This pie contains the flavors of the Italian confection panforte: honey, nuts, and candied citrus. It's slightly reminiscent of holiday fruitcake. Use the 9-inch pie pastry (double the recipe), or buy a refrigerated pastry (15-oz. package; use at room temperature). Follow steps 4 and 5 of pastry recipe to roll half the dough for bottom crust and to line pan (don't fold or flute edge). If making pie up to 2 days ahead, cover airtight and store at room temperature.
