Step-by-step Preparation of Watermelon Mochi
Making watermelon mochi is a delightful process that not only fills your home with a sweet, fruity aroma but also results in a delectable treat that's perfect for any occasion. Here’s how to prepare this refreshing dessert step-by-step.
Make the Watermelon Juice
To kick off your watermelon mochi, you’ll need fresh watermelon juice. Simply take some ripe watermelon and chop it into chunks. Place the chunks into a blender, and blend until smooth. After blending, strain the mixture through a fine mesh sieve to eliminate any pulp—this ensures a smooth consistency in your mochi. You’ll want about 240ml (1 cup) of this vibrant juice.

Combine Dry Ingredients
In a mixing bowl, combine the glutinous rice flour, granulated sugar, and cornstarch. These dry ingredients are the foundation of your mochi, giving it that signature chewy texture. Stir them together thoroughly, ensuring they’re evenly blended. A consistent mix here will help with even cooking later.
Mix in Wet Ingredients
After combining the dry ingredients, it’s time to add the star of our dish! Pour in the strained watermelon juice, along with 1 ½ tablespoons of vegetable oil to enhance the smooth texture. Whisk everything together until the mixture is well combined and resembles a smooth batter. Little lumps can lead to uneven cooking, so do take this step seriously!
Cook the Mochi Mixture
Now, it’s time to bring heat into the equation. Heat a deep frypan or saucepan over medium heat and pour in your mochi mixture. Stir it consistently for about 5-8 minutes. As you stir, you’ll notice the mixture thickening and changing into a gorgeous dark pink, translucent color. This means you're on the right track, and it should feel quite sticky to the touch.
Mold and Chill the Mochi
When your mochi mixture is ready, remove it from heat. Prepare a 12cm x 12cm (or any small rectangular) mold by lining it with parchment paper. This step prevents sticking and ensures easy removal later. Pour the warm mochi into the lined mold, flatten it out with a spatula, and place it in the fridge to cool for 1-2 hours until it's slightly firm.
Cut and Dust the Mochi
After chilling, dust your work surface with cornstarch to prevent sticking. Carefully remove the mochi from the mold and place it on the dusted surface. Take a sharp, oiled knife to cut it into 12 squares. As you separate the pieces, dust each one with additional cornstarch to keep them from sticking together. Your beautiful watermelon mochi is now ready to be enjoyed!
This simple and rewarding process is sure to impress at your next gathering or serve as a delightful treat for yourself. Happy cooking!
