Prepare the Glass: If you like a sugar-rimmed glass, start by running a lemon wedge around the rim of a martini glass. Dip the rim into a plate of sugar to coat it. Set the glass aside.

Mix the Ingredients: Fill a cocktail shaker with ice. Add the vodka, limoncello, lemon juice, and cranberry simple syrup.

Shake: Shake the mixture well until it's chilled.

Strain and Serve: Strain the mixture into the prepared martini glass.

Garnish and Enjoy: Garnish with a lemon twist or fresh cranberries if desired. Enjoy your Cranberry Lemon Drop Martini.
