Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Eel Soup with Two Eggs
Ingredients
Directions
Prepare the eels
Clean, skin, and remove fat from the eels.
Fry the eels in drippings from the salt pork for 5 minutes.
Make the soup
Add water, onion, celery (or seeds), salt, and pepper; boil until tender, about 1 hour.
Remove eels to a tureen and strain the soup back into the kettle.
Thicken the soup with a beaten egg mixed with flour and milk.
Serve
Pour the thickened soup over the eels in the tureen.
Slice the hard-boiled eggs and add them to the tureen.
Garnish with chopped parsley if desired and serve with toasted bread.

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 and rich flavor of the soup.
- Flour
- Thickens the soup as it is cooked with the liquid.
- Milk
- Adds creaminess and softness to the thickened soup.
- Eggs
- Add richness and body to the thickened soup, and are served sliced as a garnish.
The step that matters
Thicken the soup with the egg, flour, and milk mixture. Adding a thickener to hot liquid can clump if it is not blended smoothly first. Mixing the flour and milk into a smooth paste before adding it keeps the soup evenly thickened.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (pork, onion, celery, pepper, flour, milk, egg):
- Parsleythe original
- Thymefits about as well
- Turmericfits about as well
- Marjoramfits about as well
Fit is the average pairing score against pork, onion, celery, pepper, flour, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
