Qi Cheng and his wife are both real people, the tables and chairs are in place, and Qi Cheng can already knead the dough and bake the baked cakes by himself. Ye Xinyan taught Li to make rice tofu and corn stalls, Li is a woman who works in an ordinary farmhouse, and she is not unfamiliar with these stove things, and she is also very easy to learn.

Greeting guests, as long as you pay attention, you can get started faster, and the two gradually get acquainted.

With these two strong laborers joining, Ye Xinyan and Qi Younian felt a lot more relaxed. Ye Xinyan privately discussed with Mama Jin and Qi Younian whether to raise their salaries.

Mama Jin has seen a lot of money, and she won't care about these things, of course, Qi Younian also nodded in agreement, but just made a suggestion, and when the whole month is settled, the income is good, and the salary can be raised justifiably.

That's what benefit pay means. Ye Xinyan was secretly amused, it turned out that the productive forces had developed for thousands of years, but there was no major change in human nature, and the reward mechanism of the ancients was also like this.

Ye Xinyan had some leisure, so she planned to make ice drinks, she didn't have those powerful golden finger skills, she only planned to use pure calorie exchange to make ice cream.

She used to hear from the elders of the previous generation that when there was a serious shortage of materials and there was no large-scale modern catering enterprise, small local business establishments used salt and ice cubes stored in ice cellars to make popsicles and sorbets.

At that time, there was no dazzling variety of ice cream and ice cream, and a few pennies of a popsicle could satisfy the children in the middle of summer.

Sorbet, on the other hand, is a more high-end ice drink than popsicles, with more milk and egg yolks.

The appearance of sorbet in the summer of this era should be a rare and high-profit business, which can take the high-end route.

Ye Xinyan has already thought about it, and rented a small shop next to the largest restaurant in the county, which is beautifully decorated. In the beginning, I mainly delivered cold drinks and snacks to restaurants. When the guests of the restaurant need it, they serve it to the diners of the restaurant from their own small shop in the way of serving food.

The profits from the sale of cold drinks and snacks are shared with the restaurant. There is the largest restaurant that advertises her small shop, and it doesn't take much effort to make the transaction high-end.

If you can make ice cream, that's ideal. However, extracting whipped cream or cream was too difficult for this era, when there were no dedicated cows, calve-giving cows had a low milk yield, and there were no cows.

So she had to settle for the next best thing and make the sorbet that the village elders had said. She will do her best to make the sorbet delicate, reduce the ice residue in it, and strive to make the sorbet close to the taste of ice cream.

If you can successfully make the sorbet, it will be able to sell well for more than a month while it is still midsummer. Even after the summer season, sorbet is attractive to the pampered wealthy. Even in the middle of winter, as long as the warm facilities of restaurants and wealthy homes are good, there are also requirements for sorbet.

Ye Xinyan estimated that if the transaction went well, he would be able to accumulate a lot of silver in two months. In autumn and winter, you can expand the scope of dessert shops and make more casual snacks. In addition to a variety of desserts, you can also make some soups and a variety of delicate snacks.

If the grandfather did not want to leave the village, he would use the money he earned to buy some fields, build new houses in the village, and give up the fields. In this way, the life of their family of four will be completely stable.

Fields and real estate are fixed assets. Especially in the fields, in ancient times, as long as there was enough land and enough grain storage, it was the greatest foundation for people's life to be stable and prosperous.

Just do what she said, Ye Xinyan used her leisure time to inquire which family had cows to give calves and where to sell ice cubes. Then prepare cornmeal, eggs, and other ingredients for sorbet. After three or four days, the preparations are ready.

On this day, Ye Xinyan went to buy a small can of milk first. Then I went to buy ice cubes and wrapped them in layers of tarpaulin, wooden boxes, and quilts.

After the rice tofu stall went home, Ye Xinyan didn't even help Mama Jin make lunch, and began to try making sorbet.

She first boiled the milk, waited for the milk to cool a little, and then mixed the ultra-fine corn flour, sugar, and egg yolk prepared in advance into the milk, cooked it again, and boiled it into a paste, stirring intermittently, while waiting for the milk paste to cool.

Then comes the key part of the sorbet. Pour the cooled milk paste into a small, thin-skinned tin bucket and place the bucket into a larger wooden bucket. In the sandwich of wooden and iron barrels, crushed ice cubes and coarse salt grains are put into the sandwich.

Then you need to keep the barrel as cold as possible. Wrap the wooden barrel in layers with quilts and cotton wool, and then patiently wait for the cold energy transfer between the milk paste and the ice cubes to let the milk paste freeze. The milk paste freezes for a long time, during which time the ice cream should be vigorously stirred several times to reduce the ice residue during the freezing process.

After this dazzling busyness, when Ye Xinyan uncovered the lid on the wooden barrel and the ice cream in the small bucket was a little cool, it was already after taking a nap.

The ice bucket was placed on the stove in the outer room that was idle in the summer, and the other three people in the family were almost dumbfounded when they saw the cold ice cream.

Qi Younian was even more stunned, the milk paste in the thin iron bucket was actually frozen, just like something frozen in the cold winter season.

It took him a long time before he opened his mouth and asked, "This, how did you freeze this thing into ice in the middle of summer?" ”

Ye Xinyan claimed to make a snack that made more money than rice tofu, and Qi Younian was curious, so he watched the whole process.

He watched Ye Xinyan use milk, egg yolks, corn flour, sugar and other substances to make a paste and pour it into a small bucket. Then the crushed ice cubes and salt were mixed and poured into the sandwich of wooden and iron barrels, covered with a lid, and wrapped around a thick quilt.

Ye Xinyan didn't say that he wanted to make ice cream that could be frozen, and Qi Younian would not have thought that after such treatment, he would be able to freeze the milk paste into ice-like food.

Because Qi Younian didn't know what kind of food Ye Xinyan would make in the end, he still regretted that this snack was really labor-intensive, if it was so time-consuming, even if it was made, it might not be as convenient and profitable as it was set up earlier.

As a result, this Nizi actually made such a rebellious thing. It's the height of summer, it's so hot that it's almost smoking, and the leaves are frozen for food.

Qi Younian was puzzled, and then looked at the interlayer where the crushed ice was placed, and now the ice in the interlayer has melted into water, why is the original milk paste turned into ice? So, how are these two different states exchanged?

Qi Younian pointed to the wooden barrel and stammered, "This, this is water, right?" How can you freeze something that was originally slimy? ”

Ye Xinyan blinked, she couldn't explain to this ancient grandfather, the physical characteristics of salt water, and the relationship curve between salt water concentration and freezing point, right?

She looked at Mama Jin again, and Mama Jin also looked at her with wide eyes, waiting for her to solve her puzzles.

"That, grandpa, I also came up with it by chance. Just like in winter, salt water doesn't freeze, you know that, right? Don't understand? Pickle tank, let's pickle pickles, no matter how cold the weather is in winter, the salt water in the pickle tank will not freeze, right? Ye Xinyan explained.
