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

What each ingredient does

Calf's head liquor
Provides the rich, gelatinous body and meaty flavour of the broth.
Egg yolks
Enrich the soup and give it a smooth, thickened, creamy texture when heated.
Milk
Adds creaminess and mild sweetness, softening the savoury broth.
Corn starch
Thickens the broth slightly so it coats the spoon.

The step that matters

Adding the boiling milk to the beaten yolks. Egg yolks scramble if heated too fast. Mixing in the hot milk gradually, while beating, tempers them so the soup stays smooth and creamy rather than curdled.

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.
