Chill your glass: Place a martini or coupe glass in the freezer for at least 10 minutes. A cold glass keeps the drink crisp longer.
Prep your garnish: Thread a lychee or two onto a cocktail pick. If using fresh lychee, peel and pit gently.
Measure the base: Add 2 ounces vodka to your shaker.
Add lychee: Pour in 1.5 ounces lychee syrup or juice.
For a drier drink, use juice; for a sweeter profile, use the syrup.
Layer in nuance: Add 0.25–0.5 ounce dry vermouth or lychee liqueur, depending on how floral you like it.
Brighten with citrus: Squeeze in 0.25–0.5 ounce fresh lime juice. Start small; you can always add more.
Ice and shake hard: Fill the shaker with ice, seal, and shake for 12–15 seconds. You want a frosty shaker and a well-chilled drink.
Strain and serve: Double strain into your chilled glass to catch ice chips and pulp.
The result should be silky and clear.
Garnish: Add your lychee skewer and, if you like, a thin lime wheel on the rim.
Taste and tweak: If it’s too sweet, add a dash more lime and shake again. If it’s too tart, add a splash more lychee syrup.
