1. Clean: Skin and clean the muskrat, carefully removing all the fat, scent glands, and the white tissue located inside each leg.

2. Brine: Soak the muskrat overnight, covered completely, in a weak brine solution made of 1 tablespoon of salt to 5 cups of water.

3. Prep: The next day, drain the meat, disjoint it, and cut it into serving pieces.

4. Coat: Place the flour, 1 1/2 teaspoons of salt, and the paprika into a paper bag. Add the muskrat pieces and shake vigorously until each piece is completely and evenly coated.

5. Melt: Melt the lard in a heavy frying pan or cast-iron skillet over medium heat until it is hot and shimmering.

6. Sear: Add the floured muskrat pieces to the pan and sauté slowly until they are deeply browned on all sides.

7. Layer: Once the meat is beautifully browned, cover it completely with the sliced onions. Sprinkle with salt and pepper to taste, then pour the sour cream evenly over the top.

8. Simmer: Cover the frying pan tightly with its lid, turn the heat down to low, and let it simmer gently for 1 hour until the meat is tender and the sauce is rich.
