Why it works: Butter and milk 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 ↓
Celery Sauce
Ingredients
Directions
Prepare the celery
In a small saucepan, combine the celery and stock or water.
Add ¾ teaspoon of salt, cover, and boil for 15 to 20 minutes until the celery is tender.
Drain the celery, reserving the liquid, and add enough liquid back to the celery to make ¾ cup.
Make the sauce
In another saucepan, melt the butter and stir in the flour.
Gradually pour in the prepared liquid, stirring until boiling.
Season with white pepper to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts with the flour to form a roux that thickens the sauce and adds richness.
- Flour
- Thickens the sauce when cooked in butter and combined with the liquid.
- Rich milk
- Adds creaminess and body to the sauce.
- Celery
- Provides the main flavor and tender texture of the sauce.
The step that matters
Gradually pour in the prepared liquid, stirring until boiling. Adding liquid slowly while stirring keeps the flour evenly dispersed, preventing lumps and allowing the starch to thicken the sauce smoothly as it boils.
Swap the white pepper
How well each one fits the dish's main ingredients (celery, butter, flour, milk):
- Cinnamonfits better
- Nutmegfits better
- Parsleyfits better
- White pepperthe original
Fit is the average pairing score against celery, butter, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
