Why it works: Milk and butter 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
Remove the green leaves from the tops of the celery and cut it into short slips.
Wash the celery well and soak it in cold water for 1 hour.
Make the sauce
In a saucepan, combine the milk and butter that has been dredged with flour.
Heat the mixture over low heat and gradually add the celery and broken mace.
Add the green tops of the celery when it begins to simmer for added flavor.
Boil slowly until the celery is soft but not dissolved.

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 flavor and body of the sauce as it softens.
- Milk
- Forms the liquid base of the sauce that the celery cooks in.
- Butter
- Adds richness and fat, carrying flavor and giving the sauce a smooth mouthfeel.
- Flour
- Thickens the milk and butter mixture, giving the sauce body.
- Mace
- Adds a warm, aromatic spice flavor to the milk.
The step that matters
Boil slowly until the celery is soft but not dissolved. Flour-thickened milk can scorch or turn lumpy if heated too fast, and overcooking breaks celery down so it loses its texture. Gentle heat keeps the sauce smooth and the celery intact.
Swap the mace
How well each one fits the dish's main ingredients (celery, milk, butter, flour):
- Cinnamonfits better
- Nutmegfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against celery, milk, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
