This is a recipe that I adapted from several different recipes. I use an Israeli white cheese, which is similar in texture to a Greek-style yogurt. You can use cream cheese, if you prefer.

Instructions
Make the lemon confit:
Start by making the confit as this needs to be prepared ahead of time – the day before you want to serve it, if possible.
Take one and a half of the lemons and slice them into thin rings about 1/8 inch (3 mm) thick, discarding the end pieces and pips. Place these in a saucepan and cover with cold water, bring to a simmer for 3 minutes, then drain through a sieve and discard the water, Pour 12 fl oz (425 ml) water into the same pan, add the sugar, stir over a low heat until all the sugar dissolves, then add the lemon slices. Cook for 45 minutes, until the skin is tender.
Remove the slices with a slotted spoon. Reduce the liquid to 5 fl oz (150ml). Squeeze the juice from the remaining half lemon, add to the syrup and pour over the lemon slices. Cover and let sit overnight at room temperature.
Make the crust:
Cream the butter and sugar together for 3-4 minutes. Add flour and ground petit beurre biscuits or shortbread to the mixture and blend for 3-4 seconds until fully incorporated. Press the mixture evenly into the bottom of a 22cm (11-inch) spring-form pan.
Bake the crust at 180° for 15-20 minutes, or until golden brown. Allow the crust to cool completely.
Make the cheesecake filling:
Beat the white cheese until light and smooth. Add the mascarpone cheese and sugar and continue to beat on medium speed. Add the eggs one at a time. Add the lemon zest and juice. Pour mixture into the cooled crust.
Wrap aluminium foil around the outside of the spring-form. Place the cheesecake pan into a roasting pan, and add enough water to the roasting pan to reach halfway up sides of the cheesecake pan. Place in a 180° oven for approximately one hour or until the cake is set and the top is light brown.
Make topping while cheesecake is baking:
Let sour cream stand at room temperature 30 minutes. In a bowl whisk together sour cream, sugar and vanilla extract. Spread over entire top of cake, smoothing evenly. Bake cheesecake in middle of oven 10 minutes.
Remove the cake from the roasting pan and place on a wire rack. Allow the cake to cool slightly, and then place it in the refrigerator for 6 hours or overnight.
Before serving, decorate the top of the cake with lemon confit or plate and place on top of a slice of cheesecake.
