"And this." Fang Hai continued the introduction for Emperor Yongan. He took a palm-sized, lake blue bowl from the food box. The bowl contained rich soybean paste, knowing the emperor's preference for cane sugar, he proactively added some, "This is soymilk, in which dried soybeans are soaked and then ground on a stone mill into a paste, then it's boiled. This is how soymilk is made."
Emperor Yongan was somewhat surprised, "So many variations?"
"Indeed, the people in the Imperial Kitchen say that this food is no worse than cold jelly noodles." Fang Hai put the bowl in front of Emperor Yongan.
Upon hearing this, a slight smile touched the corner of the emperor's mouth. "The prime ministers are so considerate."
Creating more variations from two inexpensive ingredients like soybeans and sweet potato, which couldn't be used as staple food, was also a kind of contribution.
"Has it been popularized?" He asked.
