2Amalfi lemons, zest and juice, plus extra zest to serve
125g(4½oz) icing (confectioner’s) sugar, sifted
Instructions
Tip the cantuccini into a food processor and blitz them to a fine crumb. Alternatively, place them in a Ziplock bag and bash them with a rolling pin or saucepan. Set aside.
Melt the butter in a medium saucepan over a low heat, then add the blitzed cantuccini biscuits and the sugar. Cook, stirring, for 1 minute, then take the pan off the heat.
Tip the mixture into a 22cm (8½in) non-stick springform cake tin, pressing the buttery crumbled biscuits over the base to create a biscuit base. Transfer the tin to the fridge while you make the ricotta filling.
Using a hand-held electric whisk or a wooden spoon, beat together the ricotta, mascarpone, lemon zest and juice and icing (confectioner’s) sugar in a large mixing bowl for 4 minutes, until the mixture is creamy and light.
Spoon the ricotta mixture into the springform tin and spread it out into an even layer over the base. Refrigerate to set for a minimum of 3 hours, but preferably overnight, before releasing the cheesecake from the tin. Transfer it to a serving plate and top with extra lemon zest before slicing.
