Why it works: Pepper and clove match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and 17,451 recipes mention both. Both carry ethyl octanoate, which smells fruity, wine. The science ↓
Another Tomato Soup
Ingredients
Directions
Make the soup
Place the bones, onion, carrot, and tomatoes in a pot.
Add pepper and cloves, then boil for 2-3 hours.
Strain out the bones and tomato seeds, and skim off the fat.

Add sugar and let it boil for 10 minutes.
Serve
Place toasted bread squares in a tureen and pour the soup over them.

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, acidity and flavour of the soup.
- Arrowroot
- Thickens the soup into a smooth, glossy body without clouding it.
- Ground rice or flour
- Adds starch that thickens the soup and gives it body.
- Sugar
- Balances the acidity of the tomatoes with sweetness.
The step that matters
Stir in arrowroot and ground rice or flour before boiling. Starch must be dispersed in cold liquid first to avoid lumps; once heated, it swells and thickens the soup. Adding it to hot liquid directly causes clumping.</br>

- Onionthe original
Fit is the average pairing score against carrot, tomato, pepper, clove, arrowroot, rice, sugar. 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).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
