Lychee Martini

1. To make the lychee juice: Add 1 can of lychee (including its juices) to a blender along with the juice of 1/2 lemon, 1 teaspoon of vanilla extract (optional), and 1/2 cup of water. Blend until smooth. Strain the mixture to remove any pulp.
2. To prepare the martini: In a shaker, combine 2 parts of the strained lychee juice with 1 part vodka (you can make it equal parts if you prefer a stronger drink). Add a generous amount of ice and the juiced lemon half. Shake well until thoroughly chilled.
3. Serve immediately and garnish with additional lychee fruit from the second can, if desired.
