Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour apples
- Provide tartness and pectin that helps the chutney thicken as it cooks.
- Dark sugar
- Adds sweetness and, as it reduces, deepens colour and gives a rich, caramel-like flavour.
- Vinegar
- Adds acidity that balances the sweetness and helps preserve the chutney.
- Onions
- Contribute body and savoury depth as they soften during the long boil.
- Ground rice
- Thickens the mixture as its starch gelatinises during cooking.
The step that matters
Boil together for 8 hours, stirring occasionally. A long, gentle boil lets water evaporate so the chutney thickens and darkens. Occasional stirring prevents the sugars and starches from scorching on the bottom of the pot.
Swap the apple
How well each one fits the dish's main ingredients (sugar, onion, garlic, rice, tomato, bread, pepper):
- Avocadofits better
- Limefits better
- Cherryfits better
- Applethe original
Fit is the average pairing score against sugar, onion, garlic, rice, tomato, bread, pepper. Candidates are from the same food group and used in at least 100 recipes.
