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

What each ingredient does

Trout
Is the main protein, cooked gently in salted water so it stays moist and tender.
Milk
Forms the base of the dressing, carrying the flavour and helping it become a smooth sauce.
Flour
Thickens the milk into a smooth, lightly bound dressing and coats the cloth around the fish.
Egg
Enriches the dressing and sets with gentle heat, adding body and richness.
Butter
Adds richness and fat to the finished dressing, giving a silkier mouthfeel.

The step that matters

Stirring the egg into the thickened milk. If the milk is too hot when the beaten egg goes in, the egg can scramble into lumps instead of enriching the dressing smoothly. Adding it gradually and keeping heat moderate lets it thicken evenly.
