1/2 cup water
1/2 cup peeled and chopped fresh ginger
1 ripe pineapple cut into chunks
1 large mango pited, peeled and cut into chunks
Juice and zest of 1 lime
2 tablespoons white rum
2 tablespoons chopped mint leaves
Place sugar, water and ginger in a small saucepan and bring to a boil. Reduce heat to a simmer & cook until liquid is clear and thickened slightly, about 5 minutes.
Remove from heat and let cool completely. Strain syrup through a fine-meshed sieve, pressing down on ginger to extract all flavor & syrup. Discard ginger.
Place pineapple, mango, ¼ cup of the ginger syrup, lime juice and zest, rum and mint in a bowl and toss to combine. If desired, chill before serving.
