Why it works: Cinnamon and clove 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
- Form the bulk of the sauce and supply moisture and tartness that cooks down into a thick base.
- Apples
- Add natural pectin that helps the sauce thicken and gives it body as it cooks.
- Brown sugar
- Adds sweetness and helps balance the tomato's acidity while thickening the sauce.
- Cinnamon
- Adds warm, sweet aroma that gives the sauce its characteristic flavor.
- Allspice
- Adds warm, peppery aroma that deepens the spiced flavor of the sauce.
- Cloves
- Adds strong, pungent aroma that rounds out the spiced flavor of the sauce.
The step that matters
Add the spices one hour before finishing. Volatile aromatic compounds in cinnamon, allspice, and cloves fade during long cooking. Adding them late keeps more of their fragrance in the finished sauce.
