Ingredients

  • 100 g bracken starch (or tapioca starch)
  • 400 ml water
  • 80 g sugar
  • roasted soy flour (for dusting, to taste)

Steps

  1. In a saucepan, combine bracken starch, water, and sugar. Whisk over medium heat for about 10 minutes until the mixture thickens and becomes clear.

  2. Once the mixture is clear and elastic, pour it into a mold or a shallow dish. Allow it to cool at room temperature for at least 15 minutes.

  3. Once cooled, refrigerate for 1-2 hours until firm. Cut the jelly into bite-sized pieces.

  4. Dust the pieces generously with roasted soy flour before serving to enhance flavor and texture.

Why this works

The beauty of Warabimochi lies in its unique texture, achieved through careful heating of the bracken starch mixture. As the starch is whisked with water and sugar, the heat causes the starch granules to swell and release amylose, transforming the cloudy mixture into a clear, elastic jelly. This reaction is crucial for achieving the desired springy consistency. If your mixture seems too thick before reaching clarity, simply add a splash of water and continue heating while whisking vigorously. On the other hand, if the mixture breaks and separates instead of becoming smooth, it may have been overheated; reduce the heat and whisk gently until combined again. The final dusting of roasted soy flour not only adds a nutty flavor but also prevents the pieces from sticking together, making it easier to enjoy this refreshing treat.
