1) Remove the honeydew and cantaloupe seeds and rind before blending until liquefied. Pour this concoction into a shaker glass filled with ice and melon vodka. Shake for approximately 6 seconds then strain into a large chilled martini glass.
2) Garnish by skewering the three melon balls on a swizzle stick with the honeydew ball in the centre.
Cook's Note: If you like your martinis a bit sweeter, add 1 teaspoon agave nectar along with the melon vodka.
