Add sugar and juice from lemon to martini shaker.

Swirl this combination around a bit in the cocktail shaker so the sugar has a chance to dissolve before adding the rest of the ingredients.

Now add the water, mint, ice cubes and vodka (if using).

Cap it off and shake enough to really beat up the mint ... that’s how the magical flavor is released.

Pour into your favorite martini glass, garnish and enjoy!
