The smell of oil refining had long woken Dong Yao up. Watching Jiang Xue's series of operations, she was utterly shocked, but she kept silent until Jiang Xue finished, then asked about it. Jiang Xue explained the principle of starting a pot to her again.
"If you don't maintain an iron pot, it will rust."
After refining the pig lard into oil, there were some oil residues left, along with a small piece of pork belly. Looking at the ingredients on hand, she wanted to make dumplings with oil residue filling, but the chopping board wasn't made yet, there wasn't even a rolling pin, and there was no suitable smooth mixing bowl either. So she simply placed a tile jar over the fire, filled it with water, added oil, and started to boil.
