Prepare the Fruits: Start by cutting the watermelon and strawberries into bite-sized pieces. You can use a melon baller to create round watermelon chunks for a decorative touch. Chop peaches, and if using other fruits like mangoes or kiwis, slice them as well.
Chill the Ingredients: Refrigerate the fruits, soda, and strawberry milk before combining. This keeps the drink fresh and prevents it from becoming soggy.
Mix the Ingredients: In a large punch bowl, combine the watermelon, strawberries, peaches, and any additional fruits like berries or mangoes. Add the soda and strawberry milk to the fruit mixture.
Add Ice and Garnish: Toss in large ice cubes to keep the drink cool. Garnish with mint sprigs or edible flowers for an extra pop of color.
Serve in Clear Glassware: For the best presentation, serve the hwachae in clear glassware to showcase the vibrant fruits. Serve immediately for the freshest taste and maximum carbonation.
