Though you can use any sweet biscuit, I used Milk Arrowroot Biscuits. I think this is my favourite part of making the Cheesecake as you feel like a kid in a sandbox again.
After your shell cooks, you can pour in your cream cheese mixture (cream cheese, lemon zest, sugar, eggs, sour cream and lemon juice). This is then baked for one and half hours, before you cool it and pour on a sour cream layer (sour cream, sugar and lemon juice). This topping is then baked for additional 20 minutes, before you leave it to cool in the oven with the door ajar. I recommend leaving the cheesecake overnight as I feel three hours doesn't give it adequate time to set.
New York Cheesecake in its full glory!
