I was watching the Japan episode of Bizarre Foods With Andrew Zimmern the other day, wherein Zimmern samples funazushi, an ancient preparation of sushi that involves packing a fish (eggs intact) with salt, then aging it for up to six years. Even the show's host wasn't a big fan, and he's enjoyed some unconventional meals. Still, he could appreciate the historical value of this Japanese delicacy. Are you adventurous enough to try it?
