Bring all ingredients to room temperature. Heat oven to 325 degrees F.
Mix the flour and baking soda in a bowl and set aside.
Use an electric mixer to mix the two sugars and shortening. When creamy add the
vanilla extract, salt and egg white. Add the flour 1/2 cup at a time, adding a tablespoon
of warm water as necessary to mix the flour - don't exceed 4 tablespoons of
water - this will make a firm dough. Mix in chocolate chips. As the dough gets thicker
you may want to mix by hand. Roll into 2-inch balls and press down with the palm
of the hand to flatten.
