"Brown sugar manju" is a Japanese confectionary known for its gentle sweetness and fluffy texture. In this video, the dough, made by mixing boiling water in which brown sugar has been dissolved, baking soda, and cake flour, is left to rest in the refrigerator. Then, moist red bean paste (or black sesame paste) is carefully wrapped inside, and the dough is shaped. Steaming them in a bamboo steamer results in plump, visually appealing, and authentic brown sugar manju. This recipe is perfect for those who want to easily enjoy authentic Japanese sweets at home, for entertaining guests, or for creating a home café experience.
