How to Make It
In a small saucepan, combine the sugar with the water and bring to simmer, stirring until the sugar is dissolved. Transfer the syrup to a blender and let cool. Add the mangoes, lemon juice and ginger and puree until smooth.
Freeze the mixture in an ice cream maker according to the manufacturer's instructions. Transfer the sorbet to a plastic container and press a piece of plastic wrap directly onto the surface. Freeze for at least 1 hour, until firm. Scoop into bowls and serve.
