This is a light and refreshing cocktail that can be served as an alcoholic beverage or just as it is.
½ seedless watermelon, cut into chunks
1 tbsp. white wine vinegar
Ice cubes, gin, soda water and basil leaves, to serve
BASIL SUGAR SYRUP
110 g (½ cup) caster sugar
Handful of basil leaves
1. For the watermelon ice, place half your watermelon in a blender and blend until smooth. Strain, then pour into ice cube trays of your choice. Freeze.
2. For the basil sugar syrup combine 250 ml water and sugar in a small saucepan over medium heat and stir until sugar dissolves. Bring to the boil, then remove from the heat. Allow your syrup to sit for a few hours so the basil flavour infuses into the syrup. You can store your syrup in an air tight container or jar until required.
3. Next place your watermelon, vinegar and 60 ml basil sugar syrup in a blender and puree until smooth. Strain your liquid into a pouring jug.
4. Fill a glass, jar or even half a watermelon that has been hollowed out into a punch bowl with a few pieces of your watermelon ice. Fill a third full with your watermelon mixture, top up with soda water, gin to taste and top with fresh basil leaves.
