Preheat the oven to 180 C and spray a 23 cm loose bottomed tin with non stick spray.
Mix the biscuits and butter and press into the bottom of the prepared cake tin.
Beat the eggs and sugar together until light and creamy. Add the lemon juice while beating.
Add the cottage cheese, cream and cake flour, mix well and turn the mixture into the prepared cake tin.
Bake for 10 minutes at 180 C, reduce the oven temperature to 140 C and bake for another hour until the filling is firm but still slightly creamy in the centre.
Switch off the oven, but leave the cheesecake to cool in the oven.
Remove from the cake tin when cold and transfer to a serving platter.
