Prepare the broth

  1. Boil the broth gently for 2 hours, skimming off the fat as it rises.

  2. Wash and peel the Jerusalem artichokes, then add them to the broth.

  3. Boil the artichokes until tender enough to rub through a cloth.

Make the soup

  1. Strain the broth and return the artichokes to the stewpan with a little salt.

  2. Bring the mixture to a boil, skimming off any scum that rises.

  3. Mix in the boiling cream and beaten egg yolks.

Serve

  1. Serve with or without toasted bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Jerusalem artichokes
Provide the main body and thickening starch once boiled and rubbed through a cloth.
Broth
Forms the liquid base that carries the flavor of the soup.
Cream
Adds richness and a smooth, velvety mouthfeel to the soup.
Egg yolks
Enrich and thicken the soup slightly when stirred into the hot mixture.

The step that matters

Mixing in the egg yolks. Egg yolks thicken through gentle heat; if the soup boils after they go in, they can curdle and turn grainy. Add them off the heat or with the soup just below a simmer.

How well each one fits the dish's main ingredients (cream, egg, bread):

  1. Asparagusfits about as well
  2. Jerusalem artichokethe original
  3. Leekfits about as well
