"Slightly Salted Whitefish" in Finland

Strangely, this cold whitefish served at a catered business lunch seemed to have a bit of the dill weed taste that is common in herring up here, leading me to think that this was also a local thing. But they also offered a "wasabi dressing," which changed that perception. Fortunately, there was hardly any wasabi taste, and the sauce was sometimes needed given it was sometimes more than "slightly salted."
