Polish people love their Beaver Tails. However, they are not the pastry version found at Rideau Canal in Ottawa, Canada. They are actually from the living animal. 300 years ago, beavers were considered to be part of the fish world by Polish people. Compendium ferculorum, albo Zebranie potraw (A Collection of Dishes) is a cookbook by Stanisław Czerniecki written in 1682 with the recipe for the Polish dish. Lucky for the beaver, it has become somewhat of an endangered species in Poland. Can I please get some Nutella and sugar on my tail, please! Like the dodo bird, this recipe has fallen by the wayside.
