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
- Tomatoes
- Provide the main body, moisture, and tart flavor of the sauce.
- Butter
- Adds richness and fat, carrying flavor through the sauce.
- Flour
- Thickens the sauce as it cooks with the butter into a smooth base.
The step that matters
Stirring the butter and flour until smooth and brown. Flour must be fully mixed into the melted butter and cooked so the starch swells evenly. Lumps stay if it is added too fast, and cooking it briefly removes raw floury taste and thickens the sauce.
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.
