What each ingredient does
- Trout
- The main ingredient; heat sets its proteins, firming the flesh so it flakes.
- Melted butter
- Adds fat and richness, and carries the cayenne flavour through the sauce.
- Cayenne pepper
- Adds a sharp, mild heat that contrasts with the rich butter.
The step that matters
Boil the trout rapidly for the right time. Heat quickly sets the fish proteins, and overcooking squeezes out moisture and makes the flesh dry and tough. Larger fish need more time, so timing should follow their size.
