In a shaker, combine the drink ingredients. Fill with ice and shake vigorously for 15 seconds. Pour the contents of the shaker (including the ice) into a glass. To garnish, press the pineapple slice into the dried blue coconut flakes and perch it on the rim of the glass.
Co-CuraçaoIn a small bowl, combine the blue curaçao and coconut. Stir and let sit for 30 minutes. Strain the liquid through a fine-mesh strainer into an airtight container, reserving the coconut flakes. Spread out the soaked coconut flakes on a sheet pan and let dry for about 5 hours. Store the infused blue curaçao and the coconut flakes in separate airtight containers in a cool, dry place for up to 3 weeks.
