First you need to make the crust. Preheat the oven to 350 F. Butter a 10 inch pie platter. In a food processor pulse the crackers and peanuts until finely combine. Press the crumb mixture into the bottom and the side of the pie dish. Bake for about 10-12 minutes. Then cool on a rack. Meanwhile, using a microwave, melt the chocolate until smooth and uniform. Spread evenly in the pie crust; set aside until the chocolate sets, 10-15 minutes. For the filling, beat the peanut butter, mascarpone, vanilla extract and milk with a mixer, until smooth. Add the confectioners sugar and mix until incorporate. In a medium bowl beat the heavy cream until soft peaks. Gently fold half of the whipped cream into the peanut mixture until combine, then follow the rest. Spoon into the prepared dust and smooth the top. Cover with plastic wrap and refrigerate for at least 4 hours, or overnight. And the last step is making the meringue. Fill a medium saucepan one quarter full with water. Set the saucepan over medium heat, and bring to a simmer. In a medium metal bowl combine egg whites, sugar, and salt. Place the bowl over a pot of simmering water to form a double boiler. Whisk constantly until sugar is dissolved, about 3-4 minutes. Whisk the eggs with an electric mixer, until the meringue is thick and glossy, about 8-10 minutes. Using a piping bag pipe the meringue on top of the pie. Lightly toast with the torch.

First you need to cook the pie crust. Pulse all the ingredients for the crust in a food processor, until it starts to form a ball. Turn off the processor and knead the dough with your hands, until a smooth. Wrap it into a plastic food wrap and then put it in the refrigerator for a half an hour. Preheat oven to 375 F. Roll out pastry to 1/8 inch thick (3mm), and line a 9- or 10-inch tart pan. Pierce the crust with a fork for a couple times. Line pastry with parchment paper, fill the paper with a little raw beans or rice, and bake in preheated oven for 15 minutes. Remove parchment and rice, grease the pie with lightly beaten egg.  Continue baking another 5 min. Lower the oven heat to 305 F. In a mixing bowl, mix together all the ingredient for filling, but do not over beat. Pour the mixture through a strainer. Place the tart pan on a baking sheet, and carefully pour the lemon mixture into the baked pastry crust. Bake for about 30-40 min until the tart is nearly set. The filling will be runny in the center, and will set when cool. Sprinkle with a confectioners sugar when serve.
