Heat a large frying pan on medium and once hot, add 1 tbsp unsalted butter.
Once the butter has melted, add 100 g yellow onion(s), 25 g celery, 30 g carrot(s) and 1 clove garlic to the pan and fry until the onion is soft and translucent.
Next, push the vegetables to the edges and add 150 g ground meat to middle of the pan. Fry until browned and mix everything together.
Once the meat has browned, add 1 tbsp red wine, 2 tbsp tomato ketchup, 1 tbsp Worcestershire sauce and 1 pinch ground black pepper. Mix thoroughly.
Add 400 g canned tomato along with 1 tsp sugar, ½ tsp oregano and 1 bay leaf. Mix well.
Lower the heat to a simmer and cook until reduced by half.
While it's simmering, bring 2500 ml water to a boil and add 2 ½ tsp salt. Once the water is boiling, add 240 g dry spaghetti and cook for the time stated on the packaging. (Reduce by 1-2 minutes for el dente.)
Once the meat sauce has reached your desired thickness, remove the bay leaf and add 1 pinch nutmeg powder and 1 pinch cinnamon. Mix well.
Drain the spaghetti and divide onto serving plates. Pour an equal amount of meat sauce on top of each portion of spaghetti. Sprinkle with 1 tsp grated parmesan cheese and 1 tsp fresh parsley (optional).
Enjoy!
