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

What each ingredient does

Veal knuckle
Provides bone, connective tissue and meat that release gelatin and flavour into the broth as it simmers.
Onions
Add sweetness and savoury depth to the broth as they cook down.
Celery
Adds aromatic, savoury flavour to the stock during simmering.
Rice flour
Thickens the soup slightly when added, if desired.

The step that matters

Simmer until the knuckle is tender. Gentle simmering lets collagen in the connective tissue slowly break down into gelatin, giving tender meat and a richer body. A hard boil can toughen the meat and cloud the broth.

Fit is the average pairing score against veal, celery, lemon, thyme, carrot, turnip, parsley. 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).
