C491: Saltpeter to make Ice

Tang Mingrui knew very well that the corn seeds from the Mo Family were meant to be sold to the government, and he only had one year to make high profits from it.

Although corn cakes were delicious, it was obvious that dishes made from fresh corn would be much more profitable.

He looked at He Zhiran: "Sister-in-law, do you have any ideas on how to preserve the freshness of corn?"

In Tang Mingrui's impression, not only was his sister-in-law very smart, she was also very knowledgeable, so perhaps she could come up with a good way to preserve corn.

When asked by Tang Mingrui, the first thing He Zhiran thought of was that fresh corn could be frozen for preservation.

The only way to freeze food during this season was to make ice.

It was no secret that people in the previous era used nitrates to make ice, something many children did in science experiments.

"Fresh corn can be preserved by freezing," she said.

Tang Mingrui: ...

"Sister-in-law, what you said is the same as not saying anything. Even though the weather now is not as hot as summer, where can I get ice?

If I had known earlier, I would have gotten someone to store some ice cubes last winter. It's probably too late now," Tang Mingrui said, clearly somewhat discouraged.

In his knowledge, the ice cubes people used in summer were all preserved from winter.

Many mountain caves had extremely low temperatures. The ice cubes people stored in winter were kept in this kind of cave.

Not to mention these cold, gloomy caves were not easy to find, transporting the ice cubes was also a huge project, and many wealthy families hired a large number of workers to do it.

Even so, although the caves were cold, they were still not as cold as the winter air temperature, so the ice cubes stored inside could only slow down the melting.

By the time the ice cubes were used in summer, even the best ones would have lost half their volume to natural melting.

As a result, ice cubes were extremely precious in Da Shun in summer, and very few could afford them.

He Zhiran took in Tang Mingrui's disappointed expression.

She laughed and said, "Brother Tang doesn't need to worry about ice cubes. You just need to find a bigger place, the bigger the room the better, large enough to store the fresh corn you want to eat."

Tang Mingrui was puzzled by her words, but found a bigger place was no problem. The courtyard he had bought for his family was very spacious, with many extra rooms.

He just could not understand what his sister-in-law was going to do. If he took her words literally, it meant his sister-in-law could get ice cubes.

"Sister-in-law, what do you mean?"

"It's just as you thought, I can get ice cubes." He Zhiran was not too serious, but her tone inexplicably gave people an indisputable feeling.

Tang Mingrui was even more willing to believe her unconditionally. He stood up,

"Okay, I'll go back and arrange a bigger room now."

He was about to leave when He Zhiran called him back.

"Brother Tang, don't rush. It will take three days for my ice cubes to be ready. For the empty room you prepare, seal all four sides with mud, completely airtight except for the door. Only this way will the ice cubes not melt easily when stored inside."
