Preheat oven to 375 F.
In a large mixing bowl, combine the ground beef, ground pork, eggs, Panko breadcrumbs, minced onion, ground allspice and ground nutmeg and salt and pepper. Using an ice cream scoop, form meatballs and place them in a single layer into a baking dish. Bake in the preheated oven for 25 to 30 minutes, or until cooked through. Cooking time may vary depending on size of meatballs.
While the meatballs are baking, make the cream sauce. Melt the butter in a large skillet, then stir in the flour to make a thick paste. Quickly stir in the beef broth and whisk vigorously to keep flour from clumping. Once the beef sauce begins to thicken, stir in the sour cream and red raspberry preserves. Pour the sauce over the meatballs once they finish baking.
Cook the pasta, as directed.
Prepare the salad.
