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

What each ingredient does

Flour
Thickens the sauce as it heats with the liquid, giving it body.
Onion
Adds savory sweetness and aroma as it softens in the oil.
Vinegar
Adds acidity that gives the sauce its sharp flavor.
Tomato
Adds acidity, body and savory flavor to the base.

The step that matters

Add the flour and stir until well combined. Flour clumps if it hits hot liquid unevenly. Stirring it smoothly into the oil and vegetables first lets it coat the solids so the sauce thickens evenly when the liquid is added.
