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 acidity that form the body of the sauce.
Sugar
Adds sweetness and helps balance the acidity of the tomatoes and vinegar.
Vinegar
Adds acidity, which brightens the flavour and helps preserve the sauce.
Onions
Contribute savoury depth and aroma as they soften during the long simmer.
Green peppers
Add a grassy, vegetal flavour and some body as they cook down.

The step that matters

Simmer for half a day, stirring occasionally. A long, gentle simmer lets water evaporate and the sauce thicken and deepen in flavour. Occasional stirring prevents scorching on the bottom of the pot, since sugar-rich sauces burn easily.

Swap the onion
