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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked tomatoes
- Provides the main body, acidity and flavour of the soup.
- Flour
- Thickens the soup as its starch cooks, giving it body.
- Butter
- Adds richness and fat, giving a smoother mouthfeel.
- Sugar
- Balances the acidity of the tomatoes with sweetness.
The step that matters
Pressing through the sieve. Pressing the simmered mixture through a sieve removes solids and fibre, giving the smooth texture a cream soup needs. Skipping or rushing this leaves the soup grainy.

- Onionthe original
Fit is the average pairing score against tomato, pepper, clove, sugar, flour, butter. 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.
