1) Combine the sugar, water, ginger and vanilla pod and seeds in a small saucepan over medium heat and bring to a boil. Cook the mixture until the sugar is completely dissolved, about 1 min. Cool at room temperature and strain.
2) Combine the pineapple juice, 180g pineapple cubes, the simple syrup and vodka in a blender and blend until smooth. Pour into glasses filled with pineapple cubes, if desired, and garnish with mint and pineapple slices.
