Step 1

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.

Step 2

Add the basil leaves (reserve the sprig for later) and gently muddle just until the basil is fragrant.

Step 3

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.

Step 4

Fill your serving glass half full with ice, then strain the drink into the cup.

Step 5

Garnish with the remaining strawberry and the basil sprig, then serve.
