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 ↓

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 eggs
- Their mashed yolks form the main body of the balls.
- Raw egg yolk
- Binds the mashed yolks together so the mixture holds its shape.
- Flour
- Adds body and helps the mixture hold together when formed and boiled.
The step that matters
Forming the balls with a firm mixture. If the mixture is too wet or loose, the balls will fall apart in the boiling water. Mashing the yolks well with the raw yolk and flour gives a cohesive dough that keeps its shape.
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.
