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 ↓
Cream of Celery Soup
Ingredients
Directions
Prepare the vegetables
Cut the outer stalks of celery into very small dice.
Boil the diced celery in water for 5 minutes.
Drain the celery.
Make the soup
Boil the soup stock with onions and ham.
In a saucepan, stir together the butter and flour.
Add the butter and flour mixture to the stock.
Once it boils and thickens, strain it into another saucepan.
Add the boiled celery.
Cook for over 30 minutes until done.
Finish and serve
Heat the milk.
Add the heated milk to the soup along with salt, pepper, and minced green celery leaf or parsley.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 vegetable flavour and body of the soup.
- Flour
- Combined with butter to form a roux that thickens the soup.
- Butter
- Enriches the flavour and, with flour, helps thicken the soup.
- Milk
- Adds creaminess and smoothness to the finished soup.
- Soup stock
- Forms the liquid base that carries the flavour of the soup.
The step that matters
Adding the butter and flour mixture to the stock. Flour must be cooked into the butter and liquid so it thickens smoothly. Added to hot stock with stirring, it dissolves evenly; added cold or unstirred, it can form lumps.
Swap the onion
How well each one fits the dish's main ingredients (milk, ham, celery, flour, butter, pepper):
- Carrotfits better

- Leekfits better
- Onionthe original
Fit is the average pairing score against milk, ham, celery, flour, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
