Why it works: Clove and cinnamon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,189 recipes. Both carry ethyl cinnamate, which smells sweet, balsamic. The science ↓
Tomato Chutney
Ingredients
Directions
Prepare the tomatoes
Sprinkle salt over each layer of sliced tomatoes and let them drain for 24 hours.
Make the chutney
In an enamelled preserving pan, combine the drained tomatoes and vinegar to cover them completely.
Add the sugar, onions, chillies, cloves, and cinnamon stick.
Stew the mixture gently in the uncovered pan until the tomatoes are tender, about 20-30 minutes.
Jar and seal
Pour the hot chutney into jars holding about 2 lbs each and seal immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Form the bulk of the chutney and break down to a thick, spreadable texture when stewed.
- Vinegar
- Adds acidity that sharpens the flavour and helps preserve the chutney.
- Sugar
- Adds sweetness that balances the acidity and helps thicken the chutney as it reduces.
- Onions
- Add savoury body and sweetness that softens during slow stewing.
The step that matters
Stew gently in an uncovered pan. Gentle heat in an open pan lets excess moisture evaporate so the chutney thickens. Boiling hard can scorch the sugar and break the tomatoes unevenly, while covering would trap steam and leave it watery.
Swap the onion
How well each one fits the dish's main ingredients (tomato, vinegar, sugar, clove, cinnamon):
- Capsicumfits better
- Cucumberfits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against tomato, vinegar, sugar, clove, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
