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 that is cooked and served whole.
Butter
Fries the fish, adding richness and promoting golden browning in the pan.
Flour
Forms a light coating that browns crisply and helps seal in moisture during frying.

The step that matters

Frying until golden brown. The fish must be fried in hot butter long enough to brown, which gives crisp flavor, but not so long that it dries out. Adding fish to properly heated butter helps the flour coating set quickly so it does not absorb excess fat or stick to the pan.
