Feeling kind of brilliant here.
Freeze chunks (cubes) of fresh watermelon and use them as "ice" cubes to chill your drink!
Doesn't matter what you like best.... would be great in a gin and tonic or a vodka tonic.
Hmmm, I got a question for you!
Why do people say gin AND tonic and just, vodka tonic (no AND)???
No recipe here... I figure you know how to make a Vodka Tonic.
Just freeze up some watermelon and you're most the way to SUMMERTiME!
