This cocktail is light, refreshing and fruity, perfect for summer sipping!
Place the ginger, 3 of the strawberries (reserve 1 for serving), salt and sugar in a cocktail shaker or jam jar, then muddle until the ginger is fragrant and the strawberries are mashed.
Add the basil leaves (reserve the sprig for later) and gently muddle just until the basil is fragrant.
Add the soju, water if using and a few big scoops of ice. Cover the cocktail shaker or jar with the lid, and shake until the outside of the container is cold.
Fill your serving glass half full with ice, then strain the drink into the cup.
Garnish with the remaining strawberry and the basil sprig, then serve.
You can use frozen strawberries, so long as you defrost them before you start making the drink.
The water is optional (I like a lighter drink, so I add it).
Make sure you use big chunks of ice. If it's too small or fine, it will melt too quickly into the drink.
