½ cucumber, peeled and diced
4 limes, halved and juiced, spent skins reserved
50g caster sugar
500ml coconut water
1 generous handful mint leaves
Make this just before serving, because it should be fresher than Mae West after a couple of gins. While you can use bottled lime juice in other drinks, the oils from the fresh lime skins are crucial to mojitos of any kind.
From Mark Diacono
In a large jug, use a stick blender to reduce the cucumber, lime juice and sugar to juice, then stir in the coconut water. Divide the lime skins and mint between four glasses, then use a wooden spoon to muddle (ie, semi-enthusiastically encourage) the flavours and scent from both. Add a good handful of crushed ice to each glass, fill with the cucumber-coconut water and serve.
