Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Cream of Celery Soup
Ingredients
Directions
Prepare the celery
Cut the green portions of the celery into small pieces, about 12 to 14 stalks.
Cover the celery with ½ cup of cold water, bring to a boil, and simmer for 30 minutes.
Drain and press the celery through a colander to extract as much liquid as possible.
Make the soup
Add 1 pint of milk to the celery liquid in a double boiler.
In a separate bowl, rub together 1 tablespoon of butter and 2 tablespoons of flour, then stir into the soup.
Stir and cook until the soup is smooth.
Add 1 teaspoon of celery salt and a dash of white pepper before serving.

Butter and flour 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 flavor and body of the soup once simmered and pressed.
- Milk
- Forms the creamy base of the soup and carries the celery flavor.
- Flour
- Thickens the soup as it cooks, giving it a smooth, body-rich texture.
- Butter
- Adds richness and helps the flour blend smoothly into the soup.
The step that matters
Stirring in the butter and flour mixture. Flour clumps if added raw to hot liquid. Rubbing it with butter first coats the starch grains so they disperse, and stirring keeps the soup smooth as it thickens.
Swap the white pepper
How well each one fits the dish's main ingredients (celery, milk, butter, flour):
- Cinnamonfits better
- Nutmegfits better
- Parsleyfits better
- White pepperthe original
Fit is the average pairing score against celery, milk, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
