Begin by bringing the sugar and water to a rolling boil then set aside to cool.
Mix the pumpkin puree into the water and sugar mixture. I typically whisk this in.
Then, pour this into the ice cream maker compartment of your particular ice cream maker and add in the seasonings and vanilla. Add enough 1/2 and 1/2 to bring the mixture up to the fill line on your maker.
Follow the remaining instructions per your ice cream maker.
