Course Drinks
Prep Time 7 minutes
Servings 11 cups


  • 1 cucumber long, washed
  • 3 sprigs fresh mint washed and bruised
  • 1/2 lemon juiced
  • 11 cups water (filtered or mineral), or aloe water cooled; around 2.6 litres


  1. Firstly, when selecting a cucumber, go for a long one without any wrinkles or any nasty sponge-like spots. Wash it properly and cut the stems off.

  2. Carefully peel the cucumber vertically - from one end to the other. Don’t throw away the skin! Keep it to decorate your drinks for additional sliminess.

  3. The aim is to get long, super-thin ribbons. Continue peeling until you get to the seeds - then stop and move to the opposite side of the cucumber. You can throw away the seeds, or better yet - eat them! 

  4. Place the sliced cucumber, mint, and juice of ½ lemon in a large jug. Next, pour water into it. Cover and place in the refrigerator for a minimum of 1 hour. The longer you infuse it, the stronger the flavor will become.

  5. Pour into glasses and serve with slices of cucumber for garnish.

Recipe Notes

You can add slices of lemon instead of juicing it - just remember to remove the slices after a few hours from your Gillywater. Otherwise the beverage will become too sour.
