Xiang Yan did not respond.

Just look down at the various ingredients.

The home version of ice cream is still very easy to make.

The main thing is to mix whipping cream with raw sugar egg yolk, then quickly whip it, and then put it in the refrigerator to freeze for half an hour.

It's just that the Great Zhou Dynasty didn't have a refrigerator, and there was no whipping cream.

This is also why Xiang Yan used the cool water produced by two barrels of deep wells to replace the refrigeration effect produced by the refrigerator.

Although its endurance is not on the same order of magnitude as the refrigerator of the refrigerator, it ...... As a replacement for short-term use, it is still not a big problem.

And for solving the problem of whipping cream, there are no shortcuts and alternatives.

It can only use its hands to achieve its dreams.

"Take a big bowl."

"I want another pair of iron chopsticks."

"What? There is no iron, only bamboo? ”

"It's okay, let's make do with it."

Xiang Yan held a large bamboo bowl in her hand, and first poured all the butter and sesame oil into the bowl.

Followed by.

Turn around and take out five full handfuls of frosting from the bag.

Toss in a bowl.

The frosting is crystal clear, which is very different from ordinary white sugar.

To put it simply, frosting is a sugar water that is close to vaporization, which is considered an aqueous compound.

Xiang Yan rolled up her sleeves and waved her thick arms.

One lap!

Two laps!

Three laps!

The number of laps is increasing, and the speed is getting faster and faster.

Sesame oil and butter, due to the difference in density, coupled with the speed of external force close to centrifugation, began to undergo a qualitative change!

Originally, they were two types of liquid and shapeless oil.

Now.

It's starting to solidify!

"Oh my God! Beat the oil like a beaten egg? ”

"That's amazing, what's going to be done?"

"Xiang Yan shouldn't be making cold sweet soup, this technique is very similar."

The students of the entire Guozijian were all around Xiang Yan, and they were talking about it.

"Sweet soup is so simple, have you ever heard of ice cream?"

Xiang Yan said.

Everyone was shocked and looked at each other.

"Ice cream? What is ice cream? Made of snow? ”

"Shhh...... I know about rice cakes and jujube cakes, but I've never heard of this ice cream. ”

"My father used to fight in the north, where ice and snow were rampant for many years, and it is said that some herders mixed sugar and oil and froze them into ice cubes to ensure nutrition on the battlefield."

"According to what you say, how greasy is the mixture of oil and sugar, can you eat it?"

Xiang Yan continued to speed up, and the oily mixture in the basin turned out to be a silky foam!

Then, Xiang Yan raised his hand and added frosting to the basin twice.

Keep stirring up the fast!

The foam becomes denser and thicker.

A moment later.

The dense foam already has the ability to set shapes.

This whipping cream.

It's finally done!

Xiang Yan breathed a long sigh of relief, fortunately he had a brute force to use, otherwise...... The arm strength of ordinary people is really not as good as that of an electric whisk.

Set this pot of whipping cream aside.

"Another pot."

Xiang Yan took another large bamboo basin from the man's hand, separated the egg white from the egg yolk, and left the egg yolk in the basin.

Followed by.

Add the sugar to a bowl and stir.

Xiang Yan shook his hand, loosened his muscles, and continued to dry.

This is the ingredient in making ice cream.

Beat the egg yolk and sugar mixture until smooth.

Again, add the sugar in 3 portions and beat it into a paste.

Then, put the whipping cream in two halves into the yolk bowl.

Continue to break up.

Xiang Yan held the basin with one hand, stirring wildly with the other, and the green tendons on his arms were visible to the naked eye.

The female Confucian students in the Guozi Prison couldn't help but feel a little dizzy on their faces when they saw this thick arm.

Boom!

Ultimately!

A large pot of glutinous hair products appeared in front of everyone!

As ice cream.

It's certainly enough on the inside.

However, at the moment, this appearance is really unsatisfactory.

"Xiang Yan, can you eat this thing?"

"That's right...... You're pretty fast, but you don't want to be edible. ”

"Is this what you mean by ice cream? The color is not like it, and there is no snow, so why is it called that? ”

Xiang Yan ignored it.

Just clasped the two basins together.

Then put the two basins into a bucket of cool water from a well that was just brought back.

In addition, find a larger bucket, put the bucket in the center, and take some clothes and cotton wool to pile in the gap between the bucket and the bucket to ensure a low temperature environment and last longer.

Then there was a long wait.

"Done?"

"This thing is soaked in water, can I still eat it?"

"Xiang Yan, is this what you do to better relieve the heat?"

"Could it be some kind of witchcraft?"

Seeing Xiang Yan clean up the production site, return to his seat and Erlang's legs, everyone asked.

"Don't be irritated, students."

"There's still more than an hour left for the evening class."

"You wait another half an hour, and it'll be fresh."

"Take this opportunity, I will also tell you, this is not witchcraft, this is ice cream, in my opinion, it is a kind of ice cream, it is a kind of melt-in-mouth, smooth in the throat, sweet silky, cold drink, after eating, the heart is cold, the heart is flying!"

Listening to what Xiang Yan said, everyone became more interested in the contents of the two wooden barrels.

......

Afternoon heat surges.

Inside the National Prison.

Dozens of students hot with dry lips.

Boys can catch the wind with their chests bare, but girls can only endure sweating.

"Xiang Yan, is that thing good or not?"

"That's right, we didn't go home between classes, so we're waiting for your ice cream here!"

"Hurry up, it's been more than half an hour, are you afraid of revealing your stuff and don't dare to let us see it?"

Xiang Yan yawned from the ground and pinched his fingers to calculate, it was time to come.

It's really hot this afternoon, and when I get some sleep, I get sweaty in my pants pockets!

"Don't worry, please keep your eyes on it!"

Xiang Yan took out the small wooden barrel, and two iron basins floated in it.

Lifting the lid of the iron basin, the flocculent hair under it seems to be frozen solid at the moment.

Seeing this scene, Xiang Yan couldn't help but smile with satisfaction.

That's the case.

A few days ago, I was hungry for the food on these blue stars, and I tasted it this time, and the taste is not right!

I opened a cloth bag, and it was densely packed with wooden spoons.

"Each girl has a spoon."

"Two boys share one."

"I'll taste it for you first!"

Xiang Yan directly dug up a big spoonful of ice cream, which melted in the mouth, and it was cold!

Hungry!

That's the smell!

Everyone saw Xiang Yan enjoying it so much.

I saw a burst of cold air coming out of the "ice cream" in the basin.

I've never seen such food, but ...... They all saw the process with their own eyes.

Not to mention.

Even Xiang Yan himself ate it.

The problem should not be too big.

Just as everyone was hesitating, Princess Yuanhua snatched the spoon from Xiang Yan, which he had just used.

Scooped a big spoonful of ice cream directly into the basin!

Put it in your mouth immediately.

Cool, smooth, moist, fragrant and sweet!

At least eighteen wonderful flavors converge on the taste buds to explode!

"Uh-huh!"

After Princess Yuanhua showed an expression of enjoyment, she immediately covered her head in pain.

Xiang Yan gloated and smiled:

"Don't eat too much at one time, otherwise you will have a headache, eat less at a time, and eat multiple times."

"Princess Yuanhua, the food I made to relieve the heat is no worse than your cold drink in the Western Regions, right?"
