Jin Rong asked directly, and Qi Younian replied happily: "Back to the sixth master's words, the little old man doesn't dare to deceive the little brother Hongzhi, and the shopkeeper Hao of Honghelou also knows that the ice cream is really frozen with ice cubes." The ice we use today was bought with the help of Shopkeeper Hao. ”

Qi Younian thought, since he didn't tell Hongzhi everything just now, and now it's not good to say it like a bamboo tube pouring beans, he can only tell Jinrong like this.

"Take me around."

Qi Younian simply took out a neatly wrapped wooden barrel this time and lifted the lid. The outermost layer of insulated cotton cover, then the wooden barrel, the mezzanine, the small tin bucket, and the innermost creamy yellow sorbet, all of which are clear at a glance.

Jin Rong looked at it for a moment, glanced at Jiang Yifan, pointed to the ice water in the mezzanine, and asked, "The ice cubes in this interlayer have melted into water, but the ice cream is still frozen firm, what's going on?" ”

Qi Younian replied calmly: "Back to the sixth master, salt has been added to it." ”

Jin Rong didn't show a puzzled look, and even the moment Qi Younian said the salt, Jin Rong thought of the key.

In the middle of winter a few years ago, he had accompanied the mission to Beiyi, and saw a lake in the hinterland of Beiyi. At that time, Beiyi was full of ice and snow, and the wind was cold, but the lake did not freeze.

Jinrong also had doubts at the time, and officials in Beiyi explained that it was a salt lake, and even in the middle of winter, when the temperature was extremely low, there would only be some ice flowers, but it would not freeze.

Jin Rong glanced at Jiang Yifan again, and asked Qi Younian: "Listen to the old man's meaning, this is also the method that the old man's granddaughter thought of?" I wonder how she figured out that this would freeze the food? ”

It's not that he insists on getting to the bottom of the Qi family's old man and Ye Xinyan, but there are too many accidents like this, so it's not a coincidence or coincidence.

Qi Younian looked at the thick doubt in Jinrong's eyes, and couldn't help but shudder in his heart, and replied carefully: "We countrymen all know the salt soup of pickled vegetables, no matter how cold the weather is, the salt soup will not freeze. But the only one who thought of making sorbet with this principle was my granddaughter. It is also a blessing for the little old man to have such a smart and clever granddaughter. ”

Pickles......? How simple is that? Jinrong glared at Qi Younian in disbelief for a long time, and stared at Qi Younian until his forehead was sweating, and then he retracted his gaze very unwillingly and stupidly.

It's that simple, just such a simple reason, that the woman of the Ye family can make a frozen snack in the middle of summer. And this woman is still a well-known reckless and brainless lady in the capital, how can such a result make those smart and talented women in the capital embarrassed?

Jiang Yifan on the side didn't know the joints, especially when he was glanced at by Jinrong meaningfully, he didn't understand. He asked, "What's going on?" Does this sorbet still have anything to do with pickles? ”

As soon as the signs of suspicion in Jinrong's heart rose, he was ruthlessly destroyed by Qi Younian, and it was the time when he was full of depression.

Hearing Jiang Yifan's question, Jinrong said angrily: "I don't know if it has anything to do with pickles." It's just that I have seen the salt lake in the hinterland of Beiyi in the middle of winter, and the lake with a high salt content will not freeze even in the severe winter of ice and snow. ”

Jiang Yifan still didn't quite understand, he turned his gaze to Qi Younian.

Qi Younian explained: "Ordinary ice cubes will melt when placed in the sandwich of two buckets, but that kind of melting is our common water, and we will never make ice cream." If salt is added, the ice melts faster, but the melting brine is much cooler than normal ice water. If you keep putting ice cubes and salt in it and keep it warm, you can freeze the sorbet paste with this flowing low-temperature brine. ”

This is Ye Xinyan's explanation to Qi Younian, although it is not comprehensive enough, it can only be explained in this way. Ye Xinyan himself does not have authoritative theoretical knowledge in this area, and he really does not have the ability to explain this physical process to the ancients in simple terms. Moreover, even if she has very professional theoretical knowledge, I am afraid that Qi Younian and others will not understand it.

Fortunately, Jiang Yifan basically understood, even if there were details that he couldn't figure out, it was inconvenient to ask more at this time.

Jin Rong was happy to see Jiang Yifan embarrassed, and asked with a sneer: "Have you never seen people pickle vegetables?" ”

Jiang Yifan gave Jin Rong a roll of his eyes: "Who has trained children who have been studying since childhood to learn pickles?" Have you ever pickled pickles? ”

"Hmph, at least I've seen the salt lake, have you seen it?" Jin Rong argued forcefully, turned his head to look at this aggrieved place, and thought that it was the eldest lady of the Anguo Mansion who used to show off her martial arts and prestige to see the storefront, and then thought of the miserable comments of the eldest lady of the Ye family in the capital, and suddenly had other thoughts in her heart.

"Old man Qi, let's feel it, this business of your family is really not easy to make it like it is now. It's all good food, and the décor on the outside of your little shop is chic, and the name of the shop is good. But you see, you've made it like this. ”

Jin Rong casually snorted, "The store is so small, which nobleman is willing to eat with people?" And the decoration of your shop, especially those paintings, those things...... It's a painting, right? I think it can enter the eyes of a three-year-old child, only a little childlike, but there is no elegant connotation. ”

Qi Younian couldn't help but smile bitterly, these things, his family Ye Zi had already deeply self-examined. She also turned a store that she thought was high-end into a snack shop that entertained half-sized children and children, only to realize that she underestimated the consumption grade and cultural literacy of the rich.

Her cloth stickers and dry branches and bottles were not actually recognized by the vast number of wealthy people in Qinghe County. As Jinrong said, these things can only show childlike fun, which is probably what children will appreciate.

And the adults cultivated by ancient families, one is due to their own literacy, and they will not be interested in these things that have no connotation. Again, in the face of harsh competition between families and brothers, these people will never be nostalgic for their childhood, showing their interest in childish and childlike things.

And this storefront is indeed cramped, and it is difficult to accommodate people with status.

"This ......, we were originally a small business, and we really can't make the scale you say. Now the situation is very good, the business of the small shop is not bad, and there is a lot of profit. Although most of the diners patronize are children, they are all children from wealthy families, and they are generous, and the little old man and his family are quite satisfied with the income of the small shop. ”

Jinrong understood what Qi Younian meant, but did not agree with Qi Younian's statement.

If it was just Qi Younian himself, he would have had many ups and downs in his life, and he had never enjoyed much wealth, so there was nothing wrong with thinking so. But for the granddaughter of An Guogong, who escaped from the capital and once enjoyed a luxurious life, the word "willing to be poor" could not appear in her cognition at all.

Jinrong moved her eyes to the direction of the store, judging from the decoration of this small shop and the types and prices of food, Ye Xinyan's initial plan was definitely to do the business of the rich, but things did not develop in the direction she wanted.
