In a large bowl, combine ground beef, ground pork, eggs, onion, raw ground potatoes, dry bread crumbs, salt, pepper, brown sugar, ginger, nutmeg, cloves, allspice, and cinnamon.

Mix all ingredients thoroughly until well combined.

Shape the mixture into one-inch meatballs.

Roll each meatball in flour to coat.

Place the floured meatballs in a baking pan.

Pour milk over the meatballs, ensuring it covers the bottom of the pan.

Bake in a preheated oven at 350°F (175°C) for 30 minutes.

Turn the meatballs over.

Bake for an additional 30 minutes, or until fully cooked and browned.
