Why it works: Butter and milk 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 ↓
Chicory Soup
Ingredients
Directions
Prepare the chicory
Trim the chicory and boil until half cooked, then drain and mince finely.
Mix the minced chicory with flour, butter, and a sprinkling of pepper, salt, and mace.
Make the soup
Place the mixture in a saucepan with white stock and boiling milk.
Cook carefully for 1 hour.
Beat the egg yolks in ½ cup of milk and add to the soup after it has gone off the boil.
Strain the soup through a fine sieve and serve immediately.

Flour and butter 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
- Chicory
- Provides the main bitter vegetable flavour and body of the soup.
- Flour
- Thickens the soup by absorbing liquid as it cooks.
- Butter
- Adds richness and a smooth, rounded mouthfeel.
- Egg yolks
- Enrich and thicken the soup, giving it a silkier texture.
- White stock
- Forms the liquid base that carries the soup's flavour.
The step that matters
Adding the egg yolks. Egg yolks can curdle or scramble if the soup is too hot. Adding them after it has come off the boil lets them thicken gently and stay smooth.
Swap the mace
How well each one fits the dish's main ingredients (chicory, flour, butter, pepper, milk, egg):
- Nutmegfits better
- Parsleyfits better
- Cinnamonfits better
- Macethe original
Fit is the average pairing score against chicory, flour, butter, pepper, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
