Ming Zhiyan had finished listening and had memorized everything Jian Qingqing had said, she asked, "What if we make it into flour? Do we grind it into powder like flour?"
"Yes..." Jian Qingqing pondered for a moment. She knew that corn was dried and ground into powder, and sweet potatoes seemed to be the same. When she was watching the video, she had seen people making potatoes by hand and directly crushing them into juice. Then, the powder can naturally settle down. After it was dried, it would be potato starch. She just did not know if there were any other good methods.
She told him all the methods of making the three crops. "Sweet potatoes and corn are both dried and ground into powder. For potatoes, they are ground into powder and then let it settle down. What settles down is potato starch. It should be enough to dry it under the sun."
