All of my grandparents are Norwegian (and going back 700+ years). My one grandfather had dark olive skin, jet black hair, and dark brown eyes. My dad always figured he had the genes of some beautiful Mediterranean slave girl brought back from the Vikings.
That was, until he visited northern Norway and the Sami villages. Very dark features there too.
Being of Italian descent there isn’t anything I dont like except scungilli (large snails) and anchovies. Sardines I really like especially as an adult. Recently got adventurous and bought a can of fried mackerel imported from Latvia. Never tried it like that before but it was very good. Most young people wouldn’t care for it however.
