Cream Asparagus

Ingredients

Directions

Make the broth

  1. Cook the veal knuckles slowly in 3 quarts of water with 1 tablespoon of salt for 2 hours, removing scum as it rises.

  2. Strain the broth.

Make the soup

  1. Boil the asparagus until tender.

  2. In a separate pan, melt the butter until bubbling, then add the flour and mix well.

  3. Gradually add the strained broth to the butter and flour mixture, stirring constantly until smooth.

  4. Add the asparagus and the water it was boiled in to the soup, and heat until boiling.

Finish and serve

  1. Just before serving, gradually pour the hot soup over the well-beaten egg yolks and cream, stirring constantly.

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
