Five-Spice Duck with Butternut Squash Ravioli and Broccoli Rabe

Boil plum wine in heavy medium saucepan until syrupy and reduced to generous 1/3 cup, about 16 minutes. (Can be made 1 day ahead. Let stand at room temperature. Rewarm over low heat before using.) Using heavy large knife, cut each duck lengthwise in half. Cut away backbone. Cut off leg-thigh pieces, then cut off breast pieces; trim excess fat. Remove bones from breast pieces. Transfer leg-thigh pieces and breast pieces to platter (reserve remaining duck trimmings for another use). Preheat oven to 375 °F. Mix Chinese five-spice powder, salt, ground black pepper, and ground ginger in small bowl. Rub spice mixture all over duck pieces. Heat olive oil in heavy large ovenproof skillet over medium-high heat. Add leg-thigh pieces and cook until deep brown, about 4 minutes per side. Cover skillet and roast duck in oven until cooked through, about 45 minutes. Transfer duck to plate; cover with foil to keep warm. Heat same skillet over medium-high heat. Add duck breasts to skillet; cook to desired doneness, about 10 minutes per side for medium.
