Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Tomato Chutney
Ingredients
Directions
In a large pot, combine the tomatoes, vinegar, salt, onion, ground white pepper, and cayenne pepper.
Boil the mixture together, then press it through a sieve.
Add the sliced apples, stoned raisins, sugar, and lemon juice.
Boil until the raisins are tender.
Once cooled, transfer the chutney into small jars.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Form the bulk of the chutney and provide its main body and flavour.
- Vinegar
- Adds acidity that gives the chutney its sharp, tangy character.
- Sugar
- Adds sweetness that balances the vinegar and acidity.
- Apples
- Add body and pectin that help the chutney thicken as it cooks.
- Raisins
- Add chewy texture and concentrated sweetness as they soften in the boil.
The step that matters
Boil until the raisins are tender. The chutney needs enough cooking for the raisins and apples to soften fully and the mixture to thicken. Stopping too early leaves a thin, uneven texture and firm pieces of fruit.
Swap the white pepper
How well each one fits the dish's main ingredients (tomato, vinegar, onion, pepper, apple, raisin, sugar):
- Cinnamonfits better
- Clovefits better
- Gingerfits better
