Macadamia is the world’s most expensive nut. Native to eastern Australia and Indonesian Sulawesi, this nut is extremely hard to crack (it requires pressure of about 300 psi or 2000 kPa). Due to rather complicated production, the nut sells for 30-40 dollars per kilo on the international markets.

Spice Saffron, which is the stamens of the saffron crocus, has built a reputation for being more expensive than gold. Its high price stems from the labor input: only about 6 pounds (2,7 kilo) of saffron can be produced from each acre (0,4 hectare) of land, so the price per kilo goes as high as $6000.

It is a known fact that any caviar is an expensive treat, however there are stars too – almas caviar. This caviar is white, and it comes from beluga which is over 100 years old. Beluga sturgeon, the largest fish and only predator in the sturgeon family, can take up to 20 years to reach maturity. It is believed, that the whiter the caviar the older the fish and the more exquisite the flavor. Almas Iranian caviar is extremely expensive. It is sold only in 24K gold tin for $2000 per 100 gram.

The world’s expensive chocolate is Chocopologie by Knipschildt, a hand made chocolate with 70 percent Valrhona cocoa powder rolled over French Black truffle which costs $250 a piece, i.e. $2,600 per pound (453 gram).

If you don’t feel like eating pure chocolate you may top it with the edible gold flakes as offered by DeLafée, a Swiss company, or even get just the 99% pure gold flakes, without a chocolate, for $73.87 a gram.

To wash down all the above exquisite viands some may want to use the equally expensive liquid. Say, the world's most expensive beer, Belgian Vielle Bon Secours costing around $1,000 per bottle or about $78 per pint. It can only be found in a bar called the Bierdrome in London.
