Oddity Central introduces us to chả rươi, a popular street food in Vietnam. This omelet dish is high in protein because the principle ingredient is palolo sand worms (a species distinct from the sandworms of Arrakis). These marine segmented worms can be caught at sea or raised on farms. Then they are prepared into spicy dishes:
Before being added to the chả rươi omelet, the sand worms have to be boiled to remove their tentacles and fishy smell. The latter is also combatted by the zesty tangerine peel and all the herbs. Still, the taste of sand worm can be too much for some people, so over time a less hardcore version of chả rươi emerged, one which contains more pork than worms. But for true chả rươi fans, the original, more expensive version is the only real option.
In this video, the food vlogger Sonny Side travels to Hanoi and helps prepare a worm pancake. It looks good, but I prefer my gagh to still be wiggling.
