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

What each ingredient does

Liquor from boiled calf's head
Forms the savoury body and base flavour of the soup.
Egg yolks
Enrich the soup and thicken it gently when heated.
Milk
Adds creaminess and softens the broth's richness.
Corn-starch
Thickens the soup as it swells in hot liquid.
Onion
Adds savoury aroma to the broth.

The step that matters

Adding the boiling milk to the yolks. Hot milk must be combined with the beaten yolks carefully, so the yolks warm gradually and thicken smoothly. Added too quickly or too hot, the egg proteins can scramble into lumps instead of enriching the soup.

Swap the mace

How well each one fits the dish's main ingredients (onion, parsley, milk, egg, pepper, corn):

  1. Thymefits better
  2. Dillfits better
  3. Celeryfits better
  4. Macethe original

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