Finnish Meatballs

1 pound lean ground beef
1 cup plain bread crumbs
1 yellow onion, minced
1 egg
1/2 cup whipping cream
2 teaspoons salt
1 teaspoon ground allspice (I didn't have allspice so I used French Onion Dip Mix instead)
1/4 cup butter

2 tablespoons all-purpose flour
2 cups milk
1/2 cup whipping cream
salt and pepper to taste

Mix the ground beef, bread crumbs, onion, egg, cream, salt, and allspice in a bowl with your hands until evenly mixed. Roll the mixture into golf ball-sized spheres.
Melt the butter in a large skillet over medium heat. Cook about half the meatballs in the melted butter until evenly browned on all sides, 5 to 7 minutes; remove to a plate and repeat with the remaining meatballs, keeping the liquid in the skillet when finished.
Sift the flour into the skillet drippings; cook the flour in the skillet drippings until brown, 2 to 3 minutes. Slowly stream the milk into the skillet while whisking vigorously; pour the cream into the mixture and stir until smooth. Add salt and pepper. If you aren't good at making gravy and end up with some lumps you can pour the gravy through a strainer. Return all the meatballs to the skillet; stir to coat with the gravy. Bring the mixture to a simmer and cook until the meatballs are cooked through, 15 to 20 minutes.
