Why it works: Parsley and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Celery Sauce
Ingredients
Directions
Prepare the celery
Strip the outer parts of the celery stems.
Wash the remaining portion of the celery.
Cut the celery into 2-inch pieces.
Boil the celery in a small amount of white broth until tender.
Make the sauce
Slice the onion thinly.
Place the sliced onion in a stewpan with parsley, thyme, and ham (if using).
Sweat the mixture in butter until the onions are done.
Stir in flour to thicken the sauce.
Mix the sauce well.
Gradually add the broth from the celery and enough boiling milk to achieve desired consistency.
Let the sauce boil for 20 minutes.
Strain the sauce through a fine sieve.
Add the cooked celery, salt, and sugar.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Forms the bulk of the sauce and gives it its characteristic flavor and body.
- Butter
- Fat that softens the onion and carries aroma into the sauce.
- Flour
- Thickens the sauce as it cooks with the liquid, giving it body.
- White broth
- Cooks the celery and forms the liquid base of the sauce.
- Milk
- Adds creaminess and smoothness to the sauce.
The step that matters
Adding the flour to the butter and onion. Flour must be cooked into the fat and mixed well before liquid is added; otherwise it clumps and the sauce thickens unevenly.
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.
