Why is Chongqing's local flavor triangle bus a representative of childhood food memories?

Sanjiaoba is a classic traditional snack with Han characteristics, which is popular in Sichuan and Chongqing. It tastes crisp and refreshing, not only with the smell of rice, but also with the smell of cooking. Eating in the mouth is fragrant, crisp and sweet, so it is all the rage.

This snack is actually an improvement on the practice of white cakes. It began to rise in the late 1970s and once sold well in Sichuan and Chongqing. By the end of 1990s, it began to decline. So far, only a few booths are open.

Why triangle cake is an improvement of white cake? Because it is based on rice, just like rice cakes, it is also soaked in rice, mashed into mud and put into water. The rice cake is steamed in a steamer, which is round like a flying saucer, while the triangle cake is made by repeatedly frying rice noodles in a special pot, which is shaped like a right triangle, hence the name triangle cake.
