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 base
Cook the celery in the white stock for 45 minutes.
Bring the milk to a boil.
Mix the flour with a little milk, then stir it into the boiling milk.
Strain the cooked celery and stock through a fine sieve, mashing the celery through.
Finish and serve
Add the strained mixture to the milk and bring to a boil for 5 minutes, stirring thoroughly.
Season with salt and pepper, then stir in the cream just before serving.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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, once cooked and mashed, the body of the soup.
- Flour
- Thickens the milk as it heats, giving the soup a smooth, velvety body.
- Milk
- Forms the creamy base of the soup and carries the flavour.
- Cream
- Adds richness and a silky texture when stirred in at the end.
The step that matters
Stirring the flour into the boiling milk. Flour mixed in as a paste with a little milk disperses evenly. Added to hot liquid without this, it can clump, leaving lumps that a smooth soup should not have.
Swap the celery
How well each one fits the dish's main ingredients (milk, flour, cream, pepper):
- Nutmegfits better
- Cardamomfits better
- Cinnamonfits about as well
- Celerythe original
Fit is the average pairing score against milk, flour, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
