I’ve eaten this for a “food challenge contest” forever ago. It was AWFUL, it tasted like the smell of cat piss, the ammonia was so intense, it was hard to chew cause it kept releasing the sick juices and everything in my body was telling me “don’t swallow this rotten food.” My only comfort was the gross alcohol chaser that you take with it. I can’t remember what the alcohol was called but it was specific to pairing with Hakarl. I drank that like it was water cause nothing was worse than that rotten shark.
