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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Silver fish
- Provides the main body and flavor of the balls.
- Egg
- Binds the fish mixture so the balls hold their shape.
- Penny roll
- Absorbs milk and adds softness, helping the mixture stay moist.
- Milk
- Softens the soaked roll and adds moisture to the mixture.
- Bread crumbs
- Form a crisp, golden coating during frying.
The step that matters
Squeeze the roll dry. Excess milk left in the soaked bread makes the mixture too wet to bind, so the balls may fall apart or steam rather than hold their shape and brown well.
Swap the onion
How well each one fits the dish's main ingredients (fish, milk, egg, parsley, pepper, bread):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against fish, milk, egg, parsley, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
