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

What each ingredient does

Veal shin: Releases gelatin and savory flavor into the broth during long simmering.
Vermicelli: Adds starch and body to the soup as it cooks in the broth.

Fit is the average pairing score against veal, carrot, turnip. 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).
