Preheat oven to 325F. Prepare 9x5 inch loaf pan with cooking spray. Whisk 1 ¼ cups all-purpose flour, whole wheat flour, ginger, cinnamon, cloves, pepper, salt, and baking soda together in medium mixing bowl. In a separate small mixing bowl, beat together butter and sugar until fluffy. Add vanilla and egg to wet mixture. In a third small bowl, mix remaining 1 teaspoon all-purpose flour with chopped ginger. Alternate adding water and butter and sugar mixture to flour-spice mixture 1/4 cup at a time, mixing to combine. Once combined into a batter, fold in the crystallized ginger and flour mixture. Transfer to prepared loaf pan and bake for 55-60 minutes. To make the glaze whisk together confectioner's sugar, milk, lemon juice and vanilla in a medium bowl. Top gingerbread loaf with glaze and serve.
