Firstly make the syrup. In one saucepan make simple syrup with equal measures of sugar and water, then add the halved strawberries. Simmer for 10 minutes and then strain with a fine mesh or cheesecloth. // In another saucepan, boil some water and add 5-7 stems of mint. Boil for 10 seconds then remove to an ice bath for one minute. Dry the stems with a paper towel then pick the leaves off and add to the strawberry syrup.// Blend the mixture in a blender for one minute, then strain and chill. The syrup will last for about a month in the fridge.//Now to make the mojito. Fill a highball glass with ice. Add two parts Bacardi Superior,one part lime juice and one part strawberry mint syrup into a cocktail shaker with ice and shake well. Strain into the glass and top up with the soda. Add a strawberry and mint leaf garnish and serve.
