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

What each ingredient does

Brook trout
Is the main protein, cooked through while its coating browns and crisps.
Flour
Dries the fish surface so the egg and crumbs can stick evenly.
Egg
Acts as a binder that holds the cracker crumbs to the fish.
Cracker crumbs
Form a crisp, browned crust when fried.
Butter
Conducts heat for frying and adds browning and rich flavor.

The step that matters

Fry in hot butter until brown. Butter's milk solids brown quickly and can scorch at high heat, so the heat must be controlled. The coating needs enough time to set and turn golden before the fish overcooks.

Swap the parsley

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

  1. Parsleythe original
  2. Nutmegfits about as well
  3. Capersfits less well
  4. Tarragonfits less well

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