Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 29,058 recipes mention both. Both carry furaneol, which smells caramel, strawberry. The science ↓
Tomato Sauce for Meat and Spaghetti
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the sauce
In a pot, combine tomatoes, onions, garlic, green peppers, bay leaves, and salt.
Boil for about 1 hour, then strain the mixture.
Combine and serve
Cook any leftover meat in gravy until tender.
Mix the strained sauce with the cooked meat, olive oil, and Worcestershire sauce.
Pour over boiled spaghetti and top with grated cheese.
Bake in the oven at 350°F (175°C) for 10 to 15 minutes and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Form the main body of the sauce and provide acidity and moisture as they break down.
- Onions
- Add sweetness and savory depth as they soften during the long simmer.
- Garlic
- Adds aromatic pungency that mellows and sweetens with cooking.
- Green peppers
- Contribute a fresh, slightly bitter vegetable flavor and body to the sauce.
- Olive oil
- Adds fat that carries flavor and gives the sauce a richer mouthfeel.
The step that matters
Boil for about 1 hour, then strain the mixture. A long simmer is needed to break down the tomatoes and vegetables and concentrate the flavor. Stopping early leaves a thin, raw-tasting sauce, while straining removes solids so the sauce is smooth.

Fit is the average pairing score against tomato, onion, garlic, pepper, olive, sauce, cheese. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
