The Most Weird Food In The World

1. Balut, a developed duck embryo boiled alive and eaten in its egg. Really common  in Southeast Asia and also often served with beer. The ideal balut is 17 days in the Philippines, but Vietnamese people prefer the 19-21 days old ones.

2. Casu Marzu, (means rotten cheese) a traditional sheep milk cheese from Sardinia, Italy. The cheese makers set the cheese outside and allow cheese flies to lay eggs inside of it. The larvae are breaking down of the cheese's fats and fermenting it.

3. "Thousand Year Old Egg" from China, made by preserving eggs in a mixture of ash, salt, quicklime, rice hulls, and clay for several weeks or months.

4. Smalahove, also called Skjelte, a traditional smoke or dried Norwegian dish made from a sheep's head. Originally, it was eaten by the poor only.

5. Sannakji is a raw Korean dish that consists live octopuses with sesame and sesame oil. It looks safe but the little tentacles may choke you to death if theyet stuck in your throat.
