Step 1: Craft the Red Hot Cinnamon Liqueur (Do This Ahead of Time)
In a saucepan, combine the Red Hots candies, water, and optional sugar. Heat over medium heat, stirring frequently, until the candies are completely dissolved into a smooth syrup. Remove from heat and let the syrup cool completely to room temperature. Once cool, stir in the vodka. Transfer the mixture to a clean jar, seal it, and let it infuse for at least 24 hours (48 is better). The flavor will deepen over time. Store indefinitely in a cool, dark place.

Step 2: Prepare the “Snowy” Glass
Chill a highball or collins glass in the freezer for at least 15 minutes. Take the chilled glass and rub the rim with a lime wedge. Dip the moistened rim into a shallow plate of powdered sugar, twisting to create a beautiful, even “snowy” rim.

Step 3: Combine the Core Ingredients
Fill the prepared glass with ice. Pour the Advocaat, Red Hot Cinnamon Liqueur, and fresh lime juice over the ice.

Step 4: The Fizzy Top-Up
Top the glass with the chilled lemon-lime soda. The soda provides a necessary brightness and effervescence that lightens the rich, creamy base.

Step 5: Integrate Gently
Use a long bar spoon or a straw to give the drink one gentle stir, just to combine the layers. Over-stirring will cause it to lose its carbonation.

Step 6: The Final Garnish
For a professional touch, garnish with a cinnamon stick placed in the glass, which also doubles as a stirrer. You can also add a few whole Red Hots candies or a star anise pod for extra visual flair.

Step 7: Serve Immediately
Serve right away while the glass is frosty and the soda is still bubbly. Enjoy the captivating contrast of flavors and temperatures!
