The balut (picture link above)

It is a fertile Duck embryeo - generally eaten about days 14 to 20 - of the 21 day incubation cycle.

For cooking it is boiled. Native to the Phillipines, but now readily available in the USA.

Another delicious delicacy - from Mongolia
Fermented Horse Milk (Kumys - aka mare's milk)
bubbly with carbonation and alcoholic like beer (tastes like spoiled milk)

In Peru - deep fried guinnea pigs (tastes like chicken)

Also in Peru - a bubbly beer (sold in the countryside at farms with a red plastic bag flying on a pole) that is made from corn that is chewed by old ladies (grandmothers) and spit into a plastic bottle to ferment...aka saliva-fermented chicha...(smells like vomit)
