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
Make the stock
Cut the eels into pieces and place them in a pot.
Add water, onion, mace, whole pepper, sweet herbs, and the crust of bread.
Cover the pot and stew until the fish separates.
Strain the mixture.
Prepare the toast and carrot
Toast slices of bread until deep brown, then cut the toast into triangles or squares.
Cut the carrot into four lengthwise slices.
Assemble and serve
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 a little 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 flesh and body of the soup as they break down during stewing.
- Bread crust
- Soaks up and helps thicken the broth as it stews with the fish.
- Toasted bread
- Soaks up the strained soup, giving a soft, absorbent base in the tureen.
- Boiling cream
- Adds richness and body to the soup, thickened with flour when used.
The step that matters
Stewing until the fish separates. Cooking gently under a cover lets the eels break down slowly, releasing gelatin and flavour into the broth. Stopping too early leaves a weak soup, while overcooking can make the broth cloudy and muddy.
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.
