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

What each ingredient does

Egg yolks
Thicken the soup into a smooth, creamy texture when gently heated.
Butter
Adds richness and a silky mouthfeel to the finished soup.
Cream
Adds richness and body, softening the soup's flavor and texture.

The step that matters

Do not allow the soup to boil after adding the liaison. Egg yolks scramble and curdle when they get too hot, leaving the soup grainy instead of smooth. Keeping the heat low and stirring gently lets the yolks thicken it evenly.

Swap the potato

How well each one fits the dish's main ingredients (fish, leek, carrot, parsley, turnip, cream, egg):

  1. Parsnipfits better
  2. Shallotfits better
  3. Chivefits better
  4. Potatothe original

Fit is the average pairing score against fish, leek, carrot, parsley, turnip, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
