Why it works: Celery and carrot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,173 recipes. Both carry myristicin, which smells spice, warm. The science ↓
Spaghetti with Bolognese Meat Sauce
Serves 4Ingredients
Directions
Make the sauce base
Mix the coarsely chopped onion, carrot, celery, and fennel (optional) together and finely chop them into a battuto.
Cut the ham or bacon into little cubes and sauté in a heavy saucepan.
Add the butter and allow it to melt, then add the battuto.
Cook, stirring occasionally, until the mixture is very lightly browned; then transfer it to a heavy pot.
Heat the olive oil in the skillet where the battuto was browned; when the oil is hot, add the beef and stir to break up lumps, cooking until well browned.
Add the browned beef to the battuto in the pot.
Add the wine to the skillet with the beef, stir on high heat, scraping any brown bits from the pan.
Add the tomato paste and stock, stir until well mixed, then pour this mixture into the pot.
Drain and coarsely chop the plum tomatoes, and add them to the pot.
Simmer the sauce
Add the bay leaf and lemon rind; bring the pot to a boil, then reduce to a gentle simmer with barely breaking bubbles.
Simmer, stirring occasionally, for an hour or more until thickened.
Add pepper and salt to taste.
Cook and serve
Bring a gallon (4 litres) of water to a full boil over high heat in a large pot.
Add the pasta, give it a brisk stir to keep it from clumping, and cook for about 10–12 minutes or until al dente.
Drain the pasta well and serve immediately.
Remove the bay leaf and lemon rind, then spoon the Bolognese sauce over the pasta and garnish with grated Parmesan cheese.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main meaty body and savory flavor once browned and simmered into the sauce.
- Tomato paste
- Concentrates tomato flavor and adds color and depth to the sauce.
- Red wine
- Adds acidity and aromatic depth, and its browned bits enrich the sauce.
- Beef stock
- Supplies liquid that carries flavor and lets the sauce simmer into a thick consistency.
- Butter
- Adds richness and fat that carries flavor through the battuto.
- Plum tomato
- Adds moisture, acidity, and fresh tomato body to the sauce.
The step that matters
Browning the beef. Searing the beef in a hot pan until well browned, and breaking up lumps, creates Maillard flavor. Crowding the pan or stirring too early makes the meat steam and turn grey, leaving the sauce flat.
Swap the fennel
How well each one fits the dish's main ingredients (ham, beef, olive, onion, celery, carrot, butter):
- Parsleyfits better
