People in the Indonesian village of Tuban like to eat "ampo" -- a snack literally made from dirt:

Although there is no medical evidence, villagers believe the soil snacks are an effective pain-killer and pregnant women are encouraged to eat them as it is believed to refine the skin of the unborn baby.

There is no real recipe: makers of the snack use a wooden stick to pound the soil into a hard, solid mass.

Rolls of dirt are then scraped off the with a bamboo dagger, baked and smoked in large clay pot for half and hour and then they're ready to serve.

The food is said to have a "cool, creamy texture."
