Why it works: Tomato and garlic are a kitchen classic. They rank in the top 2% of all ingredient pairs, and 14,075 recipes mention both. Both carry furaneol, which smells caramel, strawberry. The science ↓

Directions
Make the sauce

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beefsteak
- Browns in the hot skillet and becomes tender during the long slow simmer.
- Tomato paste
- Adds concentrated tomato flavor and body to the sauce as it cooks down.
- Garlic
- Contributes pungent aroma that mellows and sweetens during slow cooking.
- Spaghetti
- Forms the base layers that hold the meat sauce and cheese.
- Mushrooms
- Add earthy flavor and a soft, moist texture when added at the end.
The step that matters
Cover and reduce heat to cook slowly for 3 to 4 hours. Low, covered heat over a long time lets the tough beef break down and become tender while the sauce thickens. Too high a heat can scorch the bottom of the pan and toughen the meat.

Fit is the average pairing score against tomato, mushroom, pepper, 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).
