This has been a difficult list to write because the prices of these items vary from season to season. However, despite that, these 10 foods are generally the most expensive things you can eat. The ordering is based partly on price and partly on how luxurious they are considered to be.

1. Beluga Caviar [Wikipedia]

Beluga Caviar is the most expensive food item in the world, costing up to $5,000 per kilogram. Caviar is fish roe (eggs) and this particular brand comes from the Beluga Sturgeon, found mostly in the Caspian sea. It can take up to 20 years for a Beluga Sturgeon to reach its maximum size and they can weigh up to 2 tonnes. The eggs are the largest of the fish eggs used for caviar. Beluga usually ranges from purple to black, the palest being the most expensive. Beluga caviar is generally served on its own on small pieces of toast as it needs no additions of flavour to improve it. If you have not experienced eating caviar, when you bite down each egg pops and releases a slightly salty-fishy flavour.

2. Saffron [Wikipedia]

Saffron is the most expensive spice in the world, reaching prices beyond $2,000 per pound (depending on season). Saffron is the three stigmas and style of the crocus flower. Each stigma and style must be picked by hand and it takes thousands to make a single ounce of the spice. Brightly yellow in colour, the spice is used for colouring and subtle flavouring of food. It has a bitter taste and a hay-like fragrance.

3. White Truffles [Wikipedia]

Truffles are from the underground ascomycetes family (tubers) and are reputed for their high prices. It has an odour similar to deep fried walnuts which is extremely pungent to some people, causing a reeling effect. Interestingly, some people are unable to detect the odour of truffles (which is possibly to their advantage!) The white truffle is the most expensive of the family. They are generally served sliced into extremely thin slivers on top of other food and are frequently suffused in oil for sale as truffle-oil.

4. Kobe Beef [Wikipedia]

True Kobe Beef () raised from the black Tajima-ushi breed of Wagyu cattle is produced only in Hygo Prefecture in Japan. It is bred according to secret, and strict traditions. It is fed on beer and grain and produces meat so tender and fatty that it rivals foie gras in texture. The beef can cost up to $300 per pound. This breed of cow is genetically predisposed to intense marbling, and produces a higher percentage of oleaginous, unsaturated fat than any other breed of cattle known in the world. Another special trick in the production of this meat is daily massages by the human owners. I must confess to being a little envious!

5. Birds Nest [Wikipedia]

The nests in question here are produced by a variety of Swifts, specifically Cave Swifts who produce the nest by spitting a chemical compound that hardens in the air. The nests are considered a delicacy in China and are one of the most expensive animal products consumed by humans. It is generally served as a soup but can also be used as a sweet. When combined with water, the hard nests take on a gelatinous texture. My own experience of Birds nest was in a pudding called Birds Nest and Almond soup the nest was dissolved in almond milk which was served as a sweet soup. The nest tasted musty and had the texture of snot.

6. Fugu [Wikipedia]

Fugu () is the Japanese word for pufferfish and is also a Japanese dish prepared from the meat of pufferfish. Pufferfish are deadly and if the fish is prepared incorrectly it can lead to death (in fact there are numerous deaths reported in Japan each year from the consumption of this delicacy). One pinhead of the pufferfish poison is sufficient to kill a full grown adult male human. It has become one of the most celebrated Japanese dishes. In order to prepare the fish for human consumption, a Japanese chef must undergo rigourous training and certification. It is normally prepared in such a way that a tiny amount of poison is left in the fish as the poison gives it a slightly numbing and tingling effect.

7. Foie Gras [Wikipedia]

Second to caviar, foie gras is one of the finest western foods available. It is the liver of ducks (foie gras de canard) or geese (fois gras dOie). It is produced by a method called gravage, which is force-feeding of the animal of grain via a tube down the throat. Ducks and Geese have an anatomy that makes this painless. The liver expands to many times the normal size and contains a great deal of fat. The texture of foie gras is very similar to that of butter with a very earthy flavour. Foie gras is generally eaten as a raw pate, but is can be lightly cooked to give it a greater depth of flavour. Unfortunately this delicacy is surrounded by controversy and the sale and consumption is banned in some American cities (such as Chicago). It is freely available in all parts of Europe and the rest of the world.

8. Lobster [Wikipedia]

Lobsters form a large family of marine crustaceans that nets a $1.8 billion for the seafood industry every year. They have a close family relationship with fresh water crayfish. Lobsters live on rocky, sandy, or muddy bottoms from the shorelin
