Pink Grapefruit and Lychee Cocktail

Pink grapefruit, a popular winter fruit, plays a major role in this beautiful drink. Look for canned lychee fruits with a delicate sweet taste in the ethnic food section of the supermarket or in Asian grocers. Use leftover lychee in a fruit salad. If you are preparing our cocktail menu for a party, you will want to repeat this recipe.
Drain the lychees in a colander over a bowl; reserve 1 cup of syrup. Drain the remaining liquid. Place 1 lychee in the bottom of each of the 5 glasses; fill each glass halfway with crushed ice. Save the remaining lychees for another use.Combine the reserved 1 cup lychee syrup, juice, and vodka in a large martini shaker half filled with ice; beat until completely cooled. Pour 1/2 cup of the syrup mixture into each prepared glass; garnish each serving with 1 grapefruit slice. Serve immediately.
