Step‑by‑Step Instructions for Watermelon Mochi
Step 1: Prepare Watermelon Juice
Begin by cutting fresh watermelon into chunks and blending until smooth in a blender. Strain the mixture through a fine-mesh sieve into a bowl, discarding any pulp. Allow the watermelon juice to sit at room temperature for about 10 minutes to enhance its consistency, ensuring it’s smooth and ready to incorporate into your Watermelon Mochi.
Step 2: Mix Ingredients
In a medium mixing bowl, whisk together the glutinous rice flour and sugar until combined. Gradually pour in the room-temperature watermelon juice, stirring continuously to eliminate lumps. You’ll know your mixture is ready when it forms a smooth batter that is consistent in texture. This blend will create the deliciously chewy base of your Watermelon Mochi.
Step 3: Cook Mixture
Transfer the mochi batter into a microwave-safe bowl. Cover it loosely with plastic wrap, then microwave on high for about 4 minutes. Keep a close eye on it; the mixture should become glossy and translucent. If necessary, stir halfway through cooking to ensure even heating. This step is crucial for achieving the signature texture of Watermelon Mochi.
Step 4: Shape Mochi
Once cooked, carefully remove the bowl from the microwave (it will be hot). Dust your work surface generously with cornstarch to prevent sticking. Pour the cooked mochi onto the dusted surface, allowing it to cool slightly for about 5 minutes. With cornstarch-dusted hands, shape the mochi into small balls, using about a tablespoon of mixture for each. Ensure you coat them well in cornstarch to keep them from sticking together.
Step 5: Let Mochi Cool
After shaping, place the mochi balls on a plate, ensuring they are spread apart. Allow them to cool completely for an additional 15 minutes at room temperature; this helps them firm up and enhances the chewy texture. You’ll know they are ready when they have a soft and slightly elastic feel, characteristic of a perfect Watermelon Mochi.
Step 6: Serve and Enjoy
Your Watermelon Mochi is now ready to be enjoyed! Serve chilled or at room temperature for a refreshing treat. Consider pairing them with green tea or as a delightful summer dessert at your next gathering. Be prepared for everyone to ask for more of these delightful, chewy delights!

Expert Tips for Watermelon Mochi
- Room Temperature Juice: Ensure your watermelon juice is at room temperature before mixing; cold juice leads to lumpy texture in the Watermelon Mochi.
- Check Consistency: Aim for a smooth batter without lumps; overmixing can create air bubbles, affecting the mochi’s texture.
- Watch the Cooking Time: Keep an eye on the microwave; undercooked mochi will be gritty and too chewy, while overcooked can become tough.
- Dust Generously: Don’t skimp on cornstarch during shaping; this prevents sticking and helps you achieve the perfect, bite-sized balls of Watermelon Mochi.
- Storage Tips: For best taste, enjoy your mochi fresh; however, if storing, keep them in an airtight container at room temperature to maintain texture.

Watermelon Mochi Recipe FAQs
How do I choose the best watermelon for juice?
Absolutely! When selecting a watermelon, look for one that feels heavy for its size and has a uniform shape. The skin should be a dull matte finish rather than shiny, and check for a yellow spot on the bottom—the sweeter it is, the better the flavor for your Watermelon Mochi!
How should I store leftover Watermelon Mochi?
For optimal taste, enjoy your Watermelon Mochi fresh. If you have leftovers, place them in an airtight container at room temperature for up to 2 days. For extended storage, refrigerate them for up to 3 days, making sure they’re covered to prevent drying out.
Can I freeze Watermelon Mochi? How?
Yes, you can freeze Watermelon Mochi! Start by laying them in a single layer on a baking sheet and freeze until solid, about 1-2 hours. Once frozen, transfer them to an airtight container or freezer bag, separating layers with parchment paper to prevent sticking. They can be stored for up to 1 month—simply thaw in the fridge before enjoying.
What can I do if my Watermelon Mochi turns out lumpy?
Very! If your Watermelon Mochi has lumps, it’s likely due to not mixing the ingredients thoroughly or using cold watermelon juice. To salvage it, you can strain the mixture after mixing to remove lumps before cooking. If it’s already cooked, you might need to adjust the cooking time and blend it again to create a smoother consistency next time.
Are there any dietary considerations for pets or allergies?
While Watermelon Mochi is vegan and gluten-free, it is important to note that mochi is sticky and can pose a choking hazard for pets. Additionally, anyone with rice flour allergies should avoid this recipe. Always be cautious and check with your guests if anyone has specific dietary concerns before serving.
What should I do if my mochi is too tough or gritty?
Oh no! If your mochi comes out tough or gritty, it might be undercooked or overcooked. Aim for a glossy, translucent finish when microwaving—if it appears too tough, lower the cooking time in future batches. An undercooked version can often be salvaged by mixing it again with a splash of hot water to soften before re-cooking for a few seconds.
