Why it works: Celery and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Celery Soup
Ingredients
Directions
Make the soup
Combine chopped celery and water in a saucepan. Bring to a boil and cook until the celery is tender.
Strain the mixture through a sieve to remove solids and return the liquid to the saucepan.
Thicken and finish
In a small bowl, smooth the flour with a little milk, then add the remaining milk and mix well.
Add the milk mixture to the saucepan and stir to thicken the soup.
Season with salt and pepper to taste, then bring to a boil for a few minutes before serving.

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 as it cooks down in water.
- Flour
- Thickens the milk and broth into a smooth, creamy soup as it heats.
- Milk
- Adds creaminess and softness to the soup, mellowing its flavour.
- Butter
- Adds richness and a rounded, buttery flavour to the finished soup.
The step that matters
Smoothing the flour into the milk. Flour added directly to hot liquid clumps, because its starch grains coat in lumps before they can disperse. Mixing it first with a little cold milk into a smooth paste lets the starch spread evenly, so the soup thickens without lumps.
Swap the celery
How well each one fits the dish's main ingredients (milk, flour, pepper, butter):
- Cinnamonfits better
- Nutmegfits better
- Cardamomfits better
- Celerythe original
Fit is the average pairing score against milk, flour, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
