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 ↓
Brain Fritters
Ingredients
Directions
Prepare the brain
Wash the ox brain and boil it in well-seasoned stock for 15 minutes.
Once cooled, slice the brain as thinly as possible.
Make the batter
Mix flour, cold water, dissolved butter or oil, egg yolk, salt, and pepper to make the batter.
Let the batter stand for 2 hours.
Beat the egg white to a strong froth and fold it into the batter.
Fry and serve
Heat fat to 430°F (220°C).
Dip each brain slice in the batter and fry two fritters at a time until golden.
Remove fritters and place them on paper to absorb excess grease.
Garnish with fried parsley and serve.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox brain
- Forms the main body of the fritter, providing a soft, rich filling inside the batter.
- Flour
- Forms the batter that coats the slices and sets into a crisp, golden shell when fried.
- Egg yolk
- Adds richness and helps bind the batter so it clings to the brain slices.
- Egg white
- Whipped to a froth and folded in, it lightens the batter and makes it puff when fried.
- Butter or fine oil
- Adds fat that tenderises the batter and helps it brown evenly in the pan.
The step that matters
Folding in the beaten egg white. Whites beaten to a strong froth trap air that expands in hot fat. Folding gently keeps that air in the batter, so the fritters puff and stay light instead of turning dense.
Swap the parsley
How well each one fits the dish's main ingredients (flour, butter, egg, pepper):
- Parsleythe original
- Nutmegfits about as well
- Capersfits less well
- Tarragonfits less well
Fit is the average pairing score against flour, butter, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
