The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Salsify
Forms the main body of the soup and gives its flavour.
Eggs
Yolks enrich the soup and thicken it slightly when added at the end.
Cream
Adds richness and a smooth, silky mouthfeel.
Butter
Adds fat and richness, and with flour helps thicken the soup.
Flour (in the method)
Thickens the soup when cooked with butter into a roux.

The step that matters

Adding the egg and cream mixture. Egg yolks can curdle if they get too hot. Add them off the heat or at the last moment, and stir gently, so the soup stays smooth and thick.

Swap the white pepper

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

  1. Nutmegfits better
  2. Garlicfits better
  3. Capersfits better
  4. White pepperthe original

Fit is the average pairing score against onion, butter, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
