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
- Tench
- The fish is the main ingredient, providing the flesh that is cooked and served.
- Eggs
- Beaten eggs bind the bread crumbs to the fish so the coating adheres during frying.
- Bread crumbs
- Crumbs form a crisp, golden coating that browns and protects the fish while it fries.
- Vinegar
- Acidity in the marinade gently flavours the fish and helps firm its surface.
The step that matters
Fry the fish until golden brown. Frying in hot fat browns the breadcrumb coating through the Maillard reaction and sets the egg, so the crust turns crisp. If the fat is not hot enough, the coating absorbs oil and becomes greasy and can fall off.
Swap the onion
How well each one fits the dish's main ingredients (vinegar, pepper, parsley, egg, bread):

- Onionthe original
Fit is the average pairing score against vinegar, pepper, parsley, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
