4 tsp Agave syrup
Thinly slice the cucumber and add the slices to a large pitcher of water with a large sprig of mint and a sprig of cilantro. Allow the flavors to infuse for at least an hour. This will become the base for the drink. Heat the limes, sliced in half, in the microwave for 30 seconds. Squeeze the juice from the limes into a cocktail shaker. Add the agave syrup or a sugar syrup to the lime juice, ice cubes and 1 cup of the cucumber infused water. Shake vigorously and pour into glass. Garnish with a sprig of mint.
