Why it works: Onion and parsley are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 25,843 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Gravy, Veal, for White Sauce
Ingredients
Directions
Place the ham at the bottom of a saucepan with the veal pieces.
Cover with ½ cup of broth and boil quickly at first, then gently until the meat glazes.
Pierce the meat with a skewer and shake the pan frequently to prevent burning.
Once the glaze is lightly brown, gradually add 2 pints of broth.
Simmer gently for 2 hours.
For flavor, add an onion and parsley while simmering, if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal neck or knuckle
- Provides the meat and collagen that enrich the broth as it simmers.
- Lean ham
- Adds savory, salty depth and browns onto the bottom of the pan to flavor the sauce.
- Broth
- Forms the liquid base that becomes the sauce as it reduces and carries flavor.
The step that matters
Browning the glaze before adding broth. Meat must brown lightly in the pan's residue without burning; this builds deep flavor through browning reactions. Shaking the pan and piercing the meat prevent scorching, and adding the broth too early would stop the glaze from forming.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (ham, veal, parsley):
- Carrotfits better
- Shallotfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against ham, veal, parsley. Candidates are from the same food group and used in at least 100 recipes.
