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 ↓
Tomato Sauce
Ingredients
Directions
Simmer the base
Combine tomatoes, parsley, water, butter, garlic cloves, chopped onion, and allspice berries in a pot and cook for 20 minutes.
Brown and thicken
In a separate pan, brown the onion in butter.
Add flour and seasonings to the browned onion.
Gradually stir in the tomatoes.
Finish
Cook until there is no taste of raw starch, then strain the sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Its starch swells when cooked, thickening the sauce and giving it body.
- Tomatoes
- Provide the main liquid, acidity and fruity flavor of the sauce.
- Butter
- Adds fat for richness and carries flavor while the onion browns.
- Chopped onion
- Browning in butter builds sweetness and savory aroma into the sauce.
The step that matters
Cook until there is no taste of raw starch. Flour starch must be heated long enough to swell and thicken the sauce fully. Undercooked flour leaves a raw, pasty taste, so keep simmering until it is gone before straining.

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