Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Trout
The main ingredient, whose flesh becomes moist and flaky while the skin crisps in hot fat.
Flour
Dries the fish surface and forms a light coating that browns and crisps when fried.
Boiling fat or oil
Conducts heat quickly to cook the fish and brown its coating.
Melted butter
Adds richness and fat flavour to the finished fish.

The step that matters

Fry in fat that is already boiling. Hot fat seals the flour coating almost at once, so the crust browns and crisps instead of soaking up grease. Fat that is not hot enough lets the coating absorb oil and stick to the pan.

Swap the parsley

How well each one fits the dish's main ingredients (flour, butter, egg, bread):

  1. Nutmegfits better
  2. Capersfits better
  3. Parsleythe original
  4. Cinnamonfits about as well

Fit is the average pairing score against flour, butter, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
