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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Provide the main body of the balls, with cooked yolks mashed to a soft, crumbly base.
- Raw egg yolk
- Acts as a binder that helps the mashed yolk mixture hold together when formed into balls.
- Flour
- Absorbs moisture and adds body, helping the mixture keep its shape while cooking.
The step that matters
Boil the balls in water for two minutes. Raw egg yolk in the mixture sets when heated, so the balls need enough heat to hold their shape. Boiling only briefly keeps them from breaking apart or becoming tough.
Swap the parsley
How well each one fits the dish's main ingredients (egg, flour, pepper):
- Turmericfits about as well
- Parsleythe original
- Nutmegfits about as well
- Jalapenofits about as well
Fit is the average pairing score against egg, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
