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 ↓
Celery Soup Puree, Spanish Style
Ingredients
Directions
Prepare the celery
Clean and wash the celery, trimming off all green parts.
Cut the tender parts into 1-inch pieces and mix with the sliced celery roots.
Parboil the celery and roots for 5 minutes.
Immerse in cold water, drain, and dry.
Make the soup
In a saucepan, melt the butter and add the celery mixture.
Season with salt, pepper, nutmeg, and sugar.
Cover and simmer until moisture is reduced.
Add the white broth and the faggot of parsley, garnished with leeks and green onions.
Boil until the celery is well cooked.
Add the thickened veal or chicken broth and boil slowly for 20 minutes.
Remove the faggot and strain the soup through a fine sieve.
Return the soup to the saucepan to keep warm.
Finish and serve
When ready to serve, mix in the cream, diluted with the egg yolks, and the butter until melted.
Garnish with chopped parsley and serve with small fried bread crumbs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Forms the body of the soup, and as it cooks down it gives the soup its flavour and body.
- Celery roots
- Add a dense, earthy flavour and help thicken the soup as they break down.
- Butter
- Adds richness and a smooth mouthfeel to the soup.
- Thickened veal or chicken broth
- Provides the main liquid and savoury depth for the soup.
- Cream
- Adds richness and a silky texture to the finished soup.
- Egg yolks
- Enrich and thicken the cream, giving the soup a smoother, velvety body.
The step that matters
Mixing in the cream and egg yolks. Egg yolks thicken when heated, so if the soup is too hot when they are added, they can scramble and turn grainy. Diluting them with cream and adding them off the heat keeps the texture smooth.
Swap the onion
How well each one fits the dish's main ingredients (celery, butter, pepper, nutmeg, sugar, parsley, leek):
- Carrotfits better
