Why it works: Parsley and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓

Ingredients
Directions
Prepare
In a well-tinned stewpan, combine the veal, ham, beef, and any trimmings from game or poultry.
Moisten with broth and add the carrots, onions, parsley, thyme, and mushrooms.
Cook the base
Let the meat sweat without browning, pricking it to release juices.
Once the knuckle is cooked, skim the sauce and strain it through a fine sieve.
Thicken and finish
Boil the sauce until reduced, then add enough roux blanche or cream to achieve a thick consistency.
Skim the sauce again and boil while stirring, lifting it with a spoon to make it smooth.
Continue this process until the sauce cools.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal knuckle
- Provides rich gelatin and meaty flavour that give the finished sauce body.
- Beef
- Adds savoury depth to the broth that forms the base of the sauce.
- Ham
- Contributes salty, smoky flavour to the stock.
- White thickening (roux blanche)
- Thickens the sauce to a smooth, coating consistency through starch gelatinisation.
- Onions
- Add sweetness and aromatic depth as they slowly soften in the stock.
The step that matters
Skimming and stirring while thickening. Skimming removes fat and impurities that would make the sauce greasy or cloudy, and constant stirring prevents the starch from clumping, keeping the velouté smooth.
Swap the onion
How well each one fits the dish's main ingredients (veal, ham, beef, carrot, parsley, thyme, mushroom):
- Shallotfits better

- Turnipfits about as well
- Onionthe original
Fit is the average pairing score against veal, ham, beef, carrot, parsley, thyme, mushroom. Candidates are from the same food group and used in at least 100 recipes.
