At this moment, the sweet potatoes were also cooked. After Yu Bing crushed the sweet potatoes into paste and covered half of the scallion pancake skin with the sweet potato paste, she folded the remaining half and cut it into strips. Then, she picked it up and twisted it twice. Then, she brushed the egg yolk on it and sprinkled white sesame seeds. After she placed it in the oven made from the earthen kiln, she took it out 20 minutes later.
Then, it was time for the crispy potato pancakes. Yu Bing cut the potatoes into pieces first, then placed them in water to wash away the starch in the potatoes. After she added some salt, she stir-fried them until they were transparent.
The small earthen bean was taken out of the pot and poured into the bowl. Then, starch was added and laid flat in a rectangular mold. After it was cooled, it was cut into small pieces and placed in the oil pot to be fried until it was a golden crisp.
