Why it works: Thyme and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 9,057 recipes mention both. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Knuckle of Veal Soup
Ingredients
Directions
Prepare
Break the bones of the knuckle and wash it.
Place skewers in the stew pan to prevent sticking.
Simmer
Cover the knuckle with water and add celery, thyme, onions, carrot, turnip, parsley, and peppercorns.
Simmer until the knuckle is tender.
Finish
Strain the soup and cut the meat into bite-sized pieces.
Season with white pepper, mace, and add rice flour to thicken if desired.

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).
