: Prepare the pie dough as directed in the Basic recipe, adding the chocolate along with the flour. Roll dough out on lightly floured parchment paper to a 12-inch (30.5 cm) round and about 1/4 inch (6 mm) thick. Fit into prepared pie plate, trim edges, fold edges under and crimp decoratively. Line crust with aluminum foil and fill with pie weights. (You can read more about Blind Baking
