Wash and slice your apples into thin slivers.
In a large jar you will add your sliced apples, cinnamon stick, star anise, cardamom pod, cloves, nutmeg and ginger. Pour your vodka over the mixture.
Cover and place the vodka mixture in the fridge for 48 hours. Try to shake it a few times in between.
Then after the 48 hours you will add your 1/2 cup water and granulated sugar in a saucepan and stir until dissolved on medium heat.
Strain your vodka with a fine mesh strainer or cheese cloth as your sugar water is cooking. Remove all spices and apples from the vodka.
Bring to a simmer and let cook for 30 seconds, then remove from heat and allow to cool.
Add the 1/2 cup of the simple syrup you made and pour into the infused vodka, along with vanilla extract.
Stir well, and then store in a glass container for up to 2 weeks.
