Bolognese Tagliatelle

Cook pancetta in a pan over medium heat until it has released its fat and is crisp, 7 to 8 minutes. Add carrots, celery, and onions; cook until vegetables soften and onions are translucent, 7 to 8 minutes. Set aside.

Heat olive oil in a 4-quart pot over medium heat. Break ground beef and pork into small chunks and add them to the pot; cook, stirring lightly, until browned, 7 to 8 minutes.

Stir pancetta-vegetable mixture into ground meat. Add wine. Reduce heat to medium-low and stir, breaking up meat until finely ground, until wine has evaporated and the pot is almost dry, 13 to 15 minutes. Add tomatoes, nutmeg, salt, and red pepper. Use the back of a spoon to break up tomatoes and continue to break down meat mixture into tiny bits, about 5 minutes.
