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

What each ingredient does

Butter
Adds fat and rich flavor as the base for sautéing the vegetables and ham.
Ripe tomatoes
Provide the main body, acidity and flavor of the sauce as they cook down.
Flour
Thickens the sauce to the desired consistency when diluted in cold broth.
Onions
Add sweetness and savory depth once browned in the butter.
Lean raw ham
Contributes savory, meaty flavor to the sauce during the initial browning.

The step that matters

Adding the flour mixture. Flour must be diluted in cold broth before it goes into the hot sauce, because dry flour added directly clumps. Stirring until it boils then cooking gently lets the starch swell fully and thicken smoothly.

  4. Onionthe original

Fit is the average pairing score against butter, carrot, ham, tomato, parsley, thyme, 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).
