"Rice oil?" The curly-haired auntie spaced out for a moment.
Du Heng nodded. "Yes, it's the slightly viscous layer that floats on top when we're cooking millet porridge. Cook some thin porridge every day until it becomes very sticky, then ladle out the floating top layer and let your child drink it, twice a day. It should take about three or four days for the child's gastrointestinal function to adjust itself. By then, it's necessary to add a bit of supplementary food for the child. Whatever the adults eat, the child can eat too. Just make sure it's cooked softer, mashed up a bit, and contains less salt and oil."
The curly-haired auntie's eyes were filled with confusion and bewilderment as she asked blankly, "Can we drink that stuff? Whenever we cook porridge, we always throw away that layer. It's sticky and a bit gross to look at."
Du Heng pursed his lips tightly. "That layer is called rice oil, which is actually the most nutritious part when we cook the porridge."
