Why it works: Cheese and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 7,962 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Spaghetti with Tomato Sauce
Ingredients
Directions
Cook the spaghetti
Place a handful of spaghetti in a kettle of boiling salted water.
As it softens, bend and coil it round in the kettle.
Cover and cook for 15 to 20 minutes, or until tender.
Drain in a colander.
Make the sauce and serve
Return to the kettle with enough tomato sauce to make it moist.
Add ⅓ cup of grated cheese, 1 tablespoon of butter, and a dash of paprika.
Cook slowly until the sauce is mostly absorbed.

Sauce and butter barely smell alike, yet cooks put them together in 15,338 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spaghetti
- Forms the bulk of the dish and gives it its chewy, tender texture.
- Tomato sauce
- Adds moisture and acidity that coat the pasta as the sauce reduces.
- Grated cheese
- Adds salty, savory flavour and helps the sauce cling to the pasta.
- Butter
- Adds fat and richness, giving the sauce a smoother mouthfeel.
The step that matters
Cook slowly until the sauce is mostly absorbed. Gentle heat lets the sauce thicken and cling to the spaghetti without scorching the butter and cheese, which can turn grainy or burn on the bottom of the pan.
Swap the tomato
How well each one fits the dish's main ingredients (sauce, cheese, butter):
- Mustardfits better
- Tomatothe original
- Onionfits about as well
- Potatofits about as well
Fit is the average pairing score against sauce, cheese, butter. Candidates are from the same food group and used in at least 100 recipes.
