Instructions for Making Watermelon Soju Punch
Let’s dive into the fun part — pulling it all together into one icy, fruity masterpiece.
1. Preheat Your Equipment:
There’s no heat involved here, but make sure your bowl and all ingredients are thoroughly chilled.
2. Combine Ingredients:
Scoop the watermelon into balls using a melon baller. Add them to the bowl along with lemon slices and mint.
3. Prepare Your Cooking Vessel:
Place the large bowl on your table or tray, add in the soju and give it a gentle stir.
4. Assemble the Dish:
Pour in the lemon-lime soda and, if using, the sweetened condensed milk. Stir gently to combine everything evenly.
5. Cook to Perfection:
No cooking here, just let the flavors mingle. You can refrigerate for an hour if you prefer a deeper infusion.
6. Finishing Touches:
Add ice cubes just before serving to keep everything chilled without watering it down too soon.
7. Serve and Enjoy:
Use a ladle to scoop the punch and fruit into individual glasses or bowls. Garnish with extra mint or citrus if you like.
Texture & Flavor Secrets
The magic of this punch lies in its play of textures — juicy bites of watermelon, the fizz of soda, and cool mint swirling in every sip. The flavor is sweet but balanced by citrus and herbs, with a mellow kick from the soju. It’s light, refreshing, and totally addictive.
Cooking Tips & Tricks
Here are a few extra ways to make your punch pop:
- Use a chilled metal bowl to keep it cold longer.
- Add a splash of fruit juice (like pineapple or orange) for extra depth.
- Freeze some watermelon balls ahead of time to use as ice cubes.
What to Avoid
Even the simplest drinks can go sideways. Here’s what to steer clear of:
- Adding soda too early — it’ll go flat before serving.
- Overcrowding with too many mix-ins — keep it clean and focused.
- Using warm ingredients — they’ll melt the ice too fast and dull the flavors.

Make-Ahead and Storage Tips
If you want to prep ahead, scoop the watermelon and slice the lemon in advance. Store them in the fridge in airtight containers. Mix the punch just before serving to keep the soda bubbly. Leftovers can be stored in the fridge for a day, but the fizz will mellow out. Don’t freeze once mixed.
How to Serve Watermelon Soju Punch
Serve it in a clear glass bowl with a big ladle for scooping into small cups or cocktail glasses. Add colorful straws or garnish each cup with a fresh mint leaf or lemon wheel for flair. It’s perfect alongside grilled meats or spicy snacks.
Creative Leftover Transformations
Left with a bit of punch? Blend it with ice into a slushy, or freeze it in popsicle molds for refreshing boozy treats. The fruit can also be tossed into a salad with feta and arugula.
Additional Tips
Want to get a little extra with it?
- Add edible flowers for a visual wow factor.
