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 fresh tomato flavor, breaking down into the chutney's body as it simmers.
Plums: Add tartness and body, helping the chutney thicken as the fruit breaks down while simmering.
Brown sugar: Adds sweetness and helps balance the vinegar's acidity and the heat of the chile.
White wine vinegar or cider vinegar: Brings acidity that sharpens the flavor and helps preserve the chutney.
Curry powder: Supplies the warm, aromatic spice blend that defines the chutney's flavor.

The step that matters

Simmer until slightly thickened. Fruit and sugar thicken as water evaporates and pectin releases from the fruit. Stop too early and the chutney stays runny; cook too long and it turns stiff and sticky as it cools.
