Call it a delicacy, unusual, strange or down-right gross, some rare foods can turn your stomach or delight the palette. You may have tried escargot, haggis, intestines, liver or tongue but that's nothing compared to these rarities.

Ever tried hedgehogs or cock's combs? Who knew that shark fins make decadent soups... they can be found in Hong Kong, Singapore and North America. Australian's consider kangaroo tail ragout and sugar ants to be a real treat. Camel hump meat which is extremely tough and sour-tasting has been enjoyed by Arabs and western Chinese for years. And although elephant meat is tough, it's feet and trunk surprisingly are not.

One item I think is truly bizarre and has garnered the name of "Caviar of the East" -- bird's nest soup. Served in China for over 400 years, the primary ingredient are saliva nests built by cave swifts. Among one of the most expensive animal products consumed by humans it is believed to aid digestion, raise libido, and even alleviate asthma as it is dissolved in water to create a gelatinous soup. In Hong Kong, a bowl of bird's nest soup would cost between $10 and $30, a kilogram of white bird's nest can cost up to $2,000 per gram, and a kilogram of red bird's nest for as much as $10,000!

I've tried alligator, rattlesnake, and rocky mountain oysters but that's the extent of my culinary tasting prowess. There are rare culinary dishes all around the world to test your boundaries and your wallets.
