Remove containers from freezer and scrape ice with fork, mixing it from edge into center. Repeat the scraping and mixing process for another hour or so until mixtures have a nice slushy consistency.
When you're ready to serve the drinks, combine half the frozen vodka mixture, half the frozen lychee mixture, and 4 ice cubes in a blender. Puree until smooth and thick. Pour into four martini glasses garnished with mango and lychees on skewers. Repeat.
Recommended ingredient: Lychees (also known as litchis) are a fruit cultivated in subtropical regions, known for its creamy white flesh that's juicy, smooth and delicately sweet.
