This video carefully demonstrates how to make warabi mochi, a refreshing summer treat, and the homemade brown sugar syrup to accompany it. Warabi mochi is made by mixing warabi starch, brown sugar, granulated sugar, and water, then heating and patiently kneading the mixture until it has a translucent, chewy texture. The brown sugar syrup is made by simmering starch syrup, water, and brown sugar. Once chilled, topped with kinako (roasted soybean flour) and brown sugar syrup, you'll have exquisite warabi mochi that melts in your mouth.
