Step 1
Preheat the oven to 160°C . Grease and line the base and sides of a 9-inch (23cm) spring form cake tin. Leave an overhang of paper on the base, so it sticks out the side once the spring form tin has been assembled . This will make the cheesecake easy to remove from the base of the tin once cooked and cooled.
For The Biscuit Base
Step 2
In a small saucepan over low heat, melt the butter. Set aside to cool slightly.
Step 3
Break up the biscuits roughly with your hands and place in a food processor. Blitz until finely crumbed. Add the melted butter and blitz again until well combined and resembling damp sand.
Step 4
Tip the biscuit base mix into the lined cake tin and spread out evenly. Using a flat based glass or measuring cup, press the mix down firmly into the base of the cake tin. You want a solid foundation for the cake to sit on.
For The Filling
Step 5
Wipe out the food processor bowl so it is free of crumbs. Put the cream cheese, sugar and salt into the food processor and blitz for 1 minute until well combined and looking creamy. Add the ricotta and greek yoghurt and blitz again for about 2 minutes until smooth.
Step 6
Crack the eggs in one at a time, blitzing for about 30 seconds to combine each one before adding the next.
Step 7
Zest the lemons directly into the food processor bowl, then blitz for 30 seconds until combined. The mixture will be a thick and creamy liquid.
Step 8
Pour the filling on top of the biscuit base in the cake tin and smooth the top with a spatula. Place on the lowest rack in the oven and bake for 50-60 minutes, until set, the edges with be light golden brown on the sides and still a little jiggly in the middle.
Step 9
Turn off the oven, but leave the cheesecake in the oven with the door ajar. Let it cool completely in the oven. This will help prevent the surface from cracking as it cools. Once completely cool, place it in the fridge for at least 4 hours, up to overnight, to firm up.
Step 10
When ready to serve, transfer from the cake tin to a large plate or cake stand, top with fresh berries or a blueberry compote if you like, and slice to serve.
