Why it works: Truffle and butter are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 2,209 recipes. Both carry nonanal, which smells fat, citrus. The science ↓
Calf’s Head Hashed
Ingredients
Directions
Prepare the meat
Parboil the calf's head and tongue.
Cut the meat into thin slices.
Make the hash
Stew the meat in good gravy for about 1 hour.

Thicken the gravy with butter and flour just before serving.
Make the brain cakes and serve
Scald the brains and beat them with eggs, flour, lemon peel, parsley, and herbs.
Form the mixture into small cakes and fry in boiling lard until brown.
Serve the hash with gravy, mushrooms, forcemeat balls, and brain cakes.

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, becoming tender when parboiled and stewed in gravy.
- Eggs
- Bind the brain mixture so the cakes hold their shape while frying.
- Butter and flour
- Thicken the gravy to a smooth, coating consistency just before serving.
- Truffles and morels
- Add earthy, aromatic flavour to the gravy during stewing.
- Brains (in the method)
- Form the soft interior of the brain cakes, enriched by the eggs and flour.
The step that matters
Frying the brain cakes in boiling lard until brown. Lard must be hot enough to brown the outside quickly. If it is too cool, the cakes absorb fat and turn greasy before a crisp crust forms, and the soft egg-bound interior can break apart.
Swap the mace
How well each one fits the dish's main ingredients (anchovy, pepper, truffle, wine, butter, flour, egg):
- Parsleyfits better
- Capersfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against anchovy, pepper, truffle, wine, butter, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
