Outside the kitchen, the cold wind is gusting, the snow is full of snowflakes, but the kitchen is a hot scene, several coal stoves are sitting on a large cauldron, the cage drawer in the pot is placed a lot of bottles and cans, with the steaming of the hot air to emit bursts of food aroma, people can't help but breathe. Pen, fun, pavilion www. biquge。 info

"Are these what you call cans?" Princess Pingyang looked at the bottles and cans in the pot and asked curiously, after a few turns outside, Li Xiu took her to the house, saying that she would let her see a kind of food called canned, but now it seems that the so-called canned food is not magical, it seems that the food is just put in the jar and steamed for a while?

"Hehe, this is just a semi-finished product, and there will be some processing next." Li Xiu said and motioned to Yuechan next to him to continue, so he saw Yuechan take out a cork from another boiling pot, and then gently put it on the mouth of those jars, and then covered the pot lid and steamed violently, about half an hour later, Yuechan opened the lid of the pot, and then compacted the cork on the jar with a special thick wooden stick, and finally took out the jar.

"Okay, now these can be called cans!" Li Xiu smiled and put on a thick glove, and then picked up a jar to appreciate it carefully, but unfortunately there was no glass, so he used all ceramic jars, and he couldn't see the appearance of the food inside, it was not difficult to make cans, but it was difficult to find these ceramic jars, in order to find suitable and easy-to-seal ceramic jars, Li Xiu also went to Chang'an on a special trip, ran many ceramic shops, and finally found so many.

"But what's the use of it, isn't it just to put food in jars for easy access?" Princess Pingyang said with a confused face at this time, she really couldn't figure out what Li Xiu's intention was in doing this?

"Haha~, of course the role of canned food is not like this, the kitchen is too busy, let's not stand here in the way, Yuechan and they have to produce more canned food for experiments, let's go outside to talk!" Li Xiu smiled again when he heard this, and then walked out of the kitchen with Princess Pingyang.

At that moment, Li Xiu took Princess Pingyang to the front hall and sat down, at this time he was still holding a freshly made can in his hand, while the food in it was still hot, Li Xiu stuffed the cork on it, and then handed it to Princess Pingyang and said with a smile: "How does the princess taste this can, it is mutton made by Yuechan herself, it is delicious." ”

Seeing that Li Xiu was not in a hurry to explain the canned food, but let herself taste the taste of the canned food, this made Princess Pingyang a little anxious, but she was a very patient person, she took the canned food at the moment, and did not use chopsticks, directly picked up a piece of mutton with her fingers and put it in her mouth, and the result was that the mutton was fat and juicy, and it was really delicious.

"It's delicious, but can this can make the food delicious?" Princess Pingyang asked strangely again, it seems that if she doesn't understand the role of canned food, she will not be reconciled.

"Hehe, canned food is actually a way to preserve food, and it can't make food delicious, but it can keep the deliciousness of food a little longer, for example, the canned food that the princess eats now has this taste, and after storing it in a canned way, then after a month, two months, or even half a year to a year, its taste will still not change, and the food will not be rotten, as if it was just made." Li Xiu explained with a smile.

It is impossible for the original canned food made in such simple conditions as the tin cans in later generations to be able to be preserved for many years, but he is still confident that he can keep it for half a year to a year, and with this time as a buffer, he can transport the perishable food to the place where it is needed, which is the biggest role of canning.

"You...... Are you kidding, how can the mutton in the canned food last for half a year or a year, unless it is kept frozen in ice in winter, but it is so hot as summer, I am afraid that it will spoil and be inedible in a day or two. Princess Pingyang couldn't believe it when she heard this, Li Xiu's words once again broke her perception of the world, so she couldn't accept it for a while.

"The princess doesn't have to doubt it, this is the magic of canned food, the reason why the food will spoil **, one of them is because of something we can't see, you can see them as a kind of poison, just now I put the canned food in the pot and boiled it, just to eliminate this poison, and then seal it up, so that the poison from the outside world can't get in, and naturally it won't make the food inside change!" Li Xiu explained the principle of canned food in a language that Princess Pingyang could understand.

"How can food be poisonous? If the food we eat is poisonous, will it affect our body? Princess Pingyang understood Li Xiu's explanation, but soon had a second question, after all, she didn't know what a microorganism was.

"This ......" Li Xiu didn't know how to explain this matter for a while, if he started from the beginning, he didn't know if Princess Pingyang could accept the concept of microorganisms, and if she wanted to explain microorganisms clearly, she didn't know how much time it would take?

But at this moment, I suddenly saw Xiao Dong, who was guarding the door, running to report in a panic: "Master Qiqi, there are a lot of horses outside, and the old man is very unreasonable, so he directly pushed the door open and broke in!" ”

As soon as Xiao Dong's words fell, he saw a gray-haired and majestic-looking man striding into the hall, Li Xiu's first feeling when he saw the other party was that he was a little familiar, but before he could remember the identity of the other party, he saw Princess Pingyang stand up with a red face and salute: "Erchen greets my father!" ”

Hearing Princess Pingyang's words, Li Xiu finally remembered that during the Shangyuan Festival this year, he had seen each other in the princess's courtyard, this mighty man was His Majesty Li Yuan, the emperor of the Tang Dynasty, but he hadn't seen him for nearly a year, but he had a lot more white hair on his head, and he looked much older than before.

"Weichen see Your Majesty!" Li Xiu also hurriedly saluted at this time, but Xiao Dong next to her was almost frightened, just now she also called the other party a very unreasonable old man, but she didn't expect that he was His Majesty the Emperor of the Tang Dynasty.

Seeing Xiao Dong's frightened appearance, Li Xiu hurriedly pulled her and asked her to hide behind him, and then saluted Li Yuan again: "Just now, the subordinate didn't know Your Majesty's Long Yan and collided with the Holy Driver, and I hope Your Majesty won't blame you!" ”

"Hmph, I'm not so stingy, let's go down with everyone else!" I saw Li Yuan look around, and then waved his sleeves angrily, he braved the snow to find his daughter Pingyang, and wanted to talk to her well, but he didn't expect Pingyang to be picked up by Li Xiu first, making him pounce, which made Li Yuan also a little angry, and he came directly to Li Xiu's house at the moment.

Hearing Li Yuan's words, Li Xiu couldn't help but breathe a sigh of relief, and waved his hand to Xiao Dong who hadn't reacted yet, and the girl finally understood, and then trotted out of the living room, and then there were guards surrounding the living room, prohibiting anyone from entering.

"Pingyang, how are you doing lately, have you recovered from your old injuries?" After everyone retreated, Li Yuan smiled gently at Princess Pingyang, and then sat down by himself, but left Li Xiu, the master, aside.

"My daughter is very good, how can my father have time to go out of the city today, and it's still snowing outside, my father should take care of his body!" Princess Pingyang replied immediately, last time because of Chai Shao's incident, there was a little unpleasant quarrel between their father and daughter, but how can there be any deep hatred between father and daughter? Therefore, when Princess Pingyang saw Li Yuan again, she was also very concerned about his body.

"Hehe, fortunately, there is still Pingyang You care about your father's body, unlike your eldest brother and your second brother, who fight for your life and death for a little power all day long, and don't care about your father's feelings at all!" When Li Xiu said the end, his face also showed a little annoyed, and after seeing his daughter's filial appearance, he became even more angry with Li Jiancheng and Li Shimin.

Li Xiu secretly pursed his lips when he heard this, and he was quite disappreciative of Li Yuan's words, the reason why Li Jiancheng and Li Shimin fought like this was not because Li Yuan didn't handle it well? It can even be said that the root cause of this matter is Li Yuan, but now that he blames his two sons, he will really shirk his responsibility.

"The eldest brother and the second brother also have their own hardships and ideas, and the father should not be too angry with them." Princess Pingyang opened her mouth again at this time to persuade, but she couldn't express any opinion on this matter, because no matter which one she preferred, she would feel ashamed of the other, from this point of view, she and Li Yuan were in the same situation, no wonder Li Yuan would come to her to confide, because only Princess Pingyang could better understand his dilemma.

"Alas, now that your eldest brother and second brother are in trouble like this, I really miss your mother, if she is still alive, I'm afraid I won't need to be so embarrassed!" Li Yuan confided in his daughter again, but as for Li Xiu next to him, he was regarded as a transparent person, or he didn't care that Li Xiu heard these words.

Hearing her father mention her mother, Princess Pingyang couldn't help but show a sad look, but people can't be resurrected after death, and as a daughter, she feels the need to share her father's worries, so she finally gritted her teeth and said: "Father doesn't have to be too embarrassed, if it really doesn't work, it's better for her daughter to come forward and persuade the eldest brother and second brother, lest they make too much trouble." ”

As Princess Pingyang, who has never interfered in the fight between the two brothers, being able to say the above words can be regarded as a huge sacrifice, but Li Yuan shook after hearing this, and then looked at Princess Pingyang with some doting and said: "No need, you are in the same situation as your father, and you have always ignored this matter, so don't get involved!" ”

Li Yuan didn't want Princess Pingyang to say anything more when he said this, so he changed the topic with a smile and said: "Pingyang, you don't stay at home on such a cold day, what are you doing when you run out, what if you get frostbite?" (To be continued.) )8
