For Tequila Sunrise on a stick, cut the pineapple into small pieces and puree (coarsely or very finely, depending on your taste).
Pour tequila, pineapple puree and juice into a blender and blend vigorously.
Place a teaspoon of raspberry syrup in each of the small, freezer-safe ramekins, carefully fill with the pineapple mix and insert a shish kebab skewer into each as a stem.
Place the ramekins in the freezer and freeze Tequila Sunrise on a stick for at least six hours.
