900g/2lb diced, skinned and deseeded watermelon – fiddly, but worth it
2 tbsp granulated sugar
5 tbsp lime juice (you’ll need about 3 limes)
2 tbsp grated ginger
green popping candy, to serve (optional)
Put the melon, sugar, lime juice and ginger in a blender (or use a stick blender) and whizz until smooth. skim off any fluffy stuff, then divide between ice lolly moulds and freeze overnight.
When you’re ready to serve, remove the lollies from their moulds and dip into popping candy, if you like, or see tip, before tucking in.
