Sorry, I do not have photos of this...we enjoyed them before we had a chance to take any. They will look beautiful in a martini glass and have that pretty pinkish red color like a cosmopolitan does. Here's the recipe:
To make watermelon juice, remove the meat from the shell and put it in a food processor, blender or Vitamix. Blend until very smooth.
Pour the watermelon juice, vodka, watermelon schnapps, simple syrup, (recipe below) and lime juice into a cocktail shaker over ice. Cover, and shake until the outside of the shaker has frosted. Strain into the chilled glasses.
To make simple syrup, put equal parts of granulated sugar and water in a saucepan. Stir and bring to a boil. Boil until sugar is completely dissolved. Cool syrup. This may be stored in the refrigerator covered, for about a week.
I make several cups at a time since this is great mixed into iced tea or anywhere you want sugar to be nicely dissolved.
