If you follow me on instagram, and you should. 😉 you may have noticed a couple of Juicy Watermelon Martinis pop up from girl’s night out at Granite City. This is not an exact copycat, because I have already forgotten what the last one tasted like, but they’re incredibly delicious none the less!!

🍉 How to make Watermelon Martinis

First we need to make some watermelon juice….it’s really simple, trust me. Cut up some watermelon into chunks and place them in a blender. You need about 2.5 cups of chunks.

now Puree/Liquefy the watermelon until smooth.

I used a seedless watermelon, but there were still seeds. So I poured my “juice” through a strainer to remove them.

This also removed all of the pulp, so it’s up to you to strain or not to strain….that is the question.

Pour the watermelon juice into a cocktail shaker along with the vodka and orange liqueur.

Garnish with watermelon balls on toothpicks or watermelon wedges if desired.

Now kick back and watch the fireflies. Do you have fireflies where you live? We didn’t have them in California, at least I never saw any. Maybe they don’t like smog?
