"Is this all in the coarse salt we usually eat? No wonder there is always sand in it."
The Six of Hearts looked at the sand and dirt stuck to the brocade cloth with great surprise.
"Yes, these are just insoluble impurities. Let's sift them out twice more."
Song Che washed the brocade cloth and filtered it three times in a row, and the brine obtained was obviously much clearer.
At this time, the Four of Diamonds and the Five of Clubs also found quicklime.
Song Che's quicklime and plant ash were each mixed into a dissolved solution, which was added to the filtered salt water in a ratio of ten to one. After a while, the three solutions began to neutralize, forming a milky white precipitate similar to "scale".
"Look, these white scales are the source of the astringent taste. There are so many of them."
A can of salt water has precipitated nearly half of the can of calcium sulfate, which shows how many impurities there are in the mineral salt.
The four poker brothers stood aside, looking at the chemical reaction they had never seen before, not to mention how shocked they were.
“I thought plant ash could only be used as fertilizer, but I didn’t expect it could also be used to make refined salt!”
"Actually, that's not the case. Plant ash has many uses. It can be used for cleaning, repelling insects, and making pottery... Oh, by the way, you can keep the unused quicklime today. I will teach you how to use it and plant ash to make a super good Delicious food – preserved eggs.”
"What is a preserved egg?"
"Preserved eggs are a kind of pickled product. They are made from raw eggs. They are sour in the mouth at first, and then leave an endless aftertaste. I guarantee you will fall in love with it after taking one bite, hehehe..."
During the chat, Song Che used plant ash and quicklime to precipitate salt water three times. When there was almost no reaction, it meant that the insoluble impurities in it had been removed.
Originally half a basin of salt water, now less than 80% is left. Then comes the final process, evaporation and crystallization.
Pour pure salt water into the pot, increase the heat to cook, and use a spatula to stir gradually. Leave these tasks to the four poker brothers.
Song Che found a piece of mutton from the kitchen, sharpened his chopsticks to make bamboo skewers, and made a few big lumps in one skewer. Then he found a smooth stone slab in the yard, washed it, built a simple stove, and placed the stone slab on the stove. Then he took out a few pieces of charcoal from the firewood stove——
He hasn't been able to eat a good bite in the two days he's been here. Tonight he will realize the freedom of mutton skewers!
"Zizzizi..."
Put the mutton skewers on the stone board and fry the meat in just a few moments.
"What are you doing? There is smoke everywhere at night."
At this time, Guo Shuyun and Zouping walked into the kitchen yard.
Song Che fanned the smoke with his sleeve, letting the fragrance fill the small courtyard. He greeted with a smile: "The two masters came at a really good time. Song is making slate mutton skewers. You are in luck tonight."
Zouping sniffed, "It smells really good..."
But Guo Shuyun frowned and asked loudly: "Where are Kangba and the others?"
The Six of Hearts ran out of the kitchen in disgrace: "Chief, are you calling me?"
Guo Shuyun frowned even more and scolded: "I sent you to keep an eye on him. Why are you all working in the kitchen? What if he escapes?"
"this……"
"It's done! It's done! Mr. Song, the refined salt has been refined! Look at it, how white it is!"
The Seven of Spades, holding a jar of white salt, ran out of the kitchen excitedly with the Four of Diamonds and the Five of Clubs.
Song Che casually picked up a handful and sprinkled it on the meat skewers. The aroma of the meat was sublimated again, and he couldn't help but salivate when he smelled it.
"My mutton skewers are also ready."
Song Che took a bite first. It was charred on the outside and tender on the inside, with just the right salty taste. The oily feeling in his mouth was simply wonderful.
He divided two bunches and handed them to Guo Shuyun and Zouping, and said with a smile: "Come on, can you two leaders try it too?"
Zouping was not polite. He took the mutton skewers, took a bite, chewed twice, widened his eyes, and said incoherently, "So... so delicious! I... I have grown up, and this is the first time I have eaten something so delicious." of mutton!”
Guo Shuyun turned a blind eye to the meat skewers. She bypassed Song Che and took the refined salt from the hands of the Seven of Spades. She was more skeptical than surprised, "When I was in Beiliang Mansion, the finest salt I saw was much thicker than this." , is this...really refined salt?"
Song Che smiled and said, "You will know after you try it. But I advise you to pick up less to avoid being salty."
With a questioning attitude, Guo Shuyun dipped a little of it with her finger and put it to the tip of her tongue to taste. The next moment, she exclaimed: "It's so salty!"
She looked at Song Che in shock: "How did you do it?"
Song Che handed the mutton skewers to her mouth and said with a smile: "After you eat it, I will tell you the method of refining coarse salt."
Guo Shuyun looked at the meat skewers, remained reserved for a long time, and finally took it. She felt energetic after taking one bite, but couldn't beat it away after taking two bites.
"The children's health is deteriorating, and the cause of the disease is in this coarse salt. I don't know where you bought this coarse salt. You don't even have the most basic cleaning of impurities. Adults can eat this coarse salt in their stomachs. Get through it, the kid will definitely suffer.”
Song Che handed the remaining mutton skewers to the four Poker brothers and said, "They have all seen the method of purifying coarse salt just now. Miss Guo can learn from them after we go down;
However, I still want to remind you that salt is necessary for daily life, and you should know its importance. Therefore, it is best not to let too many people know about this purification technology, so as not to cause unnecessary trouble. "
The way Guo Shuyun looked at Song Che had fundamentally changed.
Song Che took out the roll of paper from his sleeve, took off his brocade robe and handed it to her, and said: "These two pieces of paper have the "Three Character Classic" and the "Nine-Nine Multiplication Table" written on them respectively. Take it back and copy more. , as a textbook for children;
This brocade robe of mine is made of natural silk. It is perfect for filtering out impurities. Since it is already torn, I will give it to you. "
After that, he turned around and walked down the eaves, waving his hands and warning: "Don't forget that you will be a model tomorrow, remember to dress nicely, and breast enlargement exercises can enlarge your breasts..."
"Mr. Song... he doesn't look like a mortal, more like someone from heaven."
The Six of Hearts sighed sincerely, and moved away with the other three people, including the stove and meat skewers, and caught up with Song Che.
It wasn't until Song Che's back completely disappeared that Guo Shuyun slowly opened the scroll in her hand and chanted softly, "In the beginning, human beings are inherently good by nature, similar in nature, and distant in habits..."
After she finished reading, she kept shaking her head, "Impossible, impossible...why did he? And why? We are the ones who kidnapped him, how could he be so selfless? Who...is he?"
Zouping looked at the night sky and sighed softly: "Perhaps General Guo has a spirit in the sky and couldn't bear the last fire in Beiliang to be extinguished, so he sent him to assist us..."
