Twice-Baked Sweet Potatoes
["6 large sweet potatoes (3 1/2 to 4 lb.)", "1/4 c. orange juice", "6 Tbsp. cold butter or margarine, divided", "1/4 c. all-purpose flour", "1/4 c. packed brown sugar", "1/4 tsp. ground cinnamon", "1/4 tsp. ground ginger", "1/8 tsp. ground mace", "1/4 c. chopped pecans"]
["Pierce potatoes with a fork. Bake at 375\u00b0 for 40 to 60 minutes or until tender. Allow potatoes to cool to the touch. Cut them in half lengthwise; carefully scoop out pulp, leaving a 1/4-inch shell. Place pulp in a large bowl. Add orange juice. Melt 3 tablespoons butter; add to pulp and beat until smooth. Stuff the potato shells; place in an ungreased 15 x 10 x 1-inch baking pan."]
