Why it works: Flour and parsley are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 16,675 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Fried Perch
Ingredients
Directions
Prepare
Wash and scale the perch, then wipe them dry.
Lightly dust the fish with flour and rub off the excess.
Dip the fish into the beaten egg, then coat with bread crumbs.

Drain on an inverted sieve for a few minutes.
Serve on a hot dish garnished with parsley.
Serve shrimp sauce, anchovy sauce, or melted butter in a tureen.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and egg 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
- Perch
- The main fish, which cooks through in the hot fat while its coating crisps.
- Flour
- A thin dry layer that helps the egg wash cling to the fish.
- Egg
- A binding wash that holds the bread crumbs to the fish surface.
- Bread crumbs
- Form a crisp, golden browned crust when fried.
The step that matters
Frying in plenty of hot fat. Enough boiling fat keeps its temperature high when the cold fish goes in, so the coating crisps and browns quickly instead of soaking up grease. Crowding or cool fat leads to greasy, pale results.
Swap the parsley
How well each one fits the dish's main ingredients (flour, egg, bread, shrimp):
- Capersfits better
- Nutmegfits about as well
- Turmericfits about as well
- Parsleythe original
Fit is the average pairing score against flour, egg, bread, shrimp. Candidates are from the same food group and used in at least 100 recipes.
