Why it works: Veal and beef are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 3,784 recipes. Both carry 2,6-nonadienal, which smells cucumber, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Provides the gelatinous meat and skin that give the soup its body and texture.
- Egg yolks
- Add richness and help bind and thicken the soup.
- Butter
- Carries the shallot flavour and adds richness during the initial frying.
- Flour
- Thickens the gravy so it coats the broth and gives the soup body.
- Madeira wine
- Adds sweetness and depth of flavour as it simmers into the soup.
- Lemon juice
- Adds acidity that brightens the rich, heavy broth.
The step that matters
Simmer until the meat is tender. Calf's head needs a long, gentle simmer so its connective tissue breaks down into gelatin. Rushing or boiling hard leaves the meat tough and the broth thin.
Swap the parsley
How well each one fits the dish's main ingredients (egg, ham, veal, beef, butter, flour, madeira wine):

Fit is the average pairing score against egg, ham, veal, beef, butter, flour, madeira wine. Candidates are from the same food group and used in at least 100 recipes.
