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 ↓
Cream of Asparagus
Ingredients
Directions
Prepare the pulp
Boil the tough parts of the asparagus stalks until tender, then mash and sieve to obtain 1 cup of pulp.
Make the soup
In a saucepan, melt the butter and flour together until smooth.
Gradually stir in the milk and enough asparagus water to achieve a creamy soup consistency.
Add the asparagus pulp and stir until smooth, then bring to a boil.
Season with salt, white pepper, and nutmeg, then remove from heat.
Finish and serve
Beat the egg yolk with a little soup, then stir it into the soup mixture.
Serve immediately, ensuring the soup does not boil after adding the egg.

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
- Butter
- Enriches the soup and carries flavour while it is melted with the flour.
- Flour
- Thickens the milk into a smooth, creamy base when cooked with the butter.
- Milk
- Forms the creamy body of the soup.
- Asparagus pulp
- Gives the soup its main asparagus flavour and body.
- Egg yolk
- Enriches and thickens the finished soup for a richer texture.
The step that matters
Adding the egg yolk. Egg yolk thickens by gentle heat. If the soup boils after the yolk goes in, the egg can curdle and the texture turns grainy. Beating the yolk with some hot soup first helps it blend smoothly.
Swap the white pepper
How well each one fits the dish's main ingredients (butter, flour, milk, asparagus, nutmeg, egg):
- Cinnamonfits better
- Tarragonfits better
- Capersfits better
- White pepperthe original
Fit is the average pairing score against butter, flour, milk, asparagus, nutmeg, egg. Candidates are from the same food group and used in at least 100 recipes.
