Yu Wuya also sewed two pockets on his clothes, bulging with fried soybeans, squatting next to him from time to time pinching a few grains and putting them in his mouth to chew, and then watching Chen Xu soak half a pot of dried and ground soybeans in a clay pot.

"Engong, when will you eat the stinky tofu you said, Wuya can't wait, what kind of novel taste will the smelly and delicious food be!"

"I haven't been able to eat it recently, because there is no salt brine or gypsum, and the bean juice can't be condensed and formed, so I can only drink soy milk for the time being!" Chen Xu said helplessly.

"What is plaster? Is salt brine just salt? When Yu Wuya heard the word salt, he immediately thought that the two were similar things.

But Chen Xu was depressed, yes, chemically speaking, all compounds formed by metals and acids can be called salt, but this salt is not the other salt, magnesium chloride and calcium sulfate can also be called salt, but it is completely different from the sodium chloride that is flavored, sodium chloride is salty, but magnesium chloride and calcium sulfate are bitter, but now it is not clear to the ancients about these things, and if these three things are placed together in front of them, they are not very clear.

It seems that in order to eat delicious stinky tofu safely, you have to get a simple set of chemical experiment equipment, otherwise you will get a lump of arsenic as salt and eat it one day.

"Salt brine and gypsum are bitter, not salty......" Chen Xu still briefly explained, the taste of the two is different.

"Isn't the spring water in the cave where you store your wine also bitter, could it be salt brine or gypsum water?" Yu Wuya hurriedly asked.

"Hey, you've reminded me!" Wake up the person in the dream with a word, Chen Xu immediately stood up happily and said, "Let's go, let's go get some and try it back!" ”

"Come and go for dozens of miles, Engong doesn't have to go, my horse is fast, I'll go and get it!" Yu Wuya was even more excited, and he didn't eat the soybeans anymore, untied the horse's reins from under the pergola and turned over on the horse.

"Remember to collect some of the white powder in the cave and bring it back~" Chen Xu hurriedly said loudly.

"Okay~" When Yu Wuya spoke, he waved the horsewhip and snapped a few times, and then ran away in a blink of an eye.

Chen Xu: ......

Nima is really a foodie, but it's good that you don't have to run back and forth.

"Where is Boundless going?" Chen Jiang came out of the room and asked.

"Oh, he's going to town to help me find something to make tofu!" Chen Xu said.

"It's been a long time since I've seen the water girl, do you want to go to Wancheng to visit?" Chen Jiang likes the gentle and beautiful water very much, and also knows that the relationship between the two is relatively close, although he doesn't know that the two of them are almost cooked rice, but they haven't seen each other for a month or two, and they are very worried.

"Don't worry, when the autumn harvest tax and grain are almost busy, I will go to Wancheng with Wuya to visit, and I can also pick her up to live with us in winter!" Chen Xu hurriedly said.

"Really, don't cheat on your mother!" Chen Jiang said with a happy face.

"Sister Water is here?" Xing'er was in the room, and after listening to half of the words, she quickly ran out to ask.

Chen Xu shook his head and said with a smile: "Xing'er, would you like to be your sister-in-law if Sister Shui was your sister-in-law?" ”

"Yes, brother, are you planning to marry Sister Shui? That way, I can play with Sister Shui every day, and she can sleep with me at night! Apricot clapped her hands excitedly.

Chen Xu: ......

"What nonsense are you talking about, if my brother marries Sister Shui, of course Sister Shui will sleep with my brother!" Chen Jiang blushed and slapped Xing'er's little buttocks.

"Why, son, how can a woman sleep with a man?" Apricot asked puzzled.

Chen Xu: ......

"When you grow up and marry Brother Dashi, you don't want to sleep with him yet!" Although Chen Jiang feels that this topic is a little difficult to talk about, as a mother, she still has to instill some ethical relationships between male and female couples in her daughter, otherwise it will not be good to make jokes when the time comes.

"Hey, I'm not going to sleep with Brother Dashi, shame, I'm going to sleep with Sister Shui!" Apricot yelled loudly.

Chen Xu twitched a few times and sighed silently, and instructed Chen Jiang to help make a cloth bag out of the finest linen, and then turned around to cut bamboo, and to filter the bean juice, he had to prepare a bamboo frame.

Yu Wuya's speed was very fast, and he only came and went for an hour, and not long after Chen Xu finished the bamboo frame, he came back, and there was a rattan basket hanging on the horse's back, and a large clay pot was placed in it.

"Engong, the bitter water has been retrieved, how can you get it?" Yu Wuya didn't feel the fatigue of running back and forth at all, and asked excitedly holding the big crockpot on the ground.

"Did you get the white powder?" Chen Xu hurriedly asked.

"Got it, here!" Yu Wuya turned around and took out a bamboo tube in the rattan basket, in which were placed a small half-tube of white powder crystals, mixed with a lot of damp sand and mud.

Chen Xu dipped his hand a little to the tip of his nose and was about to smell it, but Yu Wuya hurriedly said: "Don't taste it, Engong, it's extremely bitter and hard to swallow!" ”

"You tasted it?" Chen Xu asked in surprise with a face.

"Well, the last time I went to get wine, I heard Engong say it was bitter, and Wuya didn't believe it, but today I tasted it curiously, and it was really bitter!" Yu Wuya nodded and said.

Nima is a second goods, and those who don't know dare to put it in their mouths, but they are relieved to think about it, in this primitive era, everything can only be recognized by their own personal feelings, otherwise Shennong's family will not taste the herbs, and as a disciple of Liezi, Yu Wuya learned the art of Huang Lao, and has a very practical spirit of scientific research.

Chen Xu took a look at the soaked soybeans and found that because they had been ground with a stone mill in advance, they had been soaked for more than two hours, and they were almost ready to be ground into a pulp, so after Yu Wuya drank water and rested for a while, the two began to grind and feed one by one, and it only took half an hour to grind all the small half pot of soybeans, and then put all the soybean milk into the fine linen bag that Chen Jiang had already sewn and cleaned, and put the freshly made bamboo frame on the big tile basin, and began to pinch and press the bag tightly after tying it tightly.

"Hey, Engong's filtering method is novel!" Yu Wuya began to marvel at Chen Xu's simple and novel invention again.

"Wow, there's a lot of milk coming out of the baggage, I want to drink milk!" Apricot clapped her hands excitedly.

"Don't talk nonsense!" Chen Jiangshi blushed and quickly covered Xing'er's mouth.

"This is called bean juice, it's not milk, you can't drink it raw, and when my brother cooks it, I put some honey on it!" Chen Xu also hurriedly explained, lest this girl go all over the village after a while and shout that her brother will pinch the beans out of the milk and make it bigger.

After squeezing it for 20 minutes, I got half a pot of soy milk and half a pocket of half-dried okara, but now I can barely express milk...... Well, the bean juice was gone, so Chen Xu didn't bother to continue to work hard, put the bean dregs and pockets aside, and then poured the bean juice into a washed clay pot and put it on the earthen stove, and let the apricots cook on the fire.

Seeing Chen Xu turn around and go to get half a pocket of bean dregs, Yu Wuya asked curiously: "Engong, can this remaining dross also be used?" ”

"This is called tofu dregs, and it is also a delicious dish when it is done, today I will make you a scallion bean dregs cake, which is fragrant and crispy, especially delicious!"

"Hey, Engong hurry up, my saliva is falling!" Yu Wuya's foodie nature was fully revealed, as long as Chen Xu said a word of food, he would reflexively start to salivate in his mouth.

Taking advantage of the gap between apricots cooking soy milk, Chen Xu went out for a spin and picked a handful of wild onions and some tender alfalfa vegetables.

Because it has been autumn for nearly a month, all kinds of plants in the mountains and fields have grown old and begun to drop seeds, wild vegetables are even more so, whether it is wild onions and garlic are sturdy, even the shepherd's cabbage, celery, and mother-in-law that can be eaten on weekdays are old, and the wind blows all over the sky are flying dandelion umbrellas, and the leaves are naturally not edible, he searched for a long time in the shade of the ditch, and finally found some wild onions and alfalfa that look quite tender.

Alfalfa is an ancient vegetable in China, with high nutritional value, and also has good medicinal value, which can treat stomach ulcers and hemorrhoids, but the taste is not as good as shepherd's cabbage and mother-in-law, so few people eat it, but now the fresh and tender wild vegetables are gone, and it is still a good choice to chop some tender alfalfa and mix it in the bean dregs cake.

Winter is coming!

Chen Xu was a little emotional, and he was also very depressed.

Once he waits until winter, I am afraid that there will be fewer and fewer green wild vegetables to eat in the mountains and fields, so when he washed and chopped vegetables, he asked Chen Jiang: "Mother, do we have any vegetable seeds that can be planted in winter?" ”

"Originally, there were some wead and reed seeds, but I dug a small vegetable garden behind the house a few days ago to plant them, and found that the seeds were all moth-eaten and rotten, and they were still planted three years ago, and I don't know if they can germinate in the ground!" Chen Jiang shook his head and said.

Well, Chen Xuleng turned his head to look at Yu Wuya for a long time: "What kind of vegetables are weeds and reeds?" ”

Yu Wuya also asked blankly for a long time: "Engong hasn't even seen these two dishes?" ”

"Uncle Yu, my brother fell from a tree and broke his head, and he can't remember the previous ones!" Apricot explained on the side.

"Oh, I'm sorry, I'm sorry, don't blame, Wu Ya didn't think about it for a while, woad is a kind of large-leaf green vegetable, the taste is bland, but it is cold-resistant, not delicious, and it will sprout and bloom in spring, it looks a bit like the root of the banyan, but it is seven or eight times larger than the root of the banyan, and it grows up to a foot square!" Although Yu Wuya expressed it very clearly, Chen Xu still didn't remember what kind of vegetable the enlarged version of Banlan root was.

"What about the reeds?"

"The reed is similar to the mustard gnocchi, the green leaves on it, the young leaves are edible, and there are a little burrs when they are old, but the roots are the size of a fist, the green skin and red skin are all there, the taste is spicy, and it can be made into pickles after being diced and dried......"
