Place a can coconut milk in the refrigerator overnight the day prior to making whipped cream if you plan to serve with the pie.
Pierce 2 medium sweet potatoes with a fork. Place on an aluminum foil lined pan and bake for 1 hour at 375°F. Let cool, then peel and mash with a fork or puree in a food processor. Measure 2 cups worth. (Puree can be made the day before and stored in the refrigerator until needed.)
Preheat the oven to 350°F. Make the paleo pie crust per instructions (see link above). Blind bake or partially bake for 15 minutes. (The crust can be made the day before and refrigerated raw in the pie pan overnight, then partially baked just prior to making the pie.)
Place all of the ingredients--cooked sweet potato, maple syrup, coconut milk, eggs, vanilla extract, cinnamon, nutmeg, ginger, and salt in a food processor. Blend until smooth. When measuring the coconut milk, try to get as much of the white cream as possible and less of the clear liquid.
Pour the filling into the partially baked crust. Bake pie at 350°F for 45-55 minutes. Check at 45 minutes. The center jiggle will be about the size of a quarter when it's done baking.
Remove from oven and place the pan on a cooling rack. Let cool to room temperature. Serve when cooled or place in the refrigerator for the next day. Make coconut milk whipped cream (see link above) and add a dollop to the pie.
Store pie in the refrigerator for up to 3-4 days, or in the freezer for up to 1 month. If stored in the freezer, thaw overnight in the refrigerator prior to serving.
