Why it works: Sugar and cinnamon are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 30,779 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes (in the method)
- Form the bulk of the sauce and supply moisture that cooks down into a thick texture.
- Sugar
- Adds sweetness and helps balance the acidity of the vinegar.
- Vinegar (in the method)
- Provides acidity that sharpens the flavor and helps preserve the sauce.
The step that matters
Cook until thick as ketchup, but do not strain. The sauce thickens only as its water evaporates during long simmering. Stopping too early leaves it thin, while the chopped vegetables must stay unstrained so the sauce keeps its body and texture.
