To make the syrup, place sugar and water in a pan and heat gently while stirring until the sugar is dissolved. Add the lime zest, sliced ginger, ginger syrup and chilli to the pan and bring to the boil. Boil for about for 5 minutes.
Remove from the heat and allow to cool. Once cold, strain through a sieve into a bowl.
Prepare the fruit as directed and toss in the syrup. Chill until required. Serve sprinkled with lemon balm or mint, if desired.
