Duchy salmon and spinach plate pie

Melt the butter in a non-stick pan, add the flour and cook for a minute. Off the heat, add a little milk and stir until smooth. Gradually add the rest of the milk, stirring. Simmer for 5 minutes. Season, add the nutmeg and stir in the caper paste. Leave to cool.

2. Preheat the oven to 200ºC, gas mark 6. Cook the eggs in boiling water for 8 minutes, drain and run under cold water. Shell and chop coarsely. Blanch the spinach in a little water for a minute until wilted then drain thoroughly. Roll out one block of the pastry and use to line a 23cm deep pie plate. Scatter over the salmon, the hard-boiled eggs and the spinach and pour over the sauce. Roll out the remaining pastry and use to top the pie. Trim the edges and pinch together. Make two steam holes in the centre. Chill for 15 minutes.
