Pepper and mace barely smell alike, yet cooks put them together in 12,257 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haddock
- Forms the main body of the soup and, once pulped, gives it flavour and substance.
- Shrimps
- Adds sweet, delicate seafood flavour to the pounded fish balls.
- French roll
- Soaked in cream and crumbed, it binds the fish mixture and keeps the balls tender.
- Egg
- Binds the pounded fish and crumb mixture so it holds together when shaped into balls.
- Flour and butter
- Together form a roux that thickens the soup to a smooth, body-rich texture.
The step that matters
Forming the fish balls. The mixture must be pounded and bound with egg and crumb so it holds its shape without becoming stiff or falling apart when cooked in the soup.
Swap the mace
How well each one fits the dish's main ingredients (shrimp, meat, haddock, parsley, cream, egg, pepper):
- Dillfits better
- Capersfits better
- Nutmegfits better
- Macethe original
Fit is the average pairing score against shrimp, meat, haddock, parsley, cream, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
