Watermelon Mochi Recipe FAQs
What is the best way to select ripe watermelon for this recipe?
Absolutely! Look for a watermelon that is vibrant in color and feels heavy for its size. When you tap it, listen for a hollow sound — that’s a great indicator of ripeness! If it has any dark spots, it’s perfect! Using a ripe watermelon makes all the difference in flavor for your watermelon mochi.
How should I store watermelon mochi?
To maintain its delightful texture, store watermelon mochi in an airtight container at room temperature if you plan to eat it within the same day. For longer storage, keep it in the refrigerator for up to 3 days. Just remember to cover it well to prevent it from drying out!

What can I do if my mochi turns out too tough?
