5- Wrap everything in puff pastry (if large fish use two rolls of pastry).
6- Brush with egg yolk and bake at 180°C.
7- You know the fish is cooked when the pastry is cooked and well browned (45 minutes to 1 hour depending on the size of the fish)

This delicious dish can easily be prepared the day before. Just reheat it in the oven. A nice cold Sancerre and it's amazing.
