Black sesame soup is a popular east-Asian and Chinese dessert widely available throughout China, Vietnam, Taiwan and Singapore.

It is typically served hot. In Cantonese cuisine it takes the form of tong sui, or sweet soup (similar to Western pudding), with greater viscosity. The main ingredients are black sesame seeds, rice and water. Sugar is added for sweetness. Tangyuan is sometimes added into black sesame soup. Black sesame soup can be purchased in powder form.
