Robb Marrocco on Instagram: "I’ve eaten Surströmming, the Swedish fermented fish that’s banned in public places. It’s herring in a can left to ferment for quite a while. The smell is likened to ammonia, anchovies, and a garbage can. I Ate this almost 2 years ago and it was quite a challenge. If you wanna see surstromming espresso or fizzy surstromming, the schmatreon is your place to do that! #surstrommingchallenge #reaction #surstromming"
