Why it works: Parsley and pepper 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 ↓

Egg and flour barely smell alike, yet cooks put them together in 106,462 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
- Hard-boiled egg yolks
- Form the main body of the balls, giving a crumbly, rich texture.
- Raw egg yolk
- Binds the pounded mixture so the balls hold their shape.
- Flour
- Absorbs moisture and helps the mixture hold together when rolled and cooked.
The step that matters
Boil the balls for 2 minutes. Boiling briefly sets the raw egg yolk binder so the balls hold their shape. Boiling too long can make them tough or cause them to break apart in the water.
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.
