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 ↓
Italian Tomato Sauce
Ingredients
Directions
Make the tomato base
Simmer together the tomatoes, garlic, parsley, mixed herbs, allspice, and peppercorns for 20 minutes.
Make the sauce
In a separate pan, slowly brown the chopped onions in butter until very dark.

Simmer for an additional 10 minutes.
Stir in the salt and rub the sauce through a sieve.

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 sauce.
- Onions
- Brown slowly to add deep, sweet, savoury colour and flavour to the sauce.
- Butter
- Carries the browning of the onions and adds richness.
- Flour
- Mixed with the onions and stock to thicken the sauce.
- Rich stock
- Adds liquid and savoury depth, loosening the thickened onion mixture into a sauce.
The step that matters
Browning the onions until very dark. Onions cooked slowly in butter caramelise, developing deep sweet and savoury flavour. Stopping early leaves a flat, raw taste, while burning gives bitterness.
Flavor stand-ins for the onion

Fit is the average pairing score against tomato, clove, garlic, parsley, allspice, butter, flour. 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.
