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 celery
Break the celery into pieces and pound in a mortar.
Make the soup
Add the celery to the milk and cook in a double boiler for 20 minutes.
In a separate pan, melt the butter and mix with the flour to create a roux.
Thicken the soup with the roux, then season with salt and pepper.
Add the cream, strain the soup, and serve.

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.

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 of the soup.
- Milk
- Forms the liquid base that the soup cooks in.
- Butter
- Adds richness and fat to the roux.
- Flour
- Thickens the soup when cooked with butter into a roux.
- Cream
- Adds richness and a smoother, silkier texture.
The step that matters
Making the roux. Flour must be cooked briefly in melted butter before it is added to the soup. Cooking it removes the raw starchy taste and lets the flour thicken smoothly without lumps.
Swap the celery
How well each one fits the dish's main ingredients (milk, butter, flour, cream, pepper):
- Nutmegfits better
- Cinnamonfits better
- Cardamomfits about as well
- Celerythe original
Fit is the average pairing score against milk, butter, flour, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
