Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the bulk and moisture that cook down into the chutney's body.
- Vinegar
- Adds sharp acidity and helps preserve the chutney.
- Sugar
- Adds sweetness that balances the acidity and helps preserve the chutney.
- Apples
- Add body and natural pectin, helping the chutney thicken as it cooks.
- Onions
- Add savoury bulk and mellow sweetness as they soften during cooking.
- Garlic
- Adds pungent aroma and savoury flavour that mellows with long cooking.
The step that matters
Boil for three hours. Long simmering evaporates water and concentrates the mixture, so it thickens and the sugar and vinegar work to preserve it. Cooking it too briefly leaves it watery and less stable.
Swap the apple
How well each one fits the dish's main ingredients (tomato, allspice, garlic, vinegar, pepper, sugar, onion):
- Limefits better
