He took a stick and stirred hard in a jar, then handed it to 'Melon Face,' instructing the young boy to continue stirring.
"You know that edible salt can dissolve in water, right?"
'Melon Face' said, "Yes."
"There's something similar in plant ash that can dissolve in water. But you have to stir it hard, or it might not dissolve completely."
"It's like putting salt into water, stirring hard, and only then will the salt granules dissolve."
Ma Lin praised him for his smartness repeatedly, then asked, "So, if you keep boiling saltwater until it evaporates, what's left at the end?"
"I've tried it; there will be salt left in the bowl at the end."
"Is it as much as the salt you put in?"
"It is."
Red Stone Village started eating salt half a year ago.
The salt was cooked out of brine.
The brine was taken from a lowland area to the south of the Red Stone Plain.
The salt production there is quite limited, but it's enough to supply a few hundred people with food.
