Finish your meal with this impressive dessert, with billowing cream and fresh summer fruit
Whisk the egg whites just until they form stiff peaks. Gradually whisk in the sugar, a couple of tbsp at a time, making sure you whisk really well between each addition. When all the sugar has been added, keep whisking for a couple of mins until the mixture is really thick and glossy and looks a little like shaving foam. Carefully stir in the cornflour, vinegar, cocoa powder and chocolate with a large metal spoon, just until incorporated.
Tear off a sheet of baking parchment and use to cover a baking sheet. Mark a 25cm circle on the paper. Spoon over the meringue mixture, swirling into the circle, building up the sides a little, ready to keep the filling in. Cook for 1½ hrs. Leave to cool.
When ready to serve, whip the double cream and icing sugar together in a big bowl until soft peaks form. Spoon the cherry compote over the meringue, dollop over the cream, then swirl around. Arrange a few of the fresh cherries on top to finish.
