Celery Sauce
Ingredients
Directions
Prepare the celery
Strip the outer parts of the celery stems, wash the remaining portion, and cut into 2-inch pieces.
Boil the celery pieces in a small amount of white broth until tender.
Make the sauce
In a stewpan, melt the butter and add the onion, parsley, thyme, and ham (if using); sweat until the onions are done.
Stir in the flour to thicken the sauce, then gradually mix in the celery broth and the boiling milk.
Let the mixture boil for 20 minutes, then strain through a fine sieve.
Add the cooked celery, salt, and sugar, and serve hot and thick.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Provides the main flavour and, once cooked and strained, the body of the sauce.
- Butter
- Carries the aromatics in the pan and adds richness to the sauce.
- All-purpose flour
- Thickens the sauce as it cooks with the liquids, giving it a smooth, thick texture.
- White broth
- Cooks the celery and forms the liquid base that gives the sauce its savoury depth.
- Milk
- Adds creaminess and mild sweetness, softening the savoury flavour of the sauce.
- Onion
- Sweats in butter to release sweet, aromatic flavour into the sauce.
The step that matters
Thickening with flour before adding liquid. Flour must be cooked briefly in the melted butter and whisked in gradually with the broth and boiling milk to avoid lumps and to thicken the sauce evenly.
Swap the onion
How well each one fits the dish's main ingredients (celery, parsley, thyme, ham, butter, flour, milk):
- Carrotfits better
- Leekfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against celery, parsley, thyme, ham, butter, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
