Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ingredients
Directions
Make the stock
Break the bones of the calf's head and place them in a saucepan with beef and veal bones.
Season the bones with fried onions, herbs, mace, and pepper.
Boil the ox palates until tender, then cut them into small pieces.
Add the cow heel pieces for extra flavor.
Make the gravy
In a separate pan, brown the butter, flour, and onion.
Pour the gravy into the browned mixture and stir well.
Combine and finish
Add the meats and stew together.
Stir in the sherry, anchovy, walnut catsup, mushroom catsup, and chopped herbs.
Squeeze the lemon juice into a tureen.
Pour the prepared soup over the lemon juice.

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):
- Parsleyfits better
- Thymefits better
- Marjoramfits better
- 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.
