Plokkfiskur is one of Iceland’s oldest delicacies, with every Icelander having fond childhood memories of. It is in fact simple. Use delicious bits of fresh white fish, mash it together with steaming-hot potatoes and a bit of butter and milk, season to taste, and you’re good to go.
Fish tongue is in fact "cod" tongues, quite commonly eaten in Newfoundland and Scandinavia. The “cod tongue” is actually a somewhat gelatinous Y-shaped morsel of flesh from the jaw or throat area of the cod. It has a succulent, soft centre and a delicious meaty taste.
