Preparation:

Step 1: Combine the cranberry juice, freshly squeezed lemon juice, simple syrup, and gin in a cocktail shaker.
Step 2: Add ice cubes to the shaker, filling it about halfway, and shake vigorously for 15-20 seconds until the mixture is well-chilled.
Step 3: Fill a Collins glass or tall highball glass with fresh ice cubes to keep the drink cold.
Step 4: Strain the chilled cranberry mixture into the prepared glass, leaving enough room at the top for sparkling water or club soda.
Step 5: Top off the drink with sparkling water or club soda, stirring gently to combine without losing the bubbles.
Step 6: Garnish the drink with fresh cranberries, a lemon slice, and a sugared rosemary sprig or mint for a festive presentation. Serve immediately and enjoy.

The key to making Frosty’s Cranberry Collins truly shine is in the details. Using fresh lemon juice instead of bottled ensures a vibrant, fresh flavor that elevates the entire drink. Similarly, opting for high-quality cranberry juice—preferably unsweetened—allows you to control the sweetness and maintain the cocktail’s tart character. Simple syrup can be easily adjusted based on your preference for sweetness, and making it at home ensures a fresher and cleaner taste. For the sparkling element, club soda is the classic choice, but flavored sparkling water such as cranberry or lemon-lime can add an extra layer of flavor. Garnishes are not just decorative; they also enhance the drink’s aromatic appeal. Sugared rosemary sprigs, in particular, add a wintry touch that pairs well with the cranberry and lemon.
