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 ↓
Potato Balls
Ingredients
Directions
Make the potato mixture
Rub the cold boiled potatoes through a wire sieve into a stew-pan.
Add the butter and milk, then heat over the fire until smooth.
Stir in pepper, salt, egg yolk, and chopped parsley.
Let the mixture cool, then form it into balls.
Coat and fry
Brush the balls with egg white.
Roll the balls in bread crumbs.
Fry the balls in hot oil until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy base that holds the mixture together and gives it body.
- Butter
- Adds fat and richness, softening the potato for a smooth texture.
- Egg yolk
- Binds the mixture and helps it set firm when cooled and shaped.
- Egg white
- Gives the bread crumb coating a glue-like layer so it sticks to the balls.
- Bread crumbs
- Form a crisp outer crust that browns when fried.
The step that matters
Fry the balls in hot oil until golden brown. If the oil is not hot enough, the crumb coating absorbs oil and turns greasy, while the potato interior may not heat through. Oil that is hot enough seals the crust quickly, so the coating browns before the filling can soften and leak out.
Swap the parsley
How well each one fits the dish's main ingredients (potato, butter, milk, pepper, egg, bread):
- Parsleythe original
- Nutmegfits about as well
- Cinnamonfits less well
- Thymefits less well
Fit is the average pairing score against potato, butter, milk, pepper, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
