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 moisture that cook down into the relish.
Onions
Add savoury flavour and body as they soften during the long simmer.
Red peppers
Add sweetness, colour, and a mild vegetal flavour.
White sugar
Adds sweetness and balances the sharpness of the vinegar.
Vinegar
Adds acidity that brightens flavour and helps preserve the relish.

The step that matters

Boil gently for 3 hours, stirring occasionally. A long, gentle simmer lets water evaporate so the relish thickens and its flavours concentrate. Stirring prevents the sugar and vegetables from sticking and scorching on the bottom of the pot.

Swap the onion

How well each one fits the dish's main ingredients (tomato, pepper, sugar, vinegar):
