The Longtang Sesame Candy–making technique is a traditional handicraft of Pengshui County in Chongqing. In 2019, it was included in the sixth batch of Chongqing's municipal intangible cultural heritage representative items.

Pengshui Sesame Candy is made by simmering malt, glutinous rice, corn, and other grains in an iron pot. It does not look particularly refined: the candy is usually spread into a millstone-sized slab, wrapped in coarse cloth, its color a mix of off-white and golden brown. It is hard in texture, yet riddled with honeycomb-like pores.

When you buy it, the vendor presses a piece of iron against the edge of the candy, lifts a hammer, lets the wrist sink slightly, and with a sharp "dang," cracks the slab into irregular chunks. These pieces are then weighed on a small scale and bagged for the customer.

Though plain in appearance, the candy is very sweet. Its sweetness is unlike that of fruit sugar, and certainly not like honey, but thicker and more rustic. If you taste it carefully, you can even catch a faint hint of bitterness at the very end of that sweetness.
