For the meringue
- 3 egg white (left over from the fish pies, see 'Goes well with', below)
- 175g caster sugar
- ½ tsp mixed spice
For the prunes and cream
- 2 tbsp instant coffee
- 50g caster sugar
- 250g pack ready-to-eat pitted prune
- 285ml and 142ml pot double cream
Heat oven to 150C/fan 130C/gas 2 and line 2 baking sheets with baking parchment. Put the egg whites in a clean bowl and beat with an electric whisk until thickened and frothy. While whisking, add sugar 1 tbsp at a time until the mix is stiff and glossy. Fold in the spice.
Working quickly, pile 8 big spoonfuls of the meringue onto the baking sheets, spacing them evenly apart. Then, with the back of a spoon, lightly flatten them and hollow out the centres to make nest shapes. Bake for 45 mins, then turn off the oven and leave the meringues inside to cool for 4 hrs or overnight. Can be made 2 days ahead and kept in an airtight container.
Put the coffee and sugar in a pan with 200ml water. Add the prunes, bring to a simmer, then stir to dissolve the coffee. Leave to simmer for 10 mins until most of the liquid is absorbed, then take off the heat and cool. Can be made 2 days ahead and chilled.
To serve, whip the cream until it holds its shape. Spoon onto the meringues, then top with the prunes and a little of their juice.
