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-puree, with Croutons
Ingredients
Directions
Prepare the chicory
Boil chicory heads in salted water until only the white parts remain.
Drain and press out excess water, then chop the chicory.
Make the puree

Add chopped chicory and fry for a few minutes, stirring frequently.
Sprinkle flour over the chicory, then moisten with broth and boiled milk.
Stir until boiling, season to taste, and reduce heat to simmer for 30 minutes.
Pass the mixture through a fine sieve or tammy.
Thicken with a liaison of egg yolks mixed with cream.
Serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicory
- Provides the main vegetable body and bitter flavour of the puree.
- Butter
- Adds fat and richness while the chicory softens and fries.
- Flour
- Lightly thickens the liquid as it cooks with the chicory.
- Broth
- Supplies the liquid that cooks the chicory into a pourable puree.
- Milk
- Adds creaminess and softens the flavour of the puree.
- Egg yolks (in the method)
- Thicken the finished puree into a smooth, velvety texture.
The step that matters
Thicken with the egg liaison. Egg yolks set when heated, so the liaison can curdle or turn grainy if the puree is boiling. Add it off the heat or on very low heat, stirring constantly, to keep the texture smooth.
