First off, you'll need 1 15-oz. can pumpkin purée, 1/4 tsp. salt, 1 1/2 tsp. cinnamon, 1/2 tsp. nutmeg, 1/2 tsp. ginger, 1 14-oz. can of sweetened condensed milk, 2 large eggs, 1 double pie crust, and 1/2 c. thick caramel sauce. Whisk the pumpkin puree, salt, spices and condensed milk in a saucepan on medium heat. Then let it cool before whisking the eggs in. Then place your store-bought pie crust into an 8' pie plate and pour the pumpkin filling. You can spoon the caramel sauce on top until it looks marbled. Then cover the pie with the crust and use a toothpick and a knife to sketch and carve out Jack Skellington's face and bake for 15 minutes at 450 degrees F. Then reduce the temp to 350, cover the top with aluminum foil and bake for another 40 minutes. Then let it cool and serve.
