Why it works: Butter and truffle are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 2,209 recipes. Both carry nonanal, which smells fat, citrus. The science ↓

Ingredients
Directions
Prepare the celery
Blanch the celery in boiling water for a few minutes.
Make the sauce
Cook the blanched celery in the stock until tender.
In a separate pan, melt the butter and stir in the flour to make a roux.
Add the roux to the stock and celery, stirring to thicken.
Simmer for a few minutes, then serve with optional truffle slices.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Forms the main body of the dish and becomes tender as it cooks in the stock.
- Stock
- Provides the liquid and savory flavor that the sauce is built on.
- Flour
- Thickens the liquid when cooked with butter into a roux.
- Butter
- Carries the flour in the roux and adds richness to the sauce.
The step that matters
Adding the roux to the stock. Whisk the roux into the hot liquid while stirring so the flour disperses evenly; dumping it in at once can form lumps that do not smooth out, and the sauce will not thicken evenly.
Swap the celery
How well each one fits the dish's main ingredients (flour, butter, truffle):
- Capersfits better
- Nutmegfits better
- Parsleyfits better
- Celerythe original
Fit is the average pairing score against flour, butter, truffle. Candidates are from the same food group and used in at least 100 recipes.
