- As needed tbsp cornstarch or potato starch (for dusting)
Instructions
- Step 1: Prepare the watermelon juice by blending fresh watermelon and then straining it to remove any pulp.
- Step 2: In a bowl, whisk together the glutinous rice flour, granulated sugar, and fresh watermelon juice until the mixture is smooth and well combined.
- Step 3: Microwave the mixture for about 2 minutes, then stir and microwave again for another 1–2 minutes until the dough becomes glossy and sticky.
- Step 4: Dust your hands and workspace with cornstarch or potato starch to prevent sticking. Shape the mochi dough into small balls while it is still warm, then let them cool before serving.
Tips & Variations
- If fresh watermelon is not available, use good-quality watermelon juice or puree for similar flavor.
- Add a pinch of salt to balance sweetness if your watermelon juice is very sweet.
- Try filling the mochi with small pieces of fresh fruit or sweet red bean paste for extra texture and flavor.
- Use potato starch instead of cornstarch if you prefer a smoother finish on the mochi surface.
Storage
Store watermelon mochi in an airtight container at room temperature for up to one day, as mochi tends to harden over time. For longer storage, refrigerate for up to 2 days, but allow them to come to room temperature before eating. Avoid freezing as it can affect the texture.

Ingredients
Watermelon Mochi Ingredients
- 1 cup Glutinous rice flour (Also called mochiko)
- 3/4 cup Fresh watermelon juice (Blended and strained juice)
- 1/4 cup Granulated sugar (Adjust if watermelon is sweet)
- As needed tbsp Cornstarch or potato starch (For dusting)
Instructions
- Juice: Begin by blending fresh watermelon chunks to extract juice. Use a blender to create a smooth puree, then strain the juice through a fine mesh sieve to remove pulp and seeds, ensuring a smooth liquid base for the mochi.
- Mix: In a mixing bowl, whisk together the glutinous rice flour, granulated sugar, and the freshly strained watermelon juice until the batter is smooth and free of lumps. Adjust sugar quantity based on the sweetness of the watermelon to maintain balanced flavor.
- Cook: Transfer the batter to a microwave-safe bowl. Microwave the mixture on high in 30-second intervals, stirring well between each interval, until the mochi dough becomes shiny, glossy, and slightly translucent. This process usually takes about 1.5 to 2 minutes total.
- Shape: Dust a clean work surface and your hands lightly with cornstarch or potato starch to prevent sticking. Once the cooked mochi dough is cool enough to handle yet still warm, pull off small portions and shape them into smooth, round balls or discs. Dust each piece with extra starch to keep them from sticking together.
Notes
- Use ripe, sweet watermelon for the best flavor in your mochi.
- If you don’t have a microwave, you can cook the mixture on the stovetop over low heat while stirring continuously until it thickens and becomes glossy.
- Adjust sugar to taste depending on watermelon sweetness and personal preference.
- Keep your hands and surface well dusted with starch to prevent the mochi from sticking.
- Store leftovers in an airtight container at room temperature and consume within one day for the best texture.
