Bizarre Foods in Chile
I think this was it (from his blog). It was alive too.
"I even found an edible invertebrate called a piure that I had never even heard of, let alone ever saw. The scene that made it into the show is extraordinary. Truly the most bizarre food we have ever encountered."
Found the following in Wikipedia. I liked the description of "rubber dipped in ammonia". Yummo!!!
Various Ascidiacea are used as food. Sea pineapple (Halocynthia roretzi) is cultivated in Japan (hoya, maboya) and Korea (meongge) and, when eaten raw, has been described by Lonely Planet as tasting like "rubber dipped in ammonia". The peculiar flavor is attributed to an unsaturated alcohol called cynthiaol.
Microcosmus sabatieri and several similar species from the Mediterranean Sea are eaten in France (figue de mer, violet), Italy (limone di mare, uova di mare) and Chile (probecho), consumed both raw and used as ingredients in seafood stews like bouillabaisse.
