Bolognese Tagliatelle

1 . Stage

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.

2 . Stage

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.

3 . Stage

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.

4 . Stage

Pour beef stock and heavy cream into the pot and reduce heat to lowest setting. Simmer, partially covered and stirring occasionally, for at least 2 hours.

5 . Stage

Meanwhile, fill a large pot with lightly salted water and bring to a rolling boil. Cook tagliatelle at a boil until tender yet firm to the bite, about 8 minutes. Reserve 1 cup pasta water and drain well.

6 . Stage

Stir pasta into Bolognese sauce and mix well, adding a little reserved pasta water if needed to develop a satiny coating. Top with grated Parmesan cheese.
