Cut lime in half, slice up ½ and juice the other half. Slice sugar cane sticks into thin strips. In a glass add the sugar, chopped lime, lime juice, mint leaves and vodka.

With a muddler, crush together all of the ingredients for about one minute, the mint and lemon will become aromatic.

Fill the glass to the brim with crushed ice then top off with seltzer water and stir thoroughly to combine the sugar, lime and vodka together with the water. Garnish with blueberries and sugar cane sticks.
