Jin deui, also known as sesame balls, are a staple of dim sum culture. The hollow balls are made with a sticky rice flour dough, filled with a sweet paste, rolled in sesame seeds and fried until crispy on the outside, but soft and chewy, like mochi, on the inside. When served at dim sum, the dish is typically filled with lotus paste, lava salted egg yolk, red bean or a savory meat filling. They can also be found plain. The origins of the jin deui can be traced back to the Tang Dynasty. Depending on the region in China, jian deui comes in several variations and can go by different names.
