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

What each ingredient does

Calf's head
Forms the main body of the hash, providing the meat that is sliced and stewed.
Butter
Combined with flour to thicken the stew, adding richness and body to the gravy.
Eggs
Bind the brain mixture so it holds together when formed into cakes.
Flour
Thickens the gravy with butter and helps bind the brain cakes.
Walnut ketchup
Adds a sharp, savoury depth of flavour to the stew.
Truffles or morels
Contribute a earthy, aromatic flavour to the stew.

The step that matters

Frying the brain cakes in hot lard until brown. Frying in hot fat sets the egg-bound outside quickly and browns it, so the cakes hold their shape. If the fat is not hot enough, the cakes absorb grease and may break apart.

Swap the mace

How well each one fits the dish's main ingredients (anchovy, pepper, lemon, walnut, ketchup, truffle, white wine):

  1. Parsleyfits better
  2. Thymefits better
  3. Tarragonfits better
  4. Macethe original

Fit is the average pairing score against anchovy, pepper, lemon, walnut, ketchup, truffle, white wine. Candidates are from the same food group and used in at least 100 recipes.
