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

What each ingredient does

Tripe
Forms the main body of the dish and becomes tender after simmering in the sauce.
Canned tomatoes
Provide the liquid base, acidity and fresh tomato flavour of the sauce.
Flour
Thickens the tomato liquid into a smoother, more cohesive sauce when cooked with butter.
Butter
Adds richness and helps make the flour thickening smooth and glossy.
Spanish onion
Adds savoury sweetness and aroma to the tomato sauce.

The step that matters

Thicken the mixture with flour and butter. Flour must be cooked into the butter and hot liquid to prevent lumps and a raw starchy taste. Stirring well while the sauce is at a simmer lets the starch swell evenly and thicken the sauce smoothly.

Swap the onion
