Score dough into 8 wedges by pricking dotted lines with a fork. mark edges decoratively. Arrange rosemary sprigs decoratively on top of dough. Sprinkle dough with 1/2 tablespoon granulated sugar. Bake shortbread in middle of oven until golden brown, 20-25 minutes. Slide shortbread on parchment to a rack and cool 5 minutes. Transfer with a metal spatula to a cutting board and cut along score marks with a large heavy knife. Make another shortbread with remaining dough.
