Grease baking sheets or spray with baking spray; heat oven to 375 F.
Combine the flour, cinnamon, salt, ginger in a bowl.
In a mixing bowl, beat sugar with eggs until well blended. Add cooled melted shortening and beat for about 1 minute longer. Beat in the molasses and the water and baking soda mixture. Stir in the flour mixture until smooth.
With a cookie scoop or tablespoon, drop onto the prepared baking sheets, leaving about 2 to 3 inches between each cookie. I baked these without chilling the dough, but the batter could be prepared a few hours in advance and chilled before baking.
Bake for 10 to 12 minutes, until set and firm.
Makes 2 to 2 1/2 dozen 2-inch to 3-inch cookies
