Sift flour, baking soda, cloves, cinnamon, ginger and salt into medium bowl. Combine butter, shortening and brown sugar in large bowl. Beat butter mixture until fluffy with electric mixer. Add egg, molasses and orange peel; beat until blended. Add dry ingredients; mix just until incorporated- be careful not to over-mix. Cover; chill 1 1/2 hours.
Preheat oven to 350°F.
Butter 2 baking sheets. Place 1/2 cup granulated sugar in small bowl. Using wet hands, shape dough into 12 balls. Roll balls in sugar to coat. Transfer to prepared sheets, spacing 2 1/2 inches apart. Bake until cookies are pale golden and cracked on top but still soft, about 15 minutes. Cool on sheets 1 to 2 minutes. Transfer to racks; cool completely.
