I substituted brown rice syrup for half the sugar.
Makes 1 quart.
1 cup water
1 cup sugar
5 ounces bittersweet chocolate, coarsely chopped
2 cups canned coconut milk
1 tablespoon dark rum
Heat water and sugar in a medium saucepan until sugar is dissolved. Add chocolate to the syrup and stir until chocolate is completely melted. Remove from heat, and stir in coconut milk and rum.
Chill completely
