Essential Ingredients for Watermelon Mochi
To create your delightful watermelon mochi, you’ll need a handful of essential ingredients that come together beautifully. Here’s what you’ll need:

- Granulated sugar (65g or ⅓ cup): Sweetness is key! This adds the perfect balance to the refreshing watermelon.
- Cornstarch (40g or ⅓ cup): Used for dusting and thickening, it helps keep the mochi from sticking together.
- Watermelon juice (240ml or 1 cup): Freshly strained juice is a must for that authentic watermelon flavor.
- Vegetable oil (1 ½ tbsp): This helps achieve a smooth, pliable dough.
These simple ingredients pave the way for a mochi that’s not just tasty, but also fun to make!
Optional Add-ins for Extra Flavor

Preparing Watermelon Mochi
Making your own watermelon mochi at home is not just fun but also incredibly rewarding! Follow these steps to create a delightful treat that’s soft, chewy, and bursting with fresh watermelon flavor.
Make the Fresh Watermelon Juice
To start, you'll need to create your watermelon juice. This is the magic ingredient that gives the mochi its vibrant color and taste. Simply take some fresh watermelon, chop it into chunks, and place it in a blender. Blend until smooth, then pass the mixture through a fine mesh sieve to remove any pulp. This will give you about 240ml of pure watermelon juice—sweet, refreshing, and perfect for your mochi.
Combine the Dry Ingredients
In a mixing bowl, grab your dry ingredients: glutinous rice flour, granulated sugar, and corn starch. These components work together to create that iconic chewy texture in the watermelon mochi. Whisk them together until they are well combined. The sugar not only adds sweetness but also helps the mochi rise as it cooks.
Mix and Whisk Until Smooth
Next, pour in your freshly made watermelon juice along with 1 ½ tablespoons of vegetable oil. Use a whisk to mix everything together until it becomes a smooth batter. It’s important to eliminate any lumps, as they could affect the final texture. You should end up with a lovely, bright pink mixture that smells delightful.
Cook the Mochi Mixture
Now comes the fun part! Use a deep frypan or saucepan and heat it over medium heat. Pour the mochi mixture into the pan. Stir continuously for about 5-8 minutes. You’ll notice the mixture thickening and changing to a dark pink, translucent color. Be attentive during this stage; the consistency should be very sticky and stretchy.
Set the Mochi in the Mold
Once the mixture is ready, remove it from the heat and prepare a square mold (about 12cm x 12cm). Lining it with parchment paper can make it easier to remove later on. Pour your warm mochi mixture into the mold and use a spatula to flatten it out evenly.
Slice and Dust the Mochi
After letting your mochi cool in the fridge for 1-2 hours until it’s slightly firm, dust your work surface with cornstarch to prevent sticking. Carefully remove the mochi from the mold and place it on the dusted surface. Cut it into squares using an oiled knife to minimize sticking. Make sure to dust the pieces with additional cornstarch, so they don't stick together.
And voilà! You’re ready to enjoy your homemade watermelon mochi. It’s perfect as a light dessert or a refreshing snack on warm days. Share your creations with friends or keep them all to yourself—they're worth savoring! For more treats, check out some fantastic options on Serious Eats for ideas.

Cooking Notes for Watermelon Mochi
Tips for Achieving the Right Texture
To ensure your watermelon mochi comes out perfectly soft and chewy, make sure to stir the mixture continuously while cooking. This helps in achieving that elusive stretchy texture. If it's too thick, you can add a splash more of watermelon juice. For easy handling, dust your surface with cornstarch—this will assist in cutting the mochi without sticking.
Common Mistakes to Avoid
A common pitfall is undercooking the mochi mixture; make sure it becomes a sticky, dark pink consistency. If possible, measure your ingredients accurately—too much flour can lead to a dry texture. Lastly, be patient during the cooling time; rushing this step can affect the mochi's final softness. For more tips on mochi-making, check out Serious Eats.
