Cut fresh watermelon into 1/2 inch cubes and freeze.
For each martini, place the following into a shaker:
3 oz. vodka
1 oz. sweetened lime juice like Roses Lime
1 oz. Triple Sec
1 oz. Chambord
12 frozen watermelon cubes
Shake until cubes are dissolved, leaving small shards that float on the drink when strained. The original recipe is half the amount above, but my martini glasses are large and I had to double the ingredients!
This was a nice starter for our grilled Filet Mignon Father's Day dinner!
