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):
- Parsleyfits better
- Thymefits better
- Tarragonfits better
- 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.
