If we are what we eat, then watch out for these strangely revolting things that people actually enjoy.
Fried spider is a delicacy in Cambodia. This specialty snack is a popular attraction for tourists. The spiders are bred in holes in the ground in villages north of Skuon, or foraged for in nearby forestland, and fried in oil. The spiders are a species of tarantula called "a-ping" in Khmer and are about the size of a human palm. At nicer restaurants, the cost is $4.25 for 4 spiders.
Silkworm aka Beondegi
Beondegi, boiled silkworms, is a popular snack in Korea. They are served warm in a giant pot and soaked in boiling water, where the vendor will spoon a handful of them into a cup for you. It's only $3 for a healthy-sized portion that's definitely enough to make you feel nauseous.
Rotten Shark aka Hákarl
Kæstur hákarl, Icelandic for "fermented shark", is a national dish in Iceland consisting of a shark which has been cured with a particular fermentation process and hung to dry for up to 5 months. Kæstur hákarl has a strong ammonia-like smell and fishy taste. Kæstur hákarl is sold in Icelandic grocery stores and is eaten all year-round.
