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, and cut into 2-inch pieces.
Boil the celery in a small amount of good white broth until tender.
Make the sauce
Slice the onion thinly and place it in a stewpan with parsley, thyme, and ham (if using).
Sweat the mixture in a little butter until the onions are soft.
Stir in enough flour to thicken the sauce.
Gradually mix in the broth from the celery and enough boiling new milk.
Let it boil for 20 minutes.
Strain through a fine sieve.
Finish and serve
Add the cooked celery, season with salt and a little sugar, and 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 main body and flavour of the sauce once boiled until tender.
- Butter
- Softens the onions in fat, building a mellow base for the sauce.
- Flour
- Thickens the liquid into a smooth, coating sauce.
- New milk
- Adds creaminess and richness, softening the sauce's texture.
- White broth
- Provides savoury liquid that cooks the celery and carries its flavour into the sauce.
The step that matters
Gradually mixing in the broth and boiling milk. Adding liquid slowly to flour-thickened fat lets starch granules separate and swell evenly. Adding it all at once can leave lumps that a sieve must then remove.
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.
