4cups roughly chopped cucumber (can leave the seeds/peel on)
1/2cup fresh lime juice
1/3cup packed mint leaves
1/4cup sugar (I usually start with 1/4 cup and add more if needed)
4 1/2cups water
Place all ingredients in a high powered blender and puree until smooth. Depending on the size of your blender, you may need to do this in batches. I usually puree the cucumber and lime juice first, then add in the rest to make sure it all fits. If drinking immediately, blend in a few handfuls of ice to the blender before straining.
Strain using a fine mesh strainer or nut-milk bag (this fine mesh strainer over a large mason jar works perfectly).
Serve over lots of ice or store in the fridge until ready to drink.
