1/4 cup extra-virgin olive oil 1 onion, finely chopped 1 stalk celery, finely chopped 1 large carrot, finely chopped 2 tbsp unsalted butter 1/2 lb. ground beef 1/2 lb. ground pork 1 cup dry white wine 1 cup milk 3 cups passata ( puréed tomatoes- Contadino) Salt to taste

1. Heat olive oil in large pan over medium heat. When it starts to shimmer, add onion, celery and carrots. Let cook until soft and somewhat translucent, so flavors come together, and become sweet and intense.
2. Add butter and ground beef and pork. Increase heat to high.
3. Cook, stirring frequently so nothing sticks to bottom of pan, until moisture in meat has been released and meat is lightly browned.
4. Add wine, stir again to pick up any bits on bottom of pan, and cook until most liquid has evaporated.
5. Add milk and cook until milk has reduced by 3/4.
6. Stir in passata and salt. Reduce heat to low and let simmer, stirring occasionally, for a few hours to let flavors come together and intensify.
