New Zealand Fish Pie

Melt butter in a saucepan. Add onion and cook until clear. Stir in curry powder. Cook for 30 seconds. Stir in flour and cook until frothy.

Gradually add milk, stirring constantly until mixture boils and thickens. Remove from heat. Add fish and pepper to taste. Stir and set aside until cool.

Place one sheet of pastry in a pie tin. Spread fish mixture over pastry and then dampen edges of pastry with a little water. Carefully top with the second sheet of pastry, make a few escape holes on top crust, and crimp the edges together in your favorite design. Lightly beat egg yolk and brush top surface of pie.

Bake at 425 degrees F for approximately 20 minutes or until crust is golden yellow.
