I guess that makes me a European. I bloody love the pickled herrings. On work trips to Scandinavia there were often 3, 4 or even more varieties available on the breakfast buffets. Yum.
I wasn't madly keen on pickled herring when I moved to Sweden but I have to say I love it now. As you say there dozens of varieties. To be honest there's an eye watering number of ways they prepare herring, never mind just pickled.
