I've tasted beaver a couple of times, and the taste is, er, interresting. For me much more of a novelty than tasty food.
Here we go:
2 Beaver tails
1 / 2 cup wine vinegar
Salt and pepper
2 teaspoons baking soda (NaHCO3)
1 / 4 cup flour
Butter
1 glass of dry sherry
1 teaspoon Colemans mustard powder
1 teaspoon sugar
1 dash Worcestershire sauce
Flay the beaver tails, cut off fat and wash them in salty water. Put the tails in a mixture of vater, vinegar and salt. Store in fridge overnight.
Rinse the tails in cold water, put them in a casserole and cover them with a mixture of water and baking soda. Heat up, and let them simmer for 10 minutes. Dry off the tails, and sprinkle them with wheat flour. Fry them in a buttered pan until tender, low heat.
Mix the sherry with mustard, sugar and worchestershire sauce. pour the mixture over the tails and cook for another ten minutes.
