Clean the strawberries, ginger root, and chilli pepper, then cut them into small pieces and juice the lime.
Add the strawberries, ginger root, chilli pepper, lime juice, rum (or soda water for alcohol-free), and sugar to a blender. Puree for 1-2 minutes until smooth.
Divide the puree between 2 glasses, fill with crushed ice, garnish with a few mint leaves, and serve immediately.
