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

What each ingredient does

Canned tomatoes
Form the sauce base and provide the main body and acidity.
Butter
Carries the flour and adds richness to the sauce.
Flour
Thickens the sauce as it cooks with the butter and tomatoes.

The step that matters

Stirring the butter and flour mixture into the tomatoes. Flour clumps if added without first cooking it in fat, so the roux must be stirred until smooth before it meets the hot tomatoes. Cooking the mixture for a few minutes afterward lets the flour swell fully and thicken the sauce without a raw starchy taste.
