Laobeijing mati sesame seed cake

A famous snack in old Beijing, "horseshoe sesame seed cake", was first introduced to Beijing from Jinan, Shandong Province. It has a history of more than 200 years, but it has basically disappeared now, because it is baked in a hanging furnace, and molds are needed in the furnace.
