Step-by-step Preparation for Watermelon Mochi
Making watermelon mochi at home is a delightful experience that combines simplicity with delicious flavors. Follow this step-by-step guide to bring this soft and chewy treat to life!
Prepare the Watermelon Juice
To kickstart your watermelon mochi adventure, the first step involves extracting fresh watermelon juice. Simply chop up a ripe watermelon into smaller pieces and toss it into a blender. Blend until smooth, then strain the mixture through a fine mesh sieve into a bowl to separate the juice from the pulp. You'll want approximately 240ml (or 1 cup) of this refreshing liquid to infuse your mochi with that irresistible sweetness. For this part, you can use the juicing method outlined on Martha Stewart's website if you need some extra tips!
Combine the Dry Ingredients
In a separate bowl, combine 200g of glutinous rice flour, 65g of granulated sugar, and 40g of cornstarch. This dry mixture forms the base of your mochi, resulting in that classic chewy texture we all love. Make sure to mix them well to ensure an even distribution of ingredients—no one likes a clump of sugar in their mochi!
Mix and Heat Your Mochi Batter
Now it’s time to marry the dry quantities with your fresh watermelon juice. Add your watermelon juice and 1 ½ tablespoons of vegetable oil to the dry mixture. Using a whisk, combine until you achieve a smooth batter. Transfer the mixture to a deep frypan or saucepan, heating it over medium heat. Stir consistently for about 5-8 minutes. You’ll notice the batter thickening and shifting to a lovely, dark pink translucent color. Keep stirring; this part is crucial for achieving that sticky mochi consistency.
Pour into Molds and Cool
Get your molds ready! Line a 12cm x 12cm square container (or any small rectangular container) with parchment paper. Carefully pour the hot, sticky mochi dough into the lined mold, using a spatula to press it down evenly. This ensures your mochi maintains its shape. Once done, place the container in the refrigerator for about 1-2 hours to cool and firm up.
Cut and Dust Your Mochi
When your mochi has set, it’s time to transform it into those adorable squares. Dust your work surface generously with cornstarch to prevent sticking. Gently remove the mochi from the mold and place it on the dusted surface. Dust the top with additional cornstarch and grab an oiled knife to cut it into 12 equal pieces. Make sure to coat all sides of the mochi squares with cornstarch to keep them from sticking together. And there you have it—your delicious watermelon mochi is ready to enjoy!
This delightful treat is perfect for sharing or savoring as a unique dessert addition to any meal. Enjoy this refreshing twist on a classic!

Variations on Watermelon Mochi
Watermelon Chocolate Mochi
For a delightful twist, try adding a chocolate element to your watermelon mochi. Simply melt some dark chocolate and drizzle it over the mochi pieces just before serving. Not only does the rich chocolate enhance the sweetness of the watermelon, but it also adds a touch of decadence. If you want to elevate it further, consider rolling the mochi in cocoa powder for a dusted effect!
Matcha Watermelon Mochi
Consider blending matcha into your watermelon mochi for a vibrant flavor fusion. Mix in 1-2 teaspoons of high-quality matcha powder into the mochi batter before cooking. The earthy notes of matcha complement the sweetness of watermelon perfectly, creating a beautifully balanced treat. This variation is not only pleasing to the palate but also adds a stunning green hue, perfect for impressing friends at your next gathering.
