re not quick enough, your dog just might eat that truffle before you can snatch it away.
Ponticelli has about 30 acres of truffle orchard with around 500 trees to the acre. He’s hoping that when the trees mature, his crop will yield an average of 75 pounds of truffles per acre. Right now he’s not harvesting anywhere near that amount and most of his truffles go to his restaurant clientele.
Fresh truffles are not widely available. I found an Oregon truffle packed in a plastic clamshell filled with Arborio rice at Whole Foods Market. If you want a southeastern truffle, check the websites for Piedmont Valley Truffles, www.nctruffles.com, or Tennessee Truffle, www.tennesseetruffle.com, and call for availability. The cost should be in the neighborhood of $40 to $60 an ounce, and the truffle will have a shelf life of about two weeks.
How do you make the most of your expensive purchase? Ponticelli packs a sealable plastic container with a dozen eggs and a truffle and leaves it overnight. The truffle aroma penetrates the egg shells and he ends up with truffle-scented eggs. You can do the same thing with any variety of rice. And you still have your truffle to garnish the cooked eggs, rice or some other dish. Black truffles should not be cooked, but simply chopped or shaved to garnish other dishes.
And what about truffle oil? Many folks, including Ponticelli, say that most truffle oil never sees a truffle at all, but gains its flavor from an infusion of an aromatic organic compound that’s derived from petroleum. It is possible to find truffle oil made with real truffles, but expect to pay handsomely for it.
