Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Codling and Haddock Soup
Ingredients
Directions
Make the forcemeat balls
Pound the codling meat in a mortar with the shrimps.
Add the chopped parsley and soaked roll, and pound until combined.
Form the mixture into balls using the egg, and season with mace and pepper.
Make the soup
Stew the codlings or haddocks in broth until cooked, then strain.
Remove the meat, pulp it through a sieve, and boil with parsley roots.
Thicken the soup and serve with the forcemeat balls.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codlings or haddocks
- Provides the flaky fish body that gives the soup and forcemeat their main substance.
- Egg
- Binds the pounded fish and shrimp mixture so it holds together as balls.
- Soaked roll crumb
- Adds softness and moisture to the forcemeat, keeping it light rather than dense.
- Shelled shrimps
- Adds sweet, savoury shellfish flavour to the forcemeat.
The step that matters
Forming the forcemeat balls. The pounded mixture must be bound well with the egg and kept moist with the soaked roll, or the balls will crumble or turn dense when cooked in the soup.
Swap the mace
How well each one fits the dish's main ingredients (meat, shrimp, parsley, milk, egg, pepper):
- Dillfits better
- Thymefits better
- Nutmegfits better
- Macethe original
Fit is the average pairing score against meat, shrimp, parsley, milk, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
