Why it works: Clove and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 17,451 recipes. Both carry ethyl octanoate, which smells fruity, wine. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Canned tomatoes
- Form the sauce base and provide the main body and acidity.
- Butter
- Carries the flour and adds richness to the sauce.
- Flour
- Thickens the sauce as it cooks with the butter and tomatoes.
The step that matters
Stirring the butter and flour mixture into the tomatoes. Flour clumps if added without first cooking it in fat, so the roux must be stirred until smooth before it meets the hot tomatoes. Cooking the mixture for a few minutes afterward lets the flour swell fully and thicken the sauce without a raw starchy taste.
Swap the tomato
How well each one fits the dish's main ingredients (butter, flour, clove, onion, pepper):
- Leekfits better
- Chivefits better
- Shallotfits better
- Tomatothe original
Fit is the average pairing score against butter, flour, clove, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
