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 ↓

Ingredients
Directions
Cook all ingredients except butter and flour together until tomatoes are soft.

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 and flavour of the sauce once cooked and strained.
- Flour
- Thickens the sauce as it cooks with the butter and then boils.
- Butter
- Carries the flour and adds richness and a toasted flavour to the sauce.
The step that matters
Stir until it boils and is smooth. Flour thickens only once it is well dispersed and heated to a boil. Stirring while adding the strained mixture prevents lumps and lets the starch swell evenly into a smooth sauce.
Flavor stand-ins for the onion
How well each one fits the dish's main ingredients (tomato, parsley, sugar, pepper, clove, allspice, butter):

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