Niu Shijin made the beauty of ***, and it is in line with the appetite of Datang people, many people who come to the amusement area, claiming that in order to eat, they will come again.

It's a pity that the royal family won't have a chance to eat it, unless they come to the Fan family manor again.

Of course, if the ladies come to the Fan family manor again, Fan Jingjing will still give an area for the ladies to stay, and they can't mix with other people, unless they wrap up the Fan family manor recreation area and hold the activities of the monarch and the minister's fun party, after all, the emperor sometimes has to have some dealings with some nobles.

There are a number of restaurants in the play area, some selling pastries, some selling drinks, some selling hot snacks, and some where you can sit and enjoy the view.

Fan Jingjing has also launched a lot of snacks, such as fried buns, cabbage buns, meat buns, and even fish buns, and the price is not expensive.

Fan Jingjing has promoted pork and fish.

At the same time, there are restaurants for ordinary people, as well as middle and high-end restaurants.

Datang is a society with great differences in social hierarchy, and Fan Jingjing does not dare to mix together.

The play area is ongoing, and the obstacles encountered by the glass are also present.

Glass sealing is a big problem.

Unlike pottery, pottery only extends the shelf life slightly, and the food in the glass needs to be stored for a month to half a year, and the sealing problem is more important.

Fan Jingjing gave the idea of threading, and asked the iron factory to study the machinery for making standard threads.

If the glass bottle is covered with glass, it is not conducive to preservation.

And the glass bottle can't be too much, it's best to solve the ingredients inside in one day.

Plastic is very easy to use, it is very polluting, and it can be of great help to sealing, and Fan Jingjing does not want to develop plastic.

Even if there are environmentally friendly plastics on the market, they are not really environmentally friendly.

Now replacing the packaging with tree industry hemp rope, Fan Jingjing looks good.

In the eyes of the Tang people, it is daily, and in her eyes, it is the ancient style.

In Fan Jingjing's impression, making threads was not too difficult, however, Fan Jingjing was slapped in the face.

In the era of handicraft, standardization is the most difficult thing.

The most difficult thing is that the thread, if you want to fit, you must have a mechanical process, or if you want to hire someone to build it, you must have a very high skill to get exactly the same.

Ordinary people can't do it, they have to rely on old craftsmen.

The old craftsman is too old to make a few pieces a day.

The work that requires skills will increase the cost, and Fan Jingjing attaches great importance to the cost.

Only at low cost can it be manufactured in large quantities.

Even in Datang, if he wants to reduce costs, he knows that if he wants to make these integrated things appear, he must have lathes and mechanical equipment.

He didn't expect to make such a big thing with a can.

Now at the beginning of the period to be able to settle for the second, even to put the glass cans, and then to develop the first to develop the ceramic cans.

But the study of the sealing cap must be carried out. There has to be another way.

Then Fan Jingjing suddenly thought, in fact, she seemed to think wrong, in addition to mechanical equipment, it seems that the sealing lid can also be made of cork, oak is a good material, didn't many red wines use oak to plug the lid in the past?

Only a unique piece of equipment is needed to open the cork lid.

The problem is that if you plug the lid like this, if you don't want to waste wood, you have to make the lid a little narrower to achieve the sealing effect.

Suddenly, Fan Jingjing thought that in fact, wood is not so expensive, because now it is not the future generations, but the Tang Dynasty.

Just trying to find oak doesn't seem to be that simple.

"That's not right!"

Fan Jingjing clapped her hands. I feel that I am confused by the name, but in fact, the oak tree is not difficult to find in Datang, but the name is different.

Oak cork, including oak and oak, is suitable for growing in temperate periods.

It may be that in the woods of the Fan family manor owned by Fan Jingjing, there will be these tree species, and these tree species are considered native tree species.

Thinking of a solution, Fan Jingjing went to find it with the researchers.

The research staff immediately arranged for people to go to the mountain to find trees, and arranged to cut down trees, after all, if you want to cut trees in the Fan family manor, you can't cut them arbitrarily, they must be reviewed.

And when cutting down trees, you can't cut them in a row, there must be an interval so that you don't damage the water and soil.

Fan Jingjing knew that before the Tang Dynasty, Guanzhong was a good place, but after the Tang Dynasty, this place in Guanzhong was almost destroyed, and the main reason was because of poor soil and water conservation.

After the Loess Plateau was deprived of vegetation, the soil of the entire plateau could not contain water, and then slowly this place became drier and drier, and the rainy places moved to other places.

With the method, it was not too difficult to cut down the tree, and soon they made the oak tree about the size of the mouth of the bottle.

Woodworking tools are the most improved tools under the promotion of the tools brought by Fan Jingjing.

Many of them have been copied successfully, and those that have not been copied successfully have also made a simplified version.

In the end, they figured out how to achieve the best airtight size, but not too small, so that people's chopsticks can clip the meat out, and more importantly, be able to put the meat in.

The same thing can be placed on top of a clay pot.

Fan Jingjing is also very happy to be able to develop the canned thing so quickly, in fact, the most important thing to make canned food is to blow glass, but if you want to reach an agreement, the same size, and the same appearance, it is the biggest difficulty.

At this stage, it is still mainly manual.

Anyway, people in this era do not have the concept of the same size.

The process of blowing glass is relatively simple, so they quickly studied it when they were researching, and the iron workshop also provided great help.

That's for later.

"Now it's time to start experimenting." Fan Jingjing said.

The fish will be ** in two or three days. Tofu will turn bad in a day.

Fan Jingjing asked them to use these two things. It's easy to experiment with tofu because they buy a bunch of soybeans and a bunch of soybeans in the middle.

When Fan Jingjing grows things, she doesn't have to be like ordinary farmers, she can wait for one after another, but different crops, if a field is harvested, it will be replaced with another crop to plant, and it will not be planted on the same land.

In this way, different nutrients can be absorbed, and at the same time, the same nutrients cannot be released.

The people of Fan's Manor like to use the beans grown by Fan's Manor themselves to have some tofu, which is particularly delicious and sweet.

When there are no worries about their economic life, eating something good has become their daily life.

After all, most of them were lonely when they came to the Fan Family Manor, and there were no children or elderly people to support, and such people were often able to live the most exquisite and best life.

On this day, the Fan family manor recreation area, as well as the shops in Fan family town, all appeared with ceramics and glass jars.

It's full of fish, but the fish in the ceramic jar is relatively simple, and the glass jar is a fish with a better taste, such as sea bass and anchovies.

If you want to go to the beach to catch yellow croaker, Fan Jingjing is still investing in shipbuilding, and the boat will not be built in a few months.

Fan Jingjing also wants to make steel ships, but she knows that the current steel ships do not have anti-rust devices, and they will rust faster in the sea than in the water, because the sea water is salt water.

Food in clay pots is more expensive than regular food. Clay pots are originally expensive products, but the small clay pots and small glass jars in Fan's manor are cheaper than the clay pots or glass jars in other workshops.

Even if the food is not tasty, you have to take a bite.

Canned food is not a raw ingredient, but a cooked ingredient, and the cooking method is naturally developed by Niu Shijin.

It can be regarded as Niu Shijin's contribution.

To be honest, Fan Jingjing thinks that Niu Shijin should not be a general, but a chef, and he always has new ideas in food, which can be regarded as his talent!

Fan Jingjing let Niu Sijin play freely, after all, he had already handed over so many recipes that had been lost, and he should give Niu Silk Scarf a room to play, but he didn't expect that the canned food he made was listening to Fan Jingjing. After that, it can be so delicious.

Don't know about the materials. It's going to get tastier, or that's it. Slowly it becomes unpalatable. Half a pound of gold doesn't have much time to do. Half of the cans he made in the experiment. Half of it is put into storage and sold for sale, after all. There are very few pieces of meat that can be cooked cold, and each canned food is small. But it can be stored for a long time, so it can be. When the undertaker is in his hands, not to mention the delicious food, Fang Jingjing also sat next to him for a little. They only let them taste it.

Canned meat, with a lot of oil and water, is also particularly delicious.

In May, the lychees on the trees began to grow, and the lychees, which had taken several years to grow, bore fruit.

Fortunately, Fan Jingjing was sprinkled in the mountains, and people didn't know that this was a lychee newly planted by Fan Jingjing.

The lychees planted by Fan Jingjing have various varieties of lychees, some of which start at the end of May, and some of them need to bear fruit in August, which can make Fan Jingjing have lychees to eat for a long time, and Fan Jingjing is a girl who likes to eat lychees very much.

The tasting plate is made of lotus leaves, and the aroma enters the tasting dish, and I often want to eat it again after eating.

If it's a large jar of meat. People will feel a little more expensive.

But a can of food is only three pennies, and the amount of meat is also a small bite.

The main thing is that when the cans are opened, they have to be eaten up.

The person who bought it thought in his heart that there was something to celebrate, so he needed to open the can, and it could be stored for ten days and half a month, and it was convenient to go out.

On the road, it is often difficult to eat.

If it's an ordinary family, forget it, the rich and noble can't bear this hardship.

For the sale of canned food, Fan Jingjing's test was only done for ten days.

Other experiments are ongoing.

On the first day, Fan Jingjing prepared seven hundred and thirty cans.

Each day you can open a test can and the number of days you can save it.

As for the canned food sold in the store, it is all new, and there are 100 cans on the shelves every day, and when half of them are sold, they will be cooked.

When the sales volume is large in the future, it will be expanded.

After all, it is not clear to them how long canned food will stay fresh.

Each can is tested separately until the next few days

The shelf life will be marked until the first few days.

Except for the sealing problems, the deadline has not yet arrived.

It was not ordinary people who tasted it, but white mice.

Of course, after Fan Jingjing determines the final experimental date, she will halve the date as a guarantee, and there will be no problem in eating more than one or two days.

It's really been more than a long time, and people don't dare to eat it.

Most people buy canned food to give away, and they feel that they can't make these flavors, and the meat that can be eaten directly is indeed very convenient, and some people who often work outside also want to eat some dishes, but they feel very expensive.

However, it is not cost-effective to buy vegetables if you buy them, many people's vegetables are sent from the countryside, and even if you buy vegetables, it doesn't cost much, because there are too many people who grow vegetables nearby, so the price of vegetables can't go up.

"We not only researched these dishes, but also canned food, the most important thing is actually to make canned fruits, everyone needs sweets, if there is no sweets, the body will be broken, but if you want to send the sweets from the south, it is easy to spoil, so we want to study canned food, but glass boxes, although ceramics are very well fixed, but there is still a big problem in transportation, that is, it is easy to break, so we must also study what can be transported."

Fan Jingjing also wants to study iron cans according to the size of the can, but the iron cans can be reused, and the glass cans are stuck in it, and then they will not sway when they are transported, and they can be transported very well, but these things are made when they are manufactured. They must be sent to the place of origin.

Fan Jingjing found that what problem would get stuck in her in the end was the transportation problem.

Fan Jingjing decided to develop into the ocean.

She knows that these pottery and glass cans will not be thrown away directly by the Tang people, but will still be recycled, and can become good containers and utensils at home, which have more uses than ceramic pens and bamboo utensils.

Fan Jingjing actually has a headache.

She found that if she wants to do a good job, it is equivalent to rolling a lot of things together, and more and more things have to be built to complete in order to be able to do a thing well.

But for consumers, such a high cost is not necessarily willing to afford, for example, they can easily get mutton pork, they don't want to spend more money, Fan Jingjing must keep these canned food at a certain price, so that ordinary farmers can make money.

Fortunately, the meat transported to Chang'an City is not cheap.

Fan Jingjing only needs to pay the cost price of the origin, but Fan Jingjing wants the originators to live a better life.

Fan Jingjing decided that what could be transported from a distance must be the pulp that was rare or even unavailable to Chang'an.

She also had to move some of the population to the south.

Create a second big city of a million people.
