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

What each ingredient does

Cucumbers
Form the main body of the soup and give it its fresh, mild flavour.
Butter
Fat that cooks the cucumbers gently and carries flavour.
Flour
Thickens the soup as it cooks with the stock.
White stock iii
Forms the liquid base of the soup.
Milk
Adds creaminess and softness to the soup.
Egg yolks
Enrich and thicken the soup when added near the end.

The step that matters

Adding cream and egg yolks after reheating. Egg yolks thicken when heated but can curdle or scramble if the soup is at a hard boil. Reheat gently and keep the soup just below boiling once the yolks and cream go in, so it stays smooth.

Swap the mace

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

  1. Capersfits better
  2. Nutmegfits better
  3. Garlicfits better
  4. Macethe original

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