Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ingredients
Directions
Make the base
Melt 3 teaspoons of butter in a saucepan.
Add 3 tablespoons each of chopped celery, turnip, and carrot, 1 tablespoon minced onion, bay leaf, blade of mace, and a bit of parsley.
Cook for 30 minutes, stirring to prevent browning.
Add 3 tablespoons of flour and blend until smooth.
Make the soup
Gradually pour in 3 pints of hot milk.
Cook in a double boiler for 30 minutes more.
Season with salt and pepper and strain.
Finish and serve
Add 3 beaten yolks with half a cup of cream just before serving.
Serve with croutons.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Flour
- Forms a roux with the butter that thickens the milk into a smooth soup.
- Milk
- Forms the liquid base of the soup, which the roux thickens.
- Egg yolks
- Enrich the soup and add richness and body when stirred in at the end.
- Butter
- Fat that cooks the vegetables and forms the roux with the flour.
- Celery
- Adds savory vegetable flavor to the soup base.
The step that matters
Add the beaten yolks just before serving. Egg yolks thicken and enrich when gently heated, but if they are boiled they can scramble and curdle, so they should be added off the heat or at the last moment.
Swap the mace
How well each one fits the dish's main ingredients (butter, sauce, celery, onion, flour, milk, parsley):
- Capersfits better
- Thymefits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against butter, sauce, celery, onion, flour, milk, parsley. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
