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
- Cooked fish
- Provides the main flesh and flavor of the croquettes.
- Egg
- Binds the mixture together and helps the coating adhere.
- Mashed potatoes
- Adds body and moisture so the mixture holds its shape.
- Butter
- Adds richness and a smooth, tender texture.
- Bread crumbs
- Forms a crisp outer crust that browns during frying.
The step that matters
Let the mixture cool before shaping. A warm, soft mixture is sticky and falls apart when shaped and coated. Cooling lets the starches and egg firm up so the balls hold their form through frying.
Swap the parsley
How well each one fits the dish's main ingredients (fish, egg, potato, pepper, milk, butter, bread):
- Parsleythe original
- Nutmegfits about as well
- Thymefits less well
- Cinnamonfits less well
Fit is the average pairing score against fish, egg, potato, pepper, milk, butter, bread. Candidates are from the same food group and used in at least 100 recipes.
