A U.K. chef has unveiled what might be the world’s most expensive cheese sandwich, according to London’s Guardian newspaper.

He’s charging 111 pounds, or $176, for the stack of special cheddar blended with white truffles and topped with a sprinkling of gold dust.

Chef Martin Blunos displayed his creation at the Frome cheese show in Somerset.

A 750-gramme white truffle from northern Italy sold for 100,000 euros ($150,000) during an auction at the end of the 79th White Truffle Festival of Alba.

The Piedmont region, where Alba is located, is considered to have the best ‘tartufo bianco’ (white truffles) in the world.

According to The world’s priciest food list compiled by Fortune Small Business, a CNN magazine, world’s most expensive food is Edible gold leaf.

The edible gold leaf comes with a price tag of $15,000 per pound.

No worries, like calcium and iron, gold is actually a mineral that’s safe to eat although it’s not an essential part of the human diet ^_^

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.
