Classic Lemon Drop Vodka Cocktail

0 If rimming your glass with sugar, first cut a lemon in half and run one half along the outside edge of your glass. Next, roll that outer edge in a shallow dish of sugar. Turn the glass upside down to shake out any excess sugar that may have fallen in the glass.
1 Next, combine the vodka, lemon juice, triple sec, and simple syrup in a cocktail shaker. Fill it three quarters with ice and shake until chilled.
2 Strain into your sugar-rimmed glass and garnish with a lemon twist, if desired.
