Cut the green skin off the watermelon and cut into large chunks
Carefully cut your chilli in half, deseed and roughly chop. I highly recommend you use gloves!
Blend most of your watermelon then strain liquid.
With the last batch of watermelon add chilli, sugar and jam-set. Blend until chilli is well chopped and sugar and jam-set is dissolved. Strain liquid and add to the rest of the strained watermelon.
Juice lime and add to watermelon mix. You will need 600ml of liquid in total, if you are running short blend and strain some more watermelon.
Taste the mix and add more chilli, lime or sugar to taste
Pour into icy pole/popsicle moulds and freeze for 8 hours or overnight until set
Once set carefully remove from moulds and enjoy! Mind the drips!
