Press biscuit mix firmly into lined spring form tin. Place tin into fridge while preparing the cheesecake mixture.
Place cream cheese into bowl and mix 10 sec / speed 8. Scrape down and repeat.
Add condensed milk and cream and mix 10 sec / speed 7. Scrape down and repeat
Add juice and mix 15 sec / speed 4.
NB: the juice needs to be added last. The reaction of the juice will start to set your mixture almost immediately.
With a spatula scrape down and ensure all is mixed well
Immediately pour mixture on top of biscuit base, sprinkle zest on top and refrigerate for at least 3 hours. ( overnight is my preference)
When it is set, serve straight from fridge.
