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 ↓
Cream of Celery Soup
Ingredients
Directions
Prepare the celery
Clean, wash, and finely chop the leaves and coarse stalks of the celery.
In a saucepan, melt the butter or drippings and add the celery, chopped onion, and parsley.
Cover and cook on low heat, stirring occasionally, until the celery is tender.
Add the broth or hot water and cook slowly until very tender.
Pass the soup through a fine sieve.
Make the roux and finish
In a separate pan, cook the flour in melted butter, then gradually add enough milk to make a quart of soup.
Combine the soup with the roux and bring to a boil until smooth.
Stir in the cream and beaten egg yolks (if using) and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Forms the main body and flavor of the soup as it softens and breaks down.
- Flour
- Thickens the soup with the butter roux, giving it a smooth, body-rich texture.
- Butter
- Carries flavor and cooks the flour into a roux for thickening.
- Cream
- Adds richness and a smooth, velvety mouthfeel to the finished soup.
- Egg yolks
- Enrich and further thicken the soup when stirred in at the end.
The step that matters
Stirring in the cream and egg yolks. Once the soup is boiling, egg yolks can curdle or scramble if added too hot or boiled after adding, so they should be stirred in gently and the soup served right away.
Swap the parsley
