New York style Cheesecake
FOR THE CRUST
- 85ml butter melted, plus extra for tin
- 140g digestive biscuits, made into fine crumbs
- 1 tbsp sugar, granulated or caster
FOR THE CHEESECAKE FILLING
- 3 x 300g pack full fat soft cheese
- 250g caster sugar
- 3 tbsp plain flour
- 1½tsp vanilla extract
- finely grated zest of 1 lemon
- 1½tsp lemon juice
- 3 large eggs, plus 1 yolk
- 284ml carton soured cream
FOR THE SOURED CREAM TOPPING
- 142ml carton soured cream
- 1 tbsp caster sugar
- 2 tsp lemon juice
Plus 2 hours cooling & several hours chilling
- Position an oven shelf in the middle of the oven. Preheat the oven to fan 160C/conventional 180C/gas 4. Line the base of a 23cm springform cake tin with parchment paper. For the crust, melt the butter in a medium pan. Stir in the biscuit crumbs and sugar so the mixture is evenly moistened. Press the mixture into the bottom of the pan and bake for 10 minutes. Cool on a wire rack while preparing the filling.
- For the filling, increase the oven temperature to fan 200C/conventional 240C/gas 9. Beat the soft cheese until creamy, about 2 minute, gradually add the sugar, then the flour and a pinch of salt.
- Continue by adding the vanilla, lemon zest and juice. Whisk in the eggs and yolk, one at a time. Stir the 284ml carton of soured cream until smooth, then measure 200ml/7fl oz (just over ¾ of the carton). Whisk to blend, but don't over-beat. The batter should be smooth, light and somewhat airy. You can use a mixer for this.
- Brush the sides of the springform tin with melted butter and put on a baking sheet. Pour in the filling - if there are any lumps, sink them using a knife - the top should be as smooth as possible. Bake for 10 minutes. Reduce oven temperature to fan 90C/conventional 110C/gas ¼ and bake for 25 minutes more. If you gently shake the tin, the filling should have a slight wobble. Turn off the oven and open the oven door for a cheesecake that's creamy in the centre, or leave it closed if you prefer a drier texture. Let cool in the oven for 2 hours. The cheesecake may get a slight crack on top as it cools.
- Combine the reserved soured cream with the 142ml carton, the sugar and lemon juice for the topping. Spread over the cheesecake right to the edges. Cover loosely with foil and refrigerate for at least 8 hours or overnight.
- Run a round-bladed knife around the sides of the tin to loosen any stuck edges. Unlock the side, slide the cheesecake off the bottom of the tin onto a plate, then slide the parchment paper out from underneath.
