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

What each ingredient does

Tongue: Forms the main body of the dish, and its meat is cooked gently by boiling.
Flour: Thickens the broth into a sauce by swelling with heat and binding the liquid.
Tomatoes: Provide acidity and body to the sauce, along with their characteristic flavour.
Broth: Supplies the liquid base of the sauce and adds savoury flavour.
Onion: Adds savoury depth and aroma as it softens in the sauce.

Fit is the average pairing score against flour, parsley, carrot, pepper, tomato. 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).
