Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Celery Soup
Ingredients
Directions
Prepare the celery
Cut the celery into 1‑inch lengths.
Combine the celery and water in a pot and cook until tender.
Remove the celery and rub it through a sieve.
Make the soup
Add the sieved celery to the soup stock and cook slowly for 30 minutes.
Heat the cream and stir in the flour mixed with the butter.
Pour the cream mixture into the soup and heat until very hot, but do not boil.
Serve immediately.

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, once sieved, the body of the soup.
- Soup stock
- Supplies the savoury base that the sieved celery is cooked into.
- Cream
- Adds richness and a smooth, velvety texture to the finished soup.
- Flour
- Thickens the soup slightly when cooked with the butter and cream.
- Butter
- Adds fat and flavour, and helps the flour blend smoothly into the cream.
The step that matters
Heating the cream mixture without boiling. Boiling a cream-based soup can cause the dairy to separate and the texture to turn grainy. Heating it gently until very hot keeps it smooth.
Swap the celery
How well each one fits the dish's main ingredients (cream, flour, butter):
- Nutmegfits better
- Jalapenofits better
- Capersfits better
- Celerythe original
Fit is the average pairing score against cream, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
