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
- Provide the bulk of the balls and set firm when cooked.
- Raw egg yolk
- Binds the mashed yolks and adds richness to hold the balls together.
- Flour
- Absorbs moisture and helps the mixture hold its shape.
The step that matters
Forming the balls. The raw yolk and flour are the only binders holding the mashed yolks together. If the mixture is too wet or poorly bound, the balls can crumble when they hit the simmering 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.
