Prepare your glass: If you desire a sugar rim, run a lemon wedge around the rim of your chilled coupe or martini glass. Dip the rim into a shallow plate of granulated sugar. Set aside.

Combine ingredients: In a cocktail shaker, add the vodka, fresh lemon juice, and simple syrup.

Add ice: Fill the shaker with ice cubes. This is crucial for proper chilling and dilution.

Shake well: Secure the lid tightly and shake vigorously for about 15-20 seconds, or until the shaker is well-chilled on the outside.

Strain and serve: Double strain the mixture into your prepared glass. This ensures no ice shards or pulp make it into the final drink.

Garnish: Garnish with a fresh lemon twist.
