Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main bulk, moisture and fresh tomato flavour of the chutney.
- Sugar
- Adds sweetness and helps balance the sharpness of the vinegar.
- Vinegar
- Adds acidity that sharpens the flavour and helps preserve the chutney.
- Onions
- Add aromatic pungency that mellows and sweetens during long simmering.
- Raisins
- Add concentrated sweetness and chewy texture as the chutney thickens.
The step that matters
Simmer slowly for 2 hours. Slow simmering lets water evaporate gradually so the mixture thickens and the flavours blend. Too fast a boil can scorch the sugar and fruit on the bottom of the kettle and leave the chutney dark and bitter.
Swap the raisin
How well each one fits the dish's main ingredients (tomato, pepper, onion, sugar, vinegar, ginger):
- Limefits better
- Mangofits better
- Cherryfits better
- Raisinthe original
