In the Middle Ages, Europeans sincerely believed beaver to be a real fish (like any water bird). In the XVII century, the bishop of Quebec, at the request of the flock, requested his superiors to allow beaver meat on Fridays during Lent. Attention: since the semi-aquatic rodent was a skilled swimmer, the Church stated that this beaver is a fish - and since he is a fish, and the fish is not forbidden, then you may fry the beaver during Lent. Profit!
By the way, one more interesting gastronomic fact about fish and how it was used at that time (during the Middle Ages there was no electricity and no fridges). Fresh fish was being deprived of all excess and dried to keep, and before cooking it was soaked and “beaten” with a hammer.
