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 meat and gelatinous body that give the soup its rich, mock-turtle character.
Flour
Browned with butter and onion to thicken the gravy and give it body.
Butter
Browned with flour and onion to add nutty flavor and fat for the gravy base.
Sherry
Adds acidity and aromatic depth to the finished soup.
Lemon juice
Adds bright acidity that lifts the rich, meaty soup.
Ox palates
Contribute tender, gelatinous meat pieces that give the soup its texture.

The step that matters

Browning the butter, flour, and onion. Cooking the flour in butter until well browned builds the roux's color and nutty flavor, and it thickens the gravy only if the flour is cooked enough to lose its raw taste. Stirring constantly prevents scorching, which would make the gravy bitter.

Swap the mace

How well each one fits the dish's main ingredients (lemon, meat, beef, veal, onion, pepper, butter):

  1. Parsleyfits better
  2. Thymefits better
  3. Marjoramfits better
  4. Macethe original

Fit is the average pairing score against lemon, meat, beef, veal, onion, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
