Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Cervelles De Veau En Marinade — Calf’s Brains En Marinade
Ingredients
Directions
Prepare the brains
Remove the brains from the calves’ heads and clean them thoroughly.
Stew the brains in white wine and stock, adding salt, pepper, parsley, and green onions.

Dip each piece in the paste.
Fry the pieces until golden.
Serve the fried brains with the ragout of small onions and roots on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf brains
- Form the main body of the dish, becoming tender when stewed and firm when fried.
- Flour
- Forms the paste that coats the brains and crisps into a golden crust when fried.
- Eggs
- Bind the paste and help it set and brown during frying.
- White wine
- Adds acidity and aroma to the stewing liquid, flavouring the brains.
- Butter
- Adds fat and richness to the paste, aiding browning.
The step that matters
Frying the coated brains until golden. Frying at a steady heat sets the egg and flour coating into a crisp, golden crust while keeping the brains moist inside. Too little heat soaks the coating with oil, and too much heat burns it before the centre is cooked through.
Swap the onion
How well each one fits the dish's main ingredients (white wine, pepper, parsley, flour, butter, egg):
- Shallotfits better
- Chivefits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against white wine, pepper, parsley, flour, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
