You can watch arctic explorer Brue Parry eat it in the far north of Greenland. It is a well made programme.

You can watch it for the next three weeks online.
Bruce Parry journeys to the far north of Greenland, home to the last traditional Inuit hunters.
Bruce experiences the realities of life - and death - on a seal hunt, and learns how climate change is threatening their ancient way of life.
But while global warming is causing problems for the hunters, it is providing others with new opportunities. As the vast Greenland ice sheet melts, new mineral riches are being revealed. Bruce works with a mining team who are about to strike it big. Greenland is changing fast - but will there still be a place for hunters in the Arctic of the twenty-first Century?
I think we are probably a lot more sqeemish about what we eat compared to our distant ancestors :)
As well as eyeballs are there any similar strange foods that you have had the opportunity to taste? What were they like to eat?
