Legend has it that during the depression, the Bishop of Detroit declared muskrats to be fish (since they live in the water), so they could be eaten by Catholics on Fridays.
The recipe book I have has a recipe for muskrats for a crowd, that (for 20 rats) uses the above ingredients (but quantities unspecified, except it only uses 1/4 lb oleo), plus chopped green and red peppers, garlic salt, 5 bouillon cubes, and 3 bay leaves. Around Detroit, muskrats are cooked with cabbage and potatoes, and some folks at home roast them with apples and onions.
