SOUR CHERRY AND LEMON ICE-BOX CAKE

Steps:

• Lightly grease the baking tin and line the base with parchment paper. If you want to remove the cake from the tin to serve, you can line the tin with a piece of parchment paper that overhangs the two long sides.
• For the cherry compote, place the cherries, kirsch, sugar and lemon juice into a large saucepan and cook over a medium-high heat for about 5 minutes, until the fruit softens and releases a lot of juice. Use a slotted spoon to remove the cherries to a heatproof bowl, leaving the syrup in the pan. Continue cooking the syrup until it is reduced to about 240 ml (8½ fl oz / 1 cup).
• Place the cornflour in a small bowl and whisk in a little of the cherry syrup to form a smooth paste. Add this to the cherry syrup in the pan and simmer, stirring, for a couple of minutes, or until slightly thickened. Pour the syrup over the fruit, cool slightly, then cover with clingfilm and refrigerate until cool.
• For the filling, whisk together the mascarpone, icing sugar, 600 ml (20 fl oz / 2½ cups) of the cream and the vanilla in a bowl until the mixture just starts to hold its shape. Add the lemon curd and continue whisking until the mixture holds soft peaks.
• To assemble the dessert, spread a thin layer of the lemon cream over the base of the prepared tin, then cover with a layer of biscuits, breaking them up as needed. Spread over half of the remaining lemon cream and then dollop over about a third of the cherry compote. Repeat the layering a second time and then finish with a final layer of biscuits.
• Cover the tin with clingfilm and refrigerate or freeze for at least 4 hours before serving.
• Just before serving, whip the remaining cream to soft peaks and spread over the dessert. Cut into slices and serve each portion with a spoonful of the remaining compote.
• Store in a sealed container in the freezer for up to 2 weeks; if refrigerated, it will keep for 3-4 days.
