Why it works: Cinnamon and allspice match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 5,536 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Tomato Relish
Ingredients
Directions
Make the relish
Combine the chopped tomatoes, onions, and green peppers in a large pot.
Add salt, cinnamon, allspice (or cloves), sugar, and vinegar.
Simmer the mixture for at least 3 hours, stirring often to prevent burning.
Jar
Seal the hot relish in glass jars.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ripe tomatoes
- Form the bulk of the relish and provide its main body and moisture.
- Onions
- Add savory depth and aroma that builds as they cook down.
- Green peppers
- Contribute a fresh, slightly bitter vegetable note and extra texture.
- Sugar
- Adds sweetness that balances the acidity of the vinegar.
- Vinegar
- Adds acidity that brightens the relish and helps preserve it.
The step that matters
Simmer for at least 3 hours. Long, gentle simmering evaporates water and thickens the relish. Stirring often keeps sugars from scorching on the bottom of the pot.
Swap the onion
How well each one fits the dish's main ingredients (tomato, pepper, cinnamon, allspice, sugar, vinegar):
- Capsicumfits better
- Mustardfits better
- Cucumberfits better
- Onionthe original
Fit is the average pairing score against tomato, pepper, cinnamon, allspice, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
