Four-Spice Ginger Cookies

This is a wonderful cookie full of warm, spices and complex flavors. The author claims the secret ingredient is white pepper but I believe that the double dose of ginger and the cardamom are what really take these over the top. I did not have orange zest but since I know lemon and ginger generally work well together I added the zest of small lemon. These cookies really spread (even after 5-6 hours in the fridge, but I did not mind. These are my new favorite cookie!
