It's hard to say what is normal and what is weird where food is concerned - it all depends on the taste of the individual and which part of the world you come from. One person's nightmare is another person's delicacy. Here are a few of the strangest (or most normal) types of food from around the world.

Haggis (Scotland)

A world-famous dish, haggis is made from the parts of a sheep many people would throw away. The heart, lungs and liver are mixed together with onion, spices and oatmeal, then put inside a sheep's stomach and boiled for three hours.

Brain sandwiches (USA)

These are not as common as they were in the past, but in parts of Ohio you can still get fried brains served on hamburger buns. Brains don't have much flavour, so you eat the sandwiched with plenty of sauce.

Hakarl (Iceland)

This has been described as the most disgusting food ever. Made by fermenting a Greenland or Basking shark for two to four months, hakarl smells of ammonia (like the bleach used for cleaning). It's available all year round in Icelandic stores and often served in cubes on toothpicks.
