Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Ripe tomatoes
Form the sauce's base, providing most of its body and liquid volume.
Onions
Add savory depth and body as they soften during the long cook.
Vinegar
Adds acidity that brightens the sauce and helps preserve it.
Sugar
Adds sweetness that balances the acidity of the tomatoes and vinegar.
Cinnamon
Contributes warm aroma and spice flavour to the sauce.

The step that matters

Stir gently over the fire for 1 hour. Sugar-rich tomato mixtures can scorch on the bottom of the pot if left unattended, giving a burnt taste. Gentle, frequent stirring over moderate heat spreads heat evenly and lets the sauce thicken without sticking.

Swap the onion

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