Add the garlic, celery and carrots and cook for further 5 minutes or until the carrots and celery have softened.
Add the minced beef and pork to the pan, breaking up the meat with a wooden spoon and stirring until all the meat has browned.
Season with sea salt and black pepper
Add the wine and cook until it has mostly reduced.
Add the milk, and cook until it has mostly reduced.
Add the tinned tomatoes, bay leaves and thyme.
Cook for on a low heat until the meat has become very tender (about 2 hours) gently stirring every 20 minutes. Do not let it boil - the heat should be just low enough to allow very gentle bubbles to rise to the surface.
Serve with spaghetti or your favourite pasta, and plenty of freshly grated parmesan cheese.
