175ml freshly squeezed lime juice (6–10 limes)
1 x 700ml bottle of Bertha’s Revenge Irish Gin
100ml water
2 tablespoons caster sugar
ice cubes
1.5 litres sparkling water
lime wheels, to garnish
- 1. Pour juice into a large jug, then add the gin, water and sugar. Using a hand blender, blitz it for 30 seconds. Pour into a clean 1-litre swing-top bottle. Label with the name and date and stick it in your fridge door to chill.
- 2. For each serve, give the bottle a quick shake. Fill a slim jim or long glass with ice, pour in 70ml of the gin mix and top it up with sparkling water. Garnish with a lime wheel.
- 3. This will keep for two weeks in your fridge. After you’ve opened it use it within a couple of days, as the lime will start to fade.
