Fill your tall glass with ice, leaving about 2 inches at the top for mixing. Use fresh, clean ice for the best taste and presentation. Pro tip: Chill your glasses in the freezer for 10 minutes before making drinks for an extra-cold experience.

In a small bowl, gently whisk together the heavy cream and your chosen syrup until well combined. This prevents the syrup from sinking to the bottom of your drink. Pro tip: Don't over-whisk – you want it smooth, not whipped.

For coconut versions, make sure to stir the canned coconut cream first as it tends to separate naturally. Pro tip: Room temperature syrups mix more easily than cold ones.

Pour the cream mixture over the ice in your prepared glass, distributing it evenly. Pro tip: Pour slowly to create beautiful layers that will mix naturally as you drink.

Slowly pour the chilled soda down the side of the glass to preserve carbonation and create a lovely marbled effect. Pro tip: The key is pouring gently – aggressive pouring kills the fizz that makes these drinks special.

Give the drink a gentle stir with a long spoon, just enough to partially combine the ingredients while maintaining some marbling. Pro tip: Leave some cream streaks visible – they look beautiful and taste amazing as they slowly mix.

Add any desired garnishes like whipped cream, cherries, or toasted coconut flakes. Serve immediately with a straw and long spoon. Pro tip: Take a photo before the first sip – these drinks are incredibly photogenic and perfect for social media!
