- 1 1/2 oz gin
- juice of half lime
- 1 oz creme de cassis
- 1 oz watermelon syrup*
- Champagne
- sugar for rimming (optional)

Mix all ingredients except in a cocktail shaker with ice. Strain into a chilled martini glass rimmed with sugar (optional). Top with Champagne.

Watermelon Syrup
To make watermelon syrup, mix 4 cups pureed seedless watermelon and 1 cup granulated sugar in a saucepan over medium heat and stir while bringing to a simmer. Adjust the heat to maintain a simmer. Stirring occasionally, simmer until the mixture has reduced by one half in volume and becomes syrupy. Remove from heat to cool and then place in a glass bowl or jar, cover and refrigerate until ready to serve. Keeps 5 days in the refrigerator. Makes 2 cups.
