Add the ginger, lemongrass and cilantro to a cocktail shaker. Use a muddler to press down and twist the mixture. Repeat this a few times until the ginger releases juice.

Add the vodka, pineapple juice, agave and lime juice.

Then add ice to the shaker, then close the top and shake vigorously.

Strain the mixture into a low-ball glass filled with ice and garnish with a pineapple wedge.
