Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Moist sugar
- Adds sweetness and body, and helps preserve the chutney as it thickens.
- Vinegar
- Provides acidity that balances the sweetness and helps preserve the chutney.
- Apples
- Release pectin as they simmer, helping the chutney thicken to a spoonable texture.
- Onions
- Soften during simmering, adding savoury depth and bulk to the chutney.
- Tomatoes
- Break down during simmering, contributing moisture and body to the chutney.
The step that matters
Cool before bottling. Filling jars while the chutney is still hot traps steam, which can cause condensation and spoilage. Letting it cool first helps the seal stay reliable.
Swap the raisin
How well each one fits the dish's main ingredients (sugar, ginger, apple, vinegar, onion, mustard, tomato):
- Cherryfits better
- Plumfits better
- Mangofits better
- Raisinthe original
Fit is the average pairing score against sugar, ginger, apple, vinegar, onion, mustard, tomato. Candidates are from the same food group and used in at least 100 recipes.
