Step-by-Step Preparation for Watermelon Mochi
Creating delicious watermelon mochi is an exciting journey that begins with fresh ingredients and ends with delightful, chewy treats. Let’s navigate through the preparation of this uniquely flavored mochi together!
Making Fresh Watermelon Juice
To kick off, you’ll need about 240ml (1 cup) of fresh watermelon juice. Grab a ripe watermelon, slice it open, and cut out a few generous chunks of the flesh. Place the chunks in a blender and blend until smooth. To ensure a silky texture for your mochi, pass the mixture through a fine mesh sieve to eliminate any pulp. This step is essential because it gives your watermelon mochi that smooth, luscious flavor that bursts in every bite.
Combining Dry Ingredients
Once your juice is ready, it’s time to mix the dry ingredients. In a mixing bowl, combine 200g of glutinous rice flour (about 1 ½ cups), 65g of granulated sugar (roughly ⅓ cup), and 40g of corn starch (also about ⅓ cup). This trio forms the backbone of your mochi, giving it that characteristic chewy texture. Make sure to mix these ingredients well to create a uniform blend that sets the stage for your batter.
Mixing the Mochi Batter
Next, pour in your freshly made watermelon juice and 1 ½ tablespoons of vegetable oil into the dry mix. With a whisk, combine everything until it reaches a smooth, lump-free consistency. The vibrant pink color of your batter will make the anticipation for your watermelon mochi even more exciting!
Cooking the Mochi Mixture
Now, it’s time to transfer your batter into a medium heat pan. Use a deep frypan or a saucepan set to medium heat. Make sure to stir continuously — this helps prevent the mixture from sticking and ensures even cooking. You’ll want to keep stirring for about 5-8 minutes. When the mixture thickens and turns a delightful dark pink, almost translucent color, you’ll know it's done and ready to be removed from the heat.
Setting the Mochi in the Mold
Prepare your mold (a square mold, around 12cm x 12cm, lined with parchment paper works best). If you don’t have that exact size, any small rectangular container will suffice. Carefully pour your warm mochi mixture into the lined mold and use a spatula to flatten it evenly. This step is key for achieving beautifully shaped pieces!
Dusting and Cutting the Mochi
Once your watermelon mochi has cooled sufficiently in the refrigerator for 1-2 hours, remove it from the mold and place it on a cornstarch-dusted surface. Dust the top with a little more cornstarch to prevent sticking. Using an oiled knife, cut your mochi into 12 squares, dusting all sides with cornstarch as you go. This not only enhances the texture but also keeps them from sticking together.
And there you have it — a step-by-step guide to making scrumptious watermelon mochi! Ideal for sharing (if you can resist!), this treat offers a refreshing twist on a classic dessert. Ready to taste your creation? Enjoy!

Variations of Watermelon Mochi
Watermelon and Coconut Mochi
If you’re a fan of tropical flavors, try adding shredded coconut to your watermelon mochi. Simply mix about ½ cup of unsweetened shredded coconut into the mochi batter before cooking. The combination of juicy watermelon and chewy coconut creates a delightful texture and flavor that transports you straight to a summer beach party. It’s a refreshing twist that pairs perfectly with any gathering. For an extra hint of tropical goodness, you can even roll the finished mochi pieces in coconut flakes after cutting!
Chocolate-Dipped Watermelon Mochi
For those with a sweet tooth, chocolate-dipped watermelon mochi is a must-try! After cutting the mochi into squares, dip each piece in melted dark chocolate and let them cool on parchment paper. The rich chocolate contrasts beautifully with the sweetness of the watermelon, making it a crowd-pleaser for parties or special occasions. You can even sprinkle some sea salt on top of the chocolate before it sets to add a sophisticated touch. A bite-sized treat that will impress anyone!
Cooking Tips and Notes for Watermelon Mochi
When making watermelon mochi, it’s crucial to use fresh watermelon juice for the best flavor. Straining the juice not only removes pulp but also enhances the texture. Don’t rush the cooking process; slow and steady heating allows the mochi to develop that signature chewy quality.
Feel free to experiment with the ratio of watermelon juice to sugar based on your preferred sweetness. While it’s tempting to skip dusting with cornstarch, this step helps prevent sticking and gives your mochi a lovely finish. Finally, be sure to let your mochi cool in the fridge long enough for it to set properly. Happy cooking!
