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

What each ingredient does

Trout
Forms the main body of the dish, cooking through to a moist, flaky texture.
Flour
Forms a thin coating that helps the outside brown and crisp during frying.
Plain melted butter
Adds richness and fat to balance the lean fish when served.

The step that matters

Fry the trout until nicely browned and cooked through. Fish cooks quickly, so overcooking dries the flesh while undercooking leaves it unsafe. Turning gently lets both sides brown evenly and the heat reach the thickest part of the fish.

Swap the parsley

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

  1. Jalapenofits better
  2. Capersfits better
  3. Nutmegfits better
  4. Parsleythe original

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