Begin by selecting a tall, clear glass to showcase the beautiful layered effect of the drink.

Fill the glass with crushed ice all the way to the top; this helps maintain temperature and enhances texture.

Gently tap the glass to settle the ice, ensuring there are no large air gaps.

Slowly pour the chilled lemon-lime soda over the crushed ice, allowing it to flow evenly and preserve carbonation.

Leave a little space at the top of the glass for the remaining ingredients.

Add the raspberry syrup by pouring it directly over the ice; it will naturally sink and create a vibrant red layer.

Do not stir at this stage—this is key for achieving the signature marbled look.

In a small cup, measure the half-and-half or heavy cream.

Slowly drizzle the cream over the soda, pouring it gently to allow it to cascade through the drink.

Watch as the cream forms soft, cloud-like swirls mixing with the raspberry syrup and soda.

Let the drink sit for a few seconds so the layers can settle into a visually appealing pattern.

If you prefer a more blended flavor, give the drink a very light stir once or twice.

Taste the drink and adjust sweetness if needed by adding a little more raspberry syrup.

For a thicker, richer texture, add an extra tablespoon of cream.

Garnish with fresh raspberries on top for an elevated presentation.

Optionally add a striped straw for a fun, café-style aesthetic.

Serve immediately while the soda is still fizzy and refreshing.

Avoid over-mixing to preserve both texture and appearance.

Ensure all ingredients are chilled beforehand for the best experience.
