Master of Thermodynamics

The reason why Renault had a whim and planned to "invent" ice cream was related to the batch of gifts he just received.

Evans, Hyde, Bentley and others didn’t know where to find out that Renault was a gourmet master and liked to make food by himself, so before Renault left, they tried their best to collect a lot of precious ingredients and packed them up 2 A large wooden box.

Among them is a can of brown sugar weighing 10 kilograms.

Although this brown sugar is not good in appearance, has more impurities and not enough sweetness, it is definitely a very sincere gift.

Because this can of brown sugar alone is worth more than 15 Kinnars.

In the alien world, there are currently no plants that can squeeze sugar on a large scale, such as sugar cane and sugar beets. It is quite difficult to obtain sugar. This kind of brown sugar comes from a shrub called the "black honey tree".

To be precise, it comes from its fruit seeds.

Please note that it is a "seed", not a fruit.

To squeeze brown sugar, you must first pick the black honey fruit from the black honey tree, peel off the seeds, and then boil the syrup to obtain the brown sugar.

The black honey tree grows in a harsh environment, there are not many fruits, and there are fewer fruit seeds, so the yield of brown sugar is extremely low.

Things are rare and expensive, and the price of brown sugar is so high that even the average little nobleman can't afford it.

At the first sight of brown sugar, Renault's obsessive-compulsive disorder broke out instantly, and he immediately had the idea of ​​refining white sugar.

What kind of words look like good candy, dark?

This is absolutely unbearable!

Must be refined.

With his ability, it is also very simple to do this.

Melt the brown sugar into sugar water, filter it repeatedly to remove impurities, add clarifying agents, namely lime, carbon dioxide, activated carbon, to remove the pigment, when the color of the sugar water is close to transparent, evaporate the water, and the white sugar is as white as snow. Yes.

This white granulated sugar is not only more pure, but also more sweet, which is very suitable for making desserts.

After thinking about it for a while, Renault decided to "invent" ice cream first because it was made in the simplest way.

White sugar, eggs, and milk are the raw materials of ice cream. As for the specific steps, Renault is a piece of cake.

Add white sugar to the egg yolk, stir it into a batter, pour in the milk, heat it to a certain temperature, continue stirring, after turning into a thick emulsion, freeze and cool down. In this process, you must continue to stir. At this step, the ice cream is formed. .

The trick to making ice cream is "stirring".

Looking back at the production process, you will find that it is almost a mess from start to finish, with almost no stopping time.

Why must it be stirred?

Because when stirring, the air will be uniformly mixed with protein, fat and water to become a creamy semi-solid mixture, which is described in professional terms, which is called "puffing".

It can also be understood that there are very few "dry goods" of ice cream, and it contains only "air" and "water", which is far more than puffed foods like potato chips.

Is there no water added to the puffed food?

But it is precisely because of its "less dry goods" that the taste of ice cream has become so soft and delicate.

Because protein, fat and water form countless extremely fine "cages", a large number of "air molecules" are trapped in the cages, forming a loose and empty structure.

When tasting ice cream, every time the tongue is licked up, the cage bursts, the trapped air molecules are released, and the tongue is gently massaged, so it has a "delicate" taste.

In fact, it is very troublesome and laborious to make ice cream by hand. If Nima keeps stirring, even the unicorn arm will feel tired.

In front of 【Nian Motive】, this is not a problem.

Under the control of Renault, the stirring speed is absolutely constant, which makes the mixing of the emulsion and air more uniform, and also makes the ice cream "produced" by Renault have a better taste.

When the three girls stepped into the cabin, they saw the ice cream that had just completed the puffing process, and Renault hadn't cooled it yet.

Under the novel and expectant gaze of the girls, Renault used his mind to move a new empty container and put it next to the glass jar.

Then he flicked his fingers, and dozens of ice cream **** the size of a baby's fist floated out of the glass jar, flew toward the empty container, and hovered inside.

The three girls looked surprised and confused.

Surprisingly, the appearance of ice cream **** is so cool. They suddenly emerged from a pile of white lotion, and after rolling in the air for a few times, they turned into perfect spherical shapes. This is simply a magic trick. .

What is stupid is, why did Lord Lord "put" ice cream **** into the empty container?

There seems to be a strange change on the surface of the ice cream ball, and the color has obviously changed slightly. Is this some kind of mysterious ritual?

What kind of food is the ice cream that Lord Lord wants to make? Even use rituals?

Although quite puzzled, no one dared to ask, but a sense of awe surged in their hearts.

In fact, there is nothing wrong with their thinking. What Renault is doing now can barely be regarded as a ritual.

But it's not mysterious at all, it's just cooling. What's the mysterious?

This is another stunt of Renault's ice cream making-low temperature quick freezing.

On the earth, some high-end restaurants will use liquid nitrogen to make ice cream to achieve the purpose of rapid cooling.

Why use liquid nitrogen?

To show off your skills?

Or use more expensive liquid nitrogen as a selling point?

of course not.

The chef is not so boring. The purpose of using liquid nitrogen is to improve the taste.

When frozen, the liquid water in the ice cream will form ice crystals, and the smaller the ice crystals, the better the taste of the ice cream.

This is easy to understand. If the ice crystals are very large, the water in the ice cream will become ice slag. Would you like to eat it?

Of course not.

I bite it so badly, my mouth hurts, whoever likes to eat, anyway, labor and management are unwilling to eat.

However, in the case of low-temperature quick freezing, more than 80% of the free water will quickly condense into ice crystals, and there is no time to combine into large pieces of crushed ice, and the lower the temperature, the smaller the ice crystals and the better the taste.

The temperature of liquid nitrogen is close to minus 200 degrees. When ice cream is soaked in liquid nitrogen, the ice crystal particles formed are very small, which greatly improves the taste.

With the ability to [reverse heat conduction], Renault can easily create super low temperatures, not to mention minus 200 degrees, minus 250 degrees is not a problem, so the exquisite taste of his ice cream is beyond the horizon.

It’s a pity that only those who are familiar with how to make ice cream can deeply understand the awesomeness of the god-level chef. The three girls don’t know what ice cream is, and they have no idea about it. Renault’s performance can be described as a bright pearl. cast.

After freezing for more than 30 seconds, Renault waved his hand. A dozen ice cream **** were divided into 4 piles and dropped into 4 delicate silver bowls. After repeating the operation twice, each silver bowl was filled with ice cream balls.

Then he smiled and said:

"You can try the ice cream first..."

Before the voice was over, the silver bowl floated to each girl's eyes automatically, and there was a silver fork floating beside the silver bowl, followed by a stronger sweet scent, which made people drool crazily.

The three girls stupidly took the silver bowl, and couldn't wait to fork a snow-white ice cream ball, put it in the mouth, and took a bite.

Then, a performance called "face changing" appeared on every girl's pink face.

When the three lips touched the ice cream ball, they couldn't help but shiver and frowned slightly.

So cold!

Is this the ritual performed by Lord Lord when making ice cream?

The moment their tongue touched the ice cream ball, their pretty faces showed huge surprise.

God, what kind of food is this?

It is incredibly soft.

It is more delicate than you can imagine.

This is a taste they have never felt before.

When the ice cream rolled in the mouth and touched the sweetness-sensing cells on the base of the tongue, the surprise on their tender faces instantly turned into a deep happiness.

The rich sweetness mixed with strong milk flavor is a taste they have never experienced before, and it also completely activates their nerve center, prompting their brains to secrete a large amount of dopamine, which makes them feel a kind of heartfelt happiness.

Describe it in one sentence.

This is the taste of happiness.

The girls think that the ice cream is unparalleled, but Renault feels quite satisfied.

He prefers yogurt ice cream. He also feels that ice cream without fruit is not perfect.

Therefore, compared with the food in front of him, he pays more attention to the beauty in front of him.

Watching three exquisite beauties sipping ice cream, the show's face was full of the ultimate enjoyment look. Against the white background, the three red pink lips added an indescribable temptation to make Renault kiss. The strong urge to go up.

He sighed contentedly in his heart.

Well, this is an afternoon worth looking forward to.

The coming night is even more exciting...
