Preheat oven to 375 degrees F.
Using an electric mixer, cream together the sugars, butter, and zest, until fluffy. Add the orange juice and blend in. Mix in one egg at a time, mixing well after each egg.
Sift together the flour, soda, ginger, and salt add to the butter sugar mixture and beat until well blended.
Place the 2 tablespoons of sugar and orange juice in separate bowls and set aside.
Roll the cookies into small balls, about the size of a walnut. First dip the top of the cookie into the orange juice and then into the sugar. Place on a ungreased cookie sheet with the sugar side facing up.
Place in a preheated oven and bake for about 10 minutes or until edges of cookies are lightly browned. Take out of oven and place the cookie sheet on a cooling rack for a few minutes. Remove the cookies from the cookie sheet and place on the cooling rack and continue to cool until completely cooled. Store in an air tight container.
