Why it works: Allspice and clove 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 ↓

Make the sauce

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the base purée and body of the sauce, along with natural acidity.
- Brown sugar
- Adds sweetness and helps preserve the sauce while cooking down into a thick texture.
- Vinegar
- Adds acidity that sharpens flavour and helps preserve the sauce.
- Spanish onion
- Adds savoury depth and body to the sauce as it cooks down.
The step that matters
Pass the mixture through a fine sieve. Cooked tomatoes and onions contain fibrous solids that must be fully strained to give a smooth, pourable sauce; leftover pieces can make the texture grainy and affect how well the sauce keeps in the bottle.
Flavor stand-ins for the onion
How well each one fits the dish's main ingredients (vinegar, tomato, sugar, allspice, clove):
- Capsicumbetter flavor fit
- Mustardbetter flavor fit
- Cucumberbetter flavor fit
- Onionthe original
Fit is the average pairing score against vinegar, tomato, sugar, allspice, clove. 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).
