In a large bowl, combine the flour, salt, and cinnamon.
Add the shortening and use a hand mixer to combine.
Add ⅓ cup water and mix to thoroughly combine.
Knead the dough in the bowl to incorporate any remaining flour.
Divide the dough into four dough balls and wrap each one in plastic wrap. Refrigerate for about 1 hour.
In a medium bowl, combine the pumpkin, sugar, cinnamon, ginger, and salt and stir well to combine. Set aside.
Divide each dough portion into four equal parts. Slap the dough balls between well floured hands until slightly flattened, and then roll them out on a lightly floured surface to about 4" wide and about ⅛" thick.
Spoon about 1 Tablespoon of filling into the center of each circle.
Fold over, pressing the edges to seal them and press with fork tines. Place them on a parchment-lined baking sheet, 1" apart.
Make an egg wash by whisking the eggs with 2 Tablespoons water in a small bowl. Brush each empanada with egg wash and sprinkle with more sugar.
Bake at 350° for 20-25 minutes or until golden brown. Remove to wire racks to cool slightly.
Serve warm with vanilla ice cream or cool completely and refrigerate, well wrapped, for up to 2 days. Frozen empanadas can be reheated in a 350° oven for 25 minutes.
