Soak the bread in the milk for a few minutes, and remove excess milk
by squeezing the bread with your hands. Break up the bread into small pieces and add to a mixing bowl with the ground pork, ground beef, raisins
, pine nuts, parsley, basil
, Parmigiano cheese, and salt and pepper.
Add the eggs, and mix until the ingredients are evenly distributed. With your hands, shape the meatballs into the size of golf balls.
In a large pot, heat the extra-virgin olive oil
and cook the onion until translucent. Add the wine
, and tomato puree, and bring it to a boil. Add the uncooked meatballs to the pot and let cook on medium heat until cooked through, about 30 minutes.
