Why it works: Celery and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Mock Turtle Soup
Ingredients
Directions
Prepare the stock
Place the cleaned calf's head in a soup pot.
Add the soaked pickled pork, sweet herbs, onions, celery, truffles or morels, mace, and pepper.
Fill the pot with water, leaving some space at the top, and boil slowly until the meat is tender.
Remove the meat, cut it into square pieces, and break the bones, returning them to the pot.
Let the soup simmer for 4 to 5 hours, then cool it quickly and remove the fat.
Finish and serve
Strain the soup and thicken it with flour and butter.
Add Harvey's sauce, sherry or Madeira, and lemon juice.
Stir in the meat from the head and pork, and add egg balls or force-meat if desired.
Warm the soup and serve.

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 body and rich flavour of the soup stock.
- Flour
- Thickens the strained soup together with the butter into a smooth body.
- Butter
- Enriches the thickened soup and adds richness with the flour.
- Sherry or madeira
- Adds acidity and aromatic depth to the finished soup.
- Pickled pork
- Adds savoury, salty depth to the stock.
- Lemon juice
- Adds acidity that brightens the rich, heavy broth.
The step that matters
Cooling and removing the fat before thickening. Rapid cooling lets fat rise and set on top so it can be removed cleanly. Leftover fat would make the finished soup greasy and heavy.
Swap the mace
How well each one fits the dish's main ingredients (pork, onion, celery, truffle, pepper, sauce, sherry):
- Thymefits better
- Parsleyfits better
- Garlicfits better
- Macethe original
Fit is the average pairing score against pork, onion, celery, truffle, pepper, sauce, sherry. Candidates are from the same food group and used in at least 100 recipes.
