Stir together the flour, cinnamon, ginger and salt. If you have a KitchenAid stand mixer, you can mix this up in that bowl.
In a small saucepan, combine the corn syrup, sugar and butter. Heat over medium heat, stirring constantly, until the butter is melted and everything is blended.
Pour the warm mixture into the flour mixture and mix until blended. If you don't have a stand mixer, you can mix this by hand.
Refrigerate the dough about an hour to cool it off.
Roll the dough out on parchment paper to a thickness of 1/8".
Cut your pieces and bake 12-15 minutes at 350F.
Check for air bubbles while baking and poke them with a sharp knife or fork so the pieces stay flat.
