What each ingredient does

Butter
Forms the rich base of the sauce and carries flavor through the fish.
Flour
Thickens the butter and water into a light sauce that clings to the fish.
Cooked fish
Provides the main body of the dish, gently reheated in the sauce.
Lemon juice or chili vinegar
Adds acidity that brightens the rich butter sauce when added at the end.

The step that matters

Heat the fish slowly in the sauce. Cooked fish turns dry and tough when overheated. Gentle heat warms it through while keeping its moist, flaky texture and lets the sauce thicken evenly.
