That day.

Iron ore blasting.

Dozens of miners succeeded in opening the saltpeter mine.

To know.

Saltpeter is a mineral that is extremely difficult to mine in ancient times, and it is quite difficult to make and use.

Even if it is directly used in the production of gunpowder, the comprehensive input required for each catty of gunpowder is not less than 3 or 5 taels of silver.

Not to mention, saltpeter is used as a raw material for ice making.

If you make a pound of ice.

The comprehensive cost is at least two or three times that of gunpowder!

Xiang Yan estimated!

Now in his hands, he has a total of 10,000 taels of silver to use.

The cook can borrow from the third aunt, and the ice-making technique can be taught to them by a few family members.

The next thing I have to do is to purchase the raw materials for ice cream.

and the materials used to make ice.

"Steward Xiang, choose a few housekeepers in a while, and greet me at the door of the Yuxiang Restaurant that my third aunt gave me."

"Bring me the carriage from the house."

"That's right! Send someone to tell my third aunt and lend me two cooks! ”

Let's talk about it.

Xiang Yan turned over and hit the carriage directly.

Whip wielding.

Straight to the market.

Buy it a few thousand eggs first!

Buy a few hundred pounds of butter and sesame oil!

The weight of the carriage gradually increased.

The last is to buy sugar, 300 catties of frosting, 500 catties of white sugar.

There are these materials.

You can make at least 1,000 catties of ice cream.

The emperor wants 800 catties, and the rest will be taken to the market first, sold, see how the market is, and then make the next decision.

Sigh!

The horse neighsed!

The carriage stopped in front of the restaurant.

The family members rushed up and moved all the items on the carriage to the back kitchen.

"Is the cook here?"

Xiang Yan asked.

Jia Ding nodded and said:

"I'm waiting for you in the back kitchen!"

Xiang Yan strode inward.

The two chefs, both bald, with fierce faces and strong bodies like oxen, thought they were members of the underworld if they didn't know.

"Hello boss!"

"We are the special kitchen of Yuxiang Restaurant, and one is guaranteed to be used by 10 people!"

"Please do your bidding!"

The enthusiasm of the two chefs was beyond Xiang Yan's expectations.

Xiang Yan pointed to the materials on the ground.

"I'm going to teach you how to make a dish called ice cream."

"But I'll only teach it once, and if I can't learn it, you'll leave."

"Do you understand?"

The two chefs are confident:

"Guaranteed Society!"

Xiang Yan didn't say a word, and directly started making ice cream.

A set of actions is smooth, especially the speed of stirring, which is even more amazing!

The two cooks watched Xiang Yan's every movement intently, until he put the bamboo basin into the well to pull out the cool water.

That's it!

"Put it in cold water for half an hour, and then you can take it out and eat it."

"But the effect of the cold water is short-lived, and in a moment, I'll bring you ice."

"You two do it again, I'll see how it goes?"

Xiang Yan said.

The two chefs burst their clothes and dried them directly.

Although I have only met once, the learning ability of these two chefs is really not covered.

The processing and application of some materials even far exceed Xiang Yan!

Seeing this scene, Xiang Yan was relieved.

"Yay!"

"You're doing it right here!"

"Can you make a thousand catties today?"

The two chefs responded confidently:

"No problem!"

After the big joy.

Xiang Yan turned around and said to the others:

"Leave two people to clean the cellar of the restaurant, and the rest will follow me to the saltpeter mine outside the city!"

"Yes!"

Saltpeter mines, mining sites.

The miners use their most skillful methods to meticulously mine the saltpeter mines.

The value of saltpeter is far more than iron ore several times, and out of reverence for nature, they don't want to waste every penny, every penny!

Soon, a large bucket of saltpeter, about 20 catties, was mentioned in front of Xiang Yan.

Xiang Yan placed a little coarse salt in the center of the saltpeter and melted it with clean water.

Then a small part of saltpeter inkstone is turned into a powder and added to the brine.

Take out two wooden basins, one large and one small.

In a small wooden basin, put the liquid you just prepared.

In the large wooden basin, add saltpeter, and then on top of these two basins, put a larger wooden basin hollowed out in the middle, and cover the whole place.

Pour the water straight onto the saltpeter.

It turned into ice in an instant!

The ice spread rapidly over the hollowed-out tub in the middle.

In less than half a minute.

Half a basin of ice has already gathered!

The heat wave outside the tent gushes, and the cold air in the basin is rising!

Seeing this scene, everyone was shocked.

"Starting today."

"Ice is made here, and then it is sent directly to Yuxiang Restaurant."

"You will make ice according to my method, a thousand catties a day."

"Strive to fill the cellar of Yuxiang Restaurant within three days!"

"Since people don't sell us, then we will make the fifth largest ice cellar in the capital by ourselves!"

Xiang Yan's speech was impassioned, and this group of cronies who had been with him for a long time were even more convinced!

Then, Xiang Yanchang spurred his horse and returned to Yuxiang Tower.

The big ice cream plan is officially running!

For now, just lie in this attic and wait quietly for a few hours, and everything will be settled.

Xiang Yan sat firmly in the rocking chair, waving a paper fan in her hand.

It's not pleasant.

And all of this was seen by Guo Lin, who was secretly tracking.

"You can't make ice cream without an ice cellar!"

"The emperor blames it, your marriage contract with Princess Yuanhua will definitely be blocked!"

"Xiang Hanzi, don't blame me for being ruthless!"

......

Two hours later.

In the afternoon, the heat wave gushed out, waking up the sleeping Xiang Yan.

Xiang Yan went downstairs sleepily, thinking about eating some ice cream to relieve the heat.

But there was no cook, only huge wooden basins stacked together in the back kitchen.

"Oops!"

"Shopkeeper, are you awake?"

Xiang Yan was a little confused, wondering, are these two lazy?

"What are you doing?"

"Finished with ice cream?"

The two chefs smiled calmly:

"Childe!"

"We made 1,500 catties, but there are no materials, we just went to buy the materials according to the rules you used in teaching."

When I got closer, the two chefs were covered with eggs, sugar, and oil cubes......

"Today's ice-making task of 1,000 catties!"

"Done!"

Rubbing their sour arms, the two chefs were full of pride!
