Preparation
In a large pot, heat EVOO over medium-high heat, then add the pancetta and cook, stirring occasionally, until browned and the fat is rendered, 4-5 minutes. Remove from pan and reserve.
Add the sirloin and pork to the pot the pancetta was cooked in and brown well, about 10 minutes. Add the onion, carrots, celery, garlic and cook, stirring, until soft, 4-5 minutes.
Add salt, pepper, allspice, bay leaves and thyme, and cook, stirring, for 30 seconds. Add the reserved pancetta back into the pan and stir in the tomato paste. Cook 3-4 minutes to caramelize. Add in the wine and scrape up all the tasty nibbles that have stuck to the bottom of the pan. Cook until half of the liquid is evaporated, about 2 minutes.
