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
Wash and scrape the celery, then cut it into 1‑inch pieces.
Cover the celery with 1 quart of water or white stock and cook slowly for 45 minutes until tender.
Press the cooked celery through a puree sieve.
Finish the soup
Add 1 quart of hot milk and bring to a boil.
Thicken the soup with 2 tablespoons of flour blended with 2 tablespoons of butter, stirring constantly until smooth and creamy.
Stir in 1 tablespoon of minced parsley and ½ cup of cream.
Serve with souffle balls.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Provides the main flavour and body of the soup once cooked and pureed.
- Flour
- Thickens the soup as it heats, giving it a smooth, creamy texture.
- Butter
- Combines with the flour to form a roux that helps thicken the soup and adds richness.
- Milk
- Adds creaminess and body, mellowing the soup's flavour.
- Cream
- Adds richness and a silky texture to the finished soup.
The step that matters
Thickening with flour and butter. Stirring constantly keeps the flour from clumping. Cooking the flour and butter together until smooth lets the starch swell evenly, so the soup thickens without lumps.
Swap the celery
How well each one fits the dish's main ingredients (milk, flour, butter, parsley, cream):
- Nutmegfits better
- Cinnamonfits better
- Capersfits better
- Celerythe original
Fit is the average pairing score against milk, flour, butter, parsley, cream. Candidates are from the same food group and used in at least 100 recipes.
