Mochi glutinous rice balls, also known as mochi tangyuan, are a popular dessert in Japanese cuisine. These sticky rice balls are made by mixing glutinous rice flour with water to form a dough, which is then filled with various sweet fillings such as red bean paste, matcha, or fruit. The filled dough is rolled into small balls and cooked in boiling water until they become soft and chewy. The cooked rice balls are then coated in a dusting of kinako (roasted soybean flour) or served with a drizzle of sweet soy sauce. The combination of the soft and chewy mochi with the flavorful fillings creates a delightful and satisfying dessert.
