3¾ cups all-purpose flour
2 cups powdered sugar
¼ cup chopped crystallized ginger
1½ cups unsalted butter
2 tablespoons lemon juice
Preheat oven to 325°F. Line two baking sheets with parchment paper; set aside. In a medium bowl combine flour, 1 cup of the powdered sugar, the crystallized ginger and lemon peel. Using a pastry blender, cut in butter until mixture resembles fine crumbs and starts to cling together. Stir in 1 tablespoon of the lemon juice. Form mixture into a ball; knead until smooth.
Divide dough in half. Place each dough portion between two sheets of parchment paper or waxed paper. Roll each portion to a 12x6-inch rectangle. Cut each rectangle into thirty-six 2x1-inch pieces (72 pieces total). Place on the prepared baking sheets. If desired, prick the tops of the rectangles with a fork.
Bake for 20 to 25 minutes or until bottoms are golden brown. Transfer to a wire rack; cool.
For icing, in a small bowl combine the remaining 1 cup powdered sugar and add enough of the remaining lemon juice (1 to 2 tablespoons) to make a drizzling consistency. Drizzle shortbread with icing. Let stand until set.
