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 and gives it its delicate flesh.
Butter
Adds richness and fat to the sauce, carrying flavour and smoothness.
Flour
Thickens the cooking liquid into a body for the sauce.
Eggs
Thicken the sauce as they set with gentle heat, giving it a creamy texture.

The step that matters

Adding the eggs to the sauce. Egg proteins set with heat, so the sauce can curdle or turn grainy if the eggs are added to a boiling sauce or stirred too little. Pour slowly while stirring and keep the heat moderate so the sauce thickens smoothly.
