Watermelon Mochi Recipe
Introduction
Watermelon mochi is a delightful and refreshing twist on the traditional Japanese treat. Combining the sweet, juicy flavor of watermelon with the chewy texture of mochi, this recipe is perfect for warm days or anytime you want a light, fruity dessert.

Ingredients
- 1 cup Glutinous rice flour (also called mochiko)
- 3/4 cup Fresh watermelon juice (blended and strained)
- 1/4 cup Granulated sugar (adjust based on the sweetness of the watermelon)
- As needed Cornstarch or potato starch (for dusting)
Instructions
- Step 1: Blend fresh watermelon and strain the juice to remove any pulp or seeds.
- Step 2: In a bowl, whisk together the glutinous rice flour, granulated sugar, and the fresh watermelon juice until smooth.
- Step 3: Microwave the mixture in a microwave-safe bowl for about 1 minute, then stir. Repeat microwaving in 30-second intervals, stirring between each, until the dough becomes glossy and slightly translucent.
- Step 4: Dust your work surface and hands with cornstarch or potato starch. Transfer the mochi dough onto the surface and shape it into small balls or desired shapes while still warm.
Tips & Variations
- If the watermelon is very sweet, reduce the sugar to avoid overly sweet mochi.
- For a fun twist, add small bits of fresh watermelon or mint into the dough before cooking.
- Use potato starch if you prefer a less powdery texture on the surface compared to cornstarch.
Storage
Store watermelon mochi in an airtight container at room temperature for up to one day. Because of the fresh fruit juice, it’s best eaten fresh. For longer storage, refrigerate and bring to room temperature before serving, though the texture may become firmer. Avoid freezing, as it can alter the mochi’s texture.

FAQs
Can I use watermelon puree instead of juice?
It’s better to use strained juice to avoid excess moisture and pulp, which can affect the texture. If using puree, make sure to strain it well or reduce the quantity slightly.
Can I substitute microwave cooking with steaming?
Yes, you can steam the mochi mixture for about 10–15 minutes until it becomes glossy and sticky. Stir midway to ensure even cooking.
