Why it works: Clove and cinnamon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,189 recipes. Both carry ethyl cinnamate, which smells sweet, balsamic. The science ↓

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
