Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Tomatoes
Form the main body of the sauce and supply its acidity and fresh flavor.
Onion
Adds savory sweetness and a flavor base as it softens in the tomatoes.
Cloves
Contribute warm, aromatic spice notes to the sauce.
Butter
Adds fat for richness and a smoother mouthfeel in the finished sauce.
Flour
Thickens the sauce as its starch swells in the hot liquid.

The step that matters

Stir the butter-flour mixture into the tomato mixture and cook. Flour thickens only when its starch is evenly dispersed and heated. Adding it unevenly can form lumps, and not cooking it long enough leaves a raw, floury taste. Keep stirring while it cooks.

Swap the tomato
