Strawberry Martini

Chill four martini glasses by filling them with ice water and setting aside for at least 2 minutes, then empty and set aside.

Hull the fresh strawberries and slice them in half lengthwise, reserving one half per serving for garnish.

Place the remaining strawberry halves into a cocktail shaker and gently muddle to release their juices without crushing them into a pulp.

Add 2 shots of Stolichnaya vodka, ½ shot of crème de cassis, and ½ shot of fresh lime juice to the shaker.

Fill the shaker with ice and shake vigorously for 10-15 seconds until well chilled and combined.

Pour the caster sugar onto a small plate and rim each chilled martini glass by moistening the edge with a strawberry slice, then dipping into the sugar.

Strain the cocktail mixture into the prepared glasses, dividing evenly among the four servings.

Garnish each glass with a reserved fresh strawberry slice perched on the rim and serve immediately.
