Notes
To make 1/2 cup simple syrup, boil 1/2 cup water and add 1/2 cup granulated white sugar. Turn heat to simmer and stir until dissolved. Turn off the heat and let cool. Now it's simple syrup!
Use fresh fruit for this recipe. Frozen just won't be great.
To make star-shaped pineapple pieces, cut long & wide pieces of pineapple off the side of the fresh fruit. use a star cutter to cut shapes.
