- Granulated sugar

- Food coloring (for a brighter pink)
See recipe card for quantities.
Instructions
Make Watermelon Juice
- Cut fresh watermelon into chunks and remove all seeds.
- Blend until completely smooth, then strain through a fine-mesh sieve to remove any pulp. You need exactly ¾ cup of smooth juice for the best texture.
Mix Ingredients
- In a microwave-safe bowl, whisk together glutinous rice flour and sugar.
- Gradually add the watermelon juice while whisking constantly to prevent lumps. The mixture should look like smooth, slightly thick pancake batter.
Cook in Microwave
- Cover the bowl with plastic wrap, leaving one corner open for steam.
- Microwave on high for 2 minutes, then stir vigorously.
- Return to microwave for 1-2 more minutes until the dough becomes translucent and pulls away from the bowl sides.
Expert Tip: The mochi is ready when it's glossy and translucent, not white. Undercooked mochi will taste gritty.
Shape the Mochi
- Let cool for 5 minutes, then dust your hands and work surface with cornstarch.
- Divide the sticky dough into 8-10 portions and roll each into smooth balls.
- Place on a cornstarch-dusted plate and enjoy!
- Step 1: Make Watermelon Juice
Blend watermelon chunks and strain to get smooth juice.
- Step 2: Mix Ingredients
Whisk flour, sugar, and watermelon juice until smooth.
- Step 3: Microwave
Microwave until the dough is glossy and pulls from the sides.
- Step 4: Shape Mochi
Dust hands with cornstarch and roll mochi into balls.
Hints & Expert Cooking Tips
- Texture troubleshooting: Too sticky? Dust in more cornstarch. Too dry or cracking? Add 1 tablespoon of watermelon juice at a time until your Watermelon Mochi is just right.
- Temperature control: Always let your Watermelon Mochi cool to room temperature before shaping; hot mochi sticks to everything and is tricky to handle.
- Juice quality matters: Pick the ripest, sweetest watermelon; the better the juice, the more flavorful your Watermelon Mochi will be without needing extra sugar.
- Microwave alternative: No microwave? Steam your Watermelon Mochi mixture for 15–20 minutes, stirring every 5 minutes for even texture.
Substitutions for Dietary Needs
- For lower sugar: Swap sugar with stevia or monk fruit sweetener; start with 1 tablespoon and adjust as needed to keep your Watermelon Mochi sweet but lighter.
- For different flavors: Replace watermelon juice with strawberry, peach, or mango juice; a fun way to give your Watermelon Mochi a fruity twist.
- For firmer texture: Add 1 tablespoon cornstarch to the mix; it gives your Watermelon Mochi a chewier bite that holds its shape beautifully.
With these tweaks, your Watermelon Mochi stays just as delicious while fitting your preferences!
Recipe Variations & Dietary Modifications
- Keto-Friendly Version: Traditional Watermelon Mochi isn’t keto, but you can try almond flour mixed with xanthan gum; the texture won’t match classic mochi, but it’s a fun alternative.
- Vegan Watermelon Mochi: Good news; Watermelon Mochi is naturally vegan; the glutinous rice flour and fruit juice contain no animal products, making it ideal for plant-based diets.
- Watermelon Mochi Ice Cream: Wrap small scoops of vanilla ice cream with mochi dough for a fusion dessert; keep the ice cream very cold and work fast to shape your Watermelon Mochi.
- Watermelon Daifuku Style: Add a sweet surprise by placing a small spoonful of red bean paste (anko) in the center before wrapping your Watermelon Mochi.
- Tropical Fruit Mochi: Swap watermelon juice for mango, pineapple, or passion fruit juice; adjust the sugar to suit your fruit’s natural sweetness.
Equipment
Essential Tools:
- Microwave-safe mixing bowl - Glass or ceramic works best for even heating
- Fine-mesh strainer - Critical for smooth watermelon juice
- Wooden spoon - Won't scratch your bowl and handles the sticky dough well
- Kitchen scale - For precise measurements that ensure consistent results
Budget-Friendly Alternatives:
- A sharp knife works instead of kitchen shears for cutting portions
- Use a regular bowl and steam on the stovetop if no microwave is available
- A clean kitchen towel can substitute for plastic wrap
Storage & Meal Prep Tips
- Meal prep strategy: Make a double batch of Watermelon Mochi on Sunday and portion into daily servings; they’re perfect for lunchboxes or afternoon snacks all week long.
- Fridge storage: Keep your Watermelon Mochi in an airtight container in the fridge for up to 3 days; use parchment between layers to prevent sticking and dust with cornstarch before serving if needed.
- Freezing instructions: Freeze individual Watermelon Mochi on a parchment-lined tray for 2 hours, then transfer to freezer bags; they’ll stay good for up to 2 months. Thaw at room temp for 30 minutes; frozen mochi gets very hard.
The Secret That Transforms Your Watermelon Mochi
I’ll let you in on a little secret I learned after a few sticky kitchen experiments: the magic of room temperature watermelon juice. The first time I made Watermelon Mochi, I rushed to use cold juice straight from the fridge; the result? Lumpy dough that was impossible to shape and lacked that dreamy, smooth texture mochi is known for.
Here’s the trick that changed everything: let your watermelon juice rest at room temperature for about 30 minutes before mixing. This simple step helps the glutinous rice flour blend like a dream, giving your Watermelon Mochi that silky, bouncy finish you’d expect from a top dessert shop. Try it once, and you’ll never skip this small but powerful secret again.
