Pouring sparkling water into a glass cup with green melon syrup and ice cubes for Japanese melon soda — Creating the beautiful emerald green base using pure carbonated water and melon syrup.

Step-by-Step Instructions

Create the Vibrant Emerald Base
In a tall parfaits or retro-style glass, pour 2 to 3 tablespoons of the bright green melon syrup.
Stack the Ice Cube Platform (★Crucial Kitchen Hack!)
Fill the glass all the way to the brim with ice cubes. Make sure to stack them tightly all the way to the top. This creates a solid, icy platform that prevents your scoop of vanilla ice cream from instantly sinking into the soda!
Pour the Fizzy Soda
Slowly pour 150ml of chilled sparkling water over the ice cubes. Pour gently along the inner side of the glass so the green syrup mixes beautifully and creates a gorgeous, effervescent emerald green gradient with dancing bubbles.
Crown with Creamy Vanilla
Using an ice cream scooper, place a firm, perfectly round scoop of vanilla ice cream right on top of the ice cube platform.
The Perfect Red Finish
Gently place a bright red maraschino cherry with its stem right next to or on top of the vanilla ice cream. Insert a long spoon and a straw, and serve immediately. Watch the creamy vanilla ice cream slowly melt into the sparkling green bliss!
