A Hong Kong property tycoon and his wife have reportedly paid $160,406 for a huge Italian white truffle in 2006, which may be the world’s most expensive ever.

Gordon Wu and his wife outbid connoisseurs from France and Italy to win the 3.3 pounds Alba white truffle from an international auction, a spokeswoman for the Ritz-Carlton hotel, which hosted the Hong Kong part of the auction, said.

It was the second time Hong Kong bidders won a pricey fungus at the annual auction, held in Grizane, Italy and satellite-linked with Paris and Hong Kong.

In 2005, a group of bidders in Hong Kong paid 95,000 euros for a 2.7-pound truffle, a purchase later named by Guinness World Records as the most valuable truffle bought at an auction.

The High Roller sushi roll that sells for $1000 will be served at Koi restaurant in New York : It starts with marinated and poached fois gras that is covered with succulent Langoustine (lobster).

Finally, when the roll is served the Chef comes tableside to shave white Alba truffles and drizzle them with 100 year balsamic.
