Why it works: Pepper and carrot match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 14,555 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Eel Soup
Ingredients
Directions
Prepare the eels
Clean and cut the eels into pieces.
In a pot, combine eels and water.
Make the soup
Add onion, mace, whole pepper, sweet herbs, and bread crust.
Cover and simmer until the fish separates, then strain the mixture.
Assemble and serve
Toast the bread until deep brown, then cut into triangles or squares.
Place the carrot slices in a tureen with the toast.
Pour the strained soup over the toast and carrot.
If desired, add boiling cream thickened with flour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Provide the main flavour and body of the soup as they break down while simmering.
- Bread
- Toasted bread gives a deep brown colour and soaks up the soup as the base for serving.
- Flour
- Thickens the optional boiling cream so it lightly coats the soup.
The step that matters
Simmer until the fish separates. Simmering gently lets the eels release their flavour and collagen slowly; a hard boil can cloud the broth and toughen the flesh, so watch for the fish to separate rather than rushing it.
Swap the mace
How well each one fits the dish's main ingredients (onion, pepper, bread, carrot, cream, flour):
- Celeryfits better
- Parsleyfits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against onion, pepper, bread, carrot, cream, flour. Candidates are from the same food group and used in at least 100 recipes.
