Add the ground beef to a large skillet over medium-high heat and cook until no pink remains. Set aside.

Add the bacon to a second skillet (stainless steel if possible) over medium-high heat and fully cook. Remove the bacon from the skillet, leaving the grease behind.

Carefully add the vinegar to deglaze the pan (remove any stuck bits on the bottom) before adding the onions, carrots, and garlic. Stirring often, cook until the onions and carrots soften, about 5-7 minutes.

Add the tomatoes, cooked bacon, fish sauce, and spices to the onion and carrot mixture. Cook for 2-3 minutes, stirring continuously, before reducing the heat to medium-low.

Add the bay leaves and stir well before adding the beef. Continue cooking over medium-low while the pasta cooks, about 10-15 minutes. (Remove the bay leaves before adding the cooked pasta.)

Cook the pasta in salted water. Add 1/2 cup of the pasta water to the bolognese and stir well before adding the cooked pasta. Toss everything together and remove from the heat.
