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 broth
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 and stew until the fish separates, then strain the mixture.
Prepare the garnish
Toast slices of bread until deep brown, then cut into triangles or squares.
Cut the carrot into four lengthwise slices.
Serve
In a tureen, place the toast and carrot, then pour the soup over them.
If desired, add boiling cream thickened with a little flour before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Provide the main body of the soup and flavour as they break down during stewing.
- Crust of bread
- Adds body and helps thicken the broth as it softens during stewing.
- Onion
- Contributes savoury sweetness and aroma to the broth as it cooks.
- Boiling cream
- Adds richness and a smooth, silky texture to the finished soup.
The step that matters
Stewing until the fish separates. Stewing gently until the eels fall apart releases their flesh and gelatin into the water, giving the broth its body. Cooking too briefly leaves the flavour weak, while boiling hard can make the broth cloudy.
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.
