This video introduces a simple recipe for warabi mochi (bracken starch jelly) with a bouncy texture, made by mixing just three ingredients—potato starch, granulated sugar, and water—heating it, and then letting it cool. The process of heating and stirring until it becomes transparent, and then shaping it with cold water, is fun and feels like an experiment. Serve it with kinako (roasted soybean flour) and kuromitsu (brown sugar syrup) to easily enjoy this refreshing Japanese sweet at home, perfect for summer.
