4 tsp lemon juice
1/4 tbsp sugar
4 x ice cubes
2 3/4 tbsp Whiskey
Fill the Soda Siphon with cold water. Screw on 1 C02 soda charger and shake vigorously. To ensure the water is really fizzy refrigerate for 1-2 hours.
Place all the ingredients in the shaker together with some ice and shake quickly and vigorously before pouring into a tall glass with ice. Top up with a dash of soda water from the iSi Soda Siphon.
