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

What each ingredient does

Tomatoes: Provide the bulk of the sauce, along with their juice, which gives body and liquid for simmering.
Tomato paste: Concentrates tomato flavor and adds body and deeper color to the sauce.
Garlic: Adds pungent aroma that mellows and sweetens during gentle sautéing and simmering.
Red onion: Adds savory sweetness and aromatic base flavor as it softens in the fat.
Olive oil: Carries fat-soluble aroma compounds from the aromatics and helps distribute flavor through the sauce.
Sugar: Balances the acidity of the tomatoes, rounding out the sauce's flavor.

The step that matters

Season in small additions after the paste goes in. Tomatoes vary in acidity and salt concentrates as the sauce reduces, so adding salt and sugar gradually and tasting between additions prevents an over-salted or unbalanced sauce.

Fit is the average pairing score against cream, butter, olive, garlic, onion, oregano, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
