Common Mistakes to Avoid

When making Watermelon Mochi, it’s easy to make a few common mistakes. Here are some tips to help you succeed.

  • Bold ingredient measurements: Not measuring ingredients accurately can ruin your mochi’s texture. Use a kitchen scale for precise measurements.
  • Bold neglecting the dusting: Forgetting to dust the cooked glutinous rice flour can make your mochi sticky. Always dust your hands and surfaces before handling the dough.
  • Bold overcooking the mixture: Cooking the dough too long can lead to a rubbery texture. Cook just until it’s smooth and slightly translucent.
  • Bold using unripe watermelon: Using an unripe watermelon will affect both flavor and moisture content. Choose a ripe watermelon for the best results.
  • Bold skipping the chilling step: Not allowing the mochi to chill can result in a gooey mess. Chill in the refrigerator for at least 30 minutes before serving.
