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

What each ingredient does

Tomatoes
Provide the main body and bright acidity, and break down into the sauce's thickness as water evaporates.
Butter
Adds fat that carries flavour and gives the finished sauce a smooth, rounded mouthfeel.
Large onions
Contribute savoury aroma and some sweetness as their sugars develop during cooking.

The step that matters

Stir continuously until the sauce is thick. As water evaporates and the tomatoes break down, the sauce thickens. Sugars from the onions and tomatoes can scorch quickly on the hot base of the pan, so constant stirring keeps the sauce from catching and burning.
