Peel and finely grate the ginger into a large bowl, add all the remaining ingredients, chopping any larger pieces of fruit first, and mix well to combine.
Cover and pop in the fridge overnight to soak and swell.
Serve topped with fresh fruit – delicious with sliced banana, grapes and finely grated lime zest. Any leftovers will keep happily in the fridge for up to 4 days.
