The filling consists of, 4 1/2 oz of semisweet dark chocolate, broken into pieces, 1 cup ricotta cheese, 1/3 cup confectioners sugar, 2 tbsp dark rum, finely grated rind of half an orange, 1 tsp vanilla extract, 1/2 cup finely chopped walnuts.
If you're adventurous you can make your own double pie crust or just buy a good quality one like I did.
Melt the chocolate in a heatproof bowl over a pan of hot water. Mix together the ricotta, confectioners sugar, grated orange rind, rum, vanilla and walnuts, mixing evenly. Roll out dough to fit into a 9" tart pan with removable bottom. Spoon the ricotta mixture evenly into the pastry, it will be thick, don't worry. Roll the remaining dough and cut into strips to form a lattice top. Place on a baking sheet in a preheated 350F oven for 35-40 minutes, until firm and golden.
ENJOY!
ENJOY!
