Puff Pastry: Apple Tart with Mascarpone Cheese

Based on a recipe from here

with the following tweaks:

Thaw the puff pastry to room temp. Cut the apple into thin slices and add jaggery to them (instead of brown sugar, am I a baker here?) and let it rest for a while. Then arrange the apple pieces on the puff pastry sheets and sprinkle sugar over it. Put it in the oven and bake for about 15-18 minutes. 

Meanwhile take a dollop of mascarpone cheese and add some lemon juice + 3/4 tsp of sugar. Whip this till you get a creamy light mixture. 

Spread this over the puff pastry once it is done, and serve.
