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
Cut the celery into 1-inch pieces and boil in water until tender.
Make the sauce
Melt the butter in a saucepan and stir in the flour to make a roux.
Gradually add the milk, stirring until the sauce thickens.
Add the cooked celery to the sauce and season with salt and white pepper.
Finish and serve
Stir in the cream, let it boil briefly, and serve immediately.

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 vegetable flavour of the sauce.
- Butter
- Adds richness and carries flavour, and forms the base of the roux.
- Flour
- Thickens the sauce as its starch swells with heat and liquid.
- Milk
- Forms the liquid base that the roux thickens into a smooth sauce.
- Cream
- Adds richness and a silky texture to the finished sauce.
The step that matters
Cooking the roux before adding the milk. Stirring the flour into melted butter and cooking it briefly coats the starch granules in fat, so they disperse evenly in the milk. Adding liquid too early or too fast can cause lumps and leave a raw floury taste.
Swap the white pepper
How well each one fits the dish's main ingredients (celery, butter, flour, milk, cream):
- Nutmegfits better
- Cinnamonfits better
- Tarragonfits better
- White pepperthe original
Fit is the average pairing score against celery, butter, flour, milk, cream. Candidates are from the same food group and used in at least 100 recipes.
