Chill a martini glass in advance to ensure it's cool and ready for serving.

Prepare a garnish by skewering fresh blackberries for an elegant touch.

In a mixing glass, combine Ketel One Vodka, Hayman's London Dry Gin, crème de cassis liqueur, Strucchi Dry Vermouth, and chilled sweetened cranberry juice.

Add ice to the mixing glass and stir the mixture thoroughly until well-chilled.

Fine strain the cocktail into the pre-chilled martini glass to remove any ice shards.

Garnish the drink with the skewered blackberries for a visually appealing finish.
