Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Cream Asparagus
Ingredients
Directions
Make the broth
Cook the veal knuckles slowly in 3 quarts of water with 1 tablespoon of salt for 2 hours, removing scum as it rises.
Strain the broth.
Make the soup
Boil the asparagus until tender.
In a separate pan, melt the butter until bubbling, then add the flour and mix well.
Gradually add the strained broth to the butter and flour mixture, stirring constantly until smooth.
Add the asparagus and the water it was boiled in to the soup, and heat until boiling.
Finish and serve
Just before serving, gradually pour the hot soup over the well-beaten egg yolks and cream, stirring constantly.

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
- Veal knuckles
- Release gelatin and flavour into the water, giving the broth body and savoury depth.
- Asparagus
- Provides the main flavour and green colour of the soup.
- Butter
- Carries flavour and enriches the soup while forming the base of the roux.
- Flour
- Cooked with butter to form a roux that thickens the broth.
- Egg yolks
- Enrich and thicken the soup, adding smoothness and richness when gently heated.
- Cream
- Adds richness and a silky texture to the finished soup.
The step that matters
Adding the hot soup to the egg yolks and cream. Egg yolks can curdle if they get too hot too quickly. Pouring the hot soup in gradually while stirring constantly tempers the yolks, so they thicken the soup smoothly instead of scrambling.
Swap the asparagus
How well each one fits the dish's main ingredients (veal, butter, flour, egg, cream):
- Leekfits better
- Chivefits about as well
- Asparagusthe original
- Shallotfits about as well
Fit is the average pairing score against veal, butter, flour, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
