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 ↓
Chutney
Ingredients
Directions
Make the chutney
Cook the apples, onions, and garlic in the vinegar until soft.
Rub the mixture through a sieve.
Steep the mustard seed in vinegar, then add it to the apple mixture.
Stir in the brown sugar, coarse sea salt, ginger, and chopped raisins.
Beat with a wooden spoon until smooth and blended.
Bottle and seal
When cold, transfer to wide-mouthed bottles and seal.
Pour a little olive oil over the top to prevent air exposure.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cider vinegar
- Provides the acidity that gives the chutney its tang and helps preserve it.
- Sour apples
- Supply pectin and tartness, giving body and a sharp flavour to the chutney.
- Onions
- Add savoury depth and bulk, softening into the mixture as it cooks.
- Mustard seed
- Adds a pungent, slightly bitter bite and a noticeable texture when steeped in vinegar.
- Brown sugar
- Adds sweetness and a molasses note that balances the sharp vinegar and apples.
- Raisins
- Add chewy texture and concentrated sweetness.
The step that matters
Rub the mixture through a sieve. Cooked apples and onions must be fully softened before sieving, or the purée stays lumpy and uneven. Pushing through a sieve removes fibrous pieces and skins, giving a smooth, blended texture.
Swap the apple
