Preheat oven to 350F

In a medium bowl mix the flour, ginger, baking soda, cinnamon, and salt until combined.

In a large mixing bowl cream the butter and shortening, then add the brown sugar and molasses and beat until light and fluffy.  Add in the eggs and stir to combine.

Add the dry ingredients into the wet ingredients in thirds stirring well to combine in between each addition.  Dough should hold together well, but be very soft.

Use a 1/4 cup measure to scoop the dough, then form into a ball and roll in the white sugar to coat.
