Mix the biscuits with the butter in a bowl, then press into the base of the tin (but not up the sides)
Put the mascarpone, lemon curd, and lemon juice in a bowl and beat with a spatula until smooth
Spoon on to the biscuit base and level the top. Chill in the fridge for at least 4 hours and up to 24 hours to firm up
To serve, remove the cheesecake form the tin, peel off the baking parchment, and arrange on a platter. Decorate with the fruit and dust with icing sugar.
GREAT FOR A CROWD
You can make up to three cheesecakes in one go (but take care not to overbeat the mixture at step 2). If you’re making more cheesecakes than that, prepare them in separate batches.
PREPARE AHEAD
The cheesecake can be made up to the end of step 3 up to 1 day ahead. Not suitable for freezing.
