Add ground beef and pork, brown. Drain all fat. Add wine to meat and veggie mixture, cook on medium high heat until wine evaporates, then add a splash of olive oil, pureed tomatoes and whole garlic cloves (remove these before serving.) Cook this sauce just on a simmer for 2 hours. If sauce becomes too dry, add beef broth or tomato juice a little at a time, you want your sauce to remain thick. At the end of 2 hours on a slow simmer, add milk a little at a time, keeping sauce thick, and continue cooking on a slow simmer for 1 more hour.
