Combine all ingredients, besides the edible flower, in a cocktail shaker
Add ice and shake vigorously for 10-15 seconds
Strain over ice in a tall wide glass (or wine glass) and garnish with watermelon and a beautiful edible flower of your choosing
Must use brined feta cheese. Fine strain the brine out of a high-quality feta cheese box before you use it in the cocktail.
Potato vodka has a slightly thicker texture that will work better with the watermelon and the brine.
If you don't have a fruit juicer, cut the watermelon into 2 inches cubes and muddle it before adding the rest of the ingredients in the shaker. (Use 4-5 Cubes to get about 3 ounces)
