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 liquid that form the bbulk of the sauce.
Onions
Add sweetness and aromatic depth as they soften during long cooking.
Vinegar
Adds acidity that sharpens flavor and helps keep the sauce preserved.
Sugar
Adds sweetness that balances the acidity of the vinegar.
Mustard seed
Contributes pungent, slightly bitter flavor that deepens during cooking.

The step that matters

Cook slowly for 2 to 3 hours. Low, gradual heat lets water evaporate so the sauce thickens without scorching on the bottom. Stirring keeps sugars from burning and lets the flavors meld.

Swap the onion
