Why it works: Clove and allspice match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 7,874 recipes mention both. Both carry estragole, which smells anise, licorice. 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, acidity and sweet flavour of the soup as they break down.
- Onion
- Adds savoury sweetness and aromatic depth as it softens during slow cooking.
The step that matters
Cook slowly until the tomatoes are quite soft. Slow, gentle heat softens the tomato cell walls and draws out flavour without scorching the bottom of the pan. Rushing with high heat can burn the solids and leave a harsh, uneven taste.

Fit is the average pairing score against tomato, clove, allspice. 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).
