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.
