Sesame glutinous rice balls, also known as black sesame tangyuan, are a popular dessert in Chinese cuisine. These sticky rice balls are made by mixing glutinous rice flour with water to form a dough, which is then filled with a sweet black sesame paste. The filled dough is rolled into small balls and cooked in boiling water until they float to the surface. The cooked rice balls are then coated in a mixture of ground roasted sesame seeds and sugar, giving them a nutty and sweet flavor. Sesame glutinous rice balls are often served as a dessert during festivals and special occasions.
