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

What each ingredient does

Brook trout
The main protein, cooked whole by pan-frying in hot butter.
Flour
Forms a thin dry coating that browns in the hot butter and helps the crust form.
Butter
Hot fat that fries the fish, adding browning and a rich flavour.

The step that matters

Remove the fish as soon as it is done. Fish protein sets quickly and dries out with extra heat, so leaving it in the hot butter past doneness makes the flesh tough and dry.

Swap the lemon

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

  1. Raisinfits better
  2. Vanillafits better
  3. Coconutfits better

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