Top with butter.

Bake

Cover with puff pastry and place a paper over it.
Bake in a moderate oven (350°F / 175°C) until done.

What each ingredient does

Rooks: Form the main meat of the filling, cooking through in the sealed dish.
Butter: Adds fat and richness, helping keep the meat moist as it bakes.
Puff pastry: Forms a flaky top crust that rises and browns in the oven.
