Ingredients
Directions
Prepare the celery
Clean and wash the celery, trimming off the green parts.
Cut the tender parts into 1-inch pieces and slice the celery roots finely.
Parboil the celery and roots for 5 minutes, then immerse in cold water, drain, and dry.
Make the soup
In a saucepan, melt the butter and add the celery and roots, seasoning with salt, pepper, nutmeg, and sugar.
Cover and simmer until moisture is reduced.
Add the white broth and a bunch of parsley.

Boil until the celery is well cooked.
Add the thickened veal or chicken broth.
Boil slowly for 20 minutes.
Remove the parsley bundle.

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 gives its main flavour and texture once cooked and strained.
- Celery roots
- Add a deeper, earthy celery flavour and help thicken the soup as they cook down.
- Cream
- Adds richness and a smooth, velvety mouthfeel to the finished soup.
- Egg yolks
- Enrich and thicken the soup gently when stirred in off the heat, adding smoothness.
- Butter
- Adds fat for rich flavour and a silky mouthfeel to the soup.
- Broth
- Provides the liquid base and savoury depth of the soup.
The step that matters
Mix in the cream, egg yolks, and butter off the heat. Egg yolks thicken by gentle heat; if the soup is boiling when they are added, they can scramble and turn grainy. Removing the pan from the heat keeps the liquid smooth and silky.
Swap the onion
How well each one fits the dish's main ingredients (celery, butter, pepper, nutmeg, sugar, parsley, leek):
