Yellow beans with yu tiao = tao suan
Its mung beans, and mung beans are green beans, like in green
bean soup. But the beans in tao suan are actually deshelled green
beans, achieved by soaking green beans overnight.
If you wonder why tao suan is so hard to find, and why most
dessert stalls offer them, its because it is labour intensive to
make. Not worth the time and money.
