Yukinoshita's Correction Method

"Just tell me whether you did it or not." Dong Yunshan ate biscuits and drank black tea. "Pre-made dishes are still dishes, and pre-made biscuits are of course still biscuits."

"But..." Yuigahama Yui wanted to refute, but couldn't find a suitable reason. She could only look at Yukinoshita Yukino for help, "Xiao Yukino..."

Yukinoshita Yukino pinched the biscuit in her hand and said, "This method is very good."

Yuigahama Yui: “Huh?”

"Let's try again." Yukinoshita Yukino repeated the previous process. "You've already mastered slicing and baking. Now I'll give you the penultimate step."

Yuigahama Yui follows the method of making Yukinoshita Yukino, sifting in low-gluten flour twice, cutting and mixing with a spatula, and kneading it into a loose dough.

Put it in the refrigerator to freeze for a while, press it into cookies and put it in the oven.

"It seems..." Yuigahama Yui suddenly realized, "I feel a little involved."

"Next is the third to last step." Yukinoshita Yukino panted slightly and wanted to continue.

"Let me do it." Dong Yunshan reached out to take the round bowl.

Yukinoshita Yukino held the bowl tightly.

Dong Yunshan added: "I want to practice more."

Only then did Yukinoshita Yukino let go of her hand.

Azuma mixed the butter, sugar and salt together, beat until pale and fluffy, and then gave it to Yuigahama Yui.

Yuigahama Yui added egg liquid twice, added vanilla extract, and then repeated the process.

Success again.

In the end, all the steps were left to Yuigahama Yui to complete on her own.

Yukinoshita Yukino's only task is to stop Yuigahama Yui from adding peaches into it.

Eating the cookies that she made entirely by herself, and savoring the taste that was almost the same as those made by Yukinoshita Yukino, Yuigahama Yui just blinked her eyes lightly, and crystal tears rolled down her cheeks.

"I...I really did it..." Yuigahama Yui sniffed, "Actually, I just said I would try a few more times because I was worried that Yukino would be angry. I didn't expect it to be so...delicious..."

Yukinoshita Yukino was slightly startled, then sighed helplessly, "We've already made a good start. If you want to play freely in the future... at least don't change too much at once."

"I feel like we'll have lots of cookies to eat in the coming days." Hikigaya Komachi laughed happily, "Yeah!"

This was indeed the case, and Yuigahama Yui happily baked cookies for several days.

And then sure enough...

Azuma Yunshan and Yukinoshita Yukino looked at the unknown substance in the beautifully packaged bag with heavy hearts.

"I didn't expect it to turn out like this..." Yuigahama Yui inexplicably felt guilty handing over a poorly-done test paper to her parents for signature.

"Even though it doesn't look... well, it doesn't look very good," Hikigaya Komachi encouraged the two, "it actually tastes pretty good."

Yukinoshita Yukino stared at the thing in her hand and looked up at Azuma Yunshan.

Dong Yunshan took out a biscuit...just treat it as a biscuit, and threw it into his mouth: "It's really good, with a fresh aroma of vegetables."

Yukinoshita Yukino then ate a piece and said, "Indeed."

"If the taste is okay, then I'll have to work on the appearance!" Yuigahama Yui said enthusiastically, "Cooking is really fun. What should I try next...ah, how about cake?"

"A great choice." Yukinoshita Yukino nodded. "They all require an oven, so learning should be easy."

"But I saw someone baking a cake the other day, and it seemed difficult." Yuigahama Yui was a little worried, "The girl tried many times, but the cake she baked was always soft and fluffy."

"Maybe the temperature isn't high enough," Yukinoshita Yukino analyzed. "Cakes rely on high temperatures to quickly vaporize the water in the batter, quickly release the gas from the baking powder, and steadily expand the egg white foam. If the temperature isn't high enough, the batter won't set in time, and the bubbles inside will merge or burst, causing it to collapse after it comes out of the oven."

"So all we need to do is turn up the temperature a bit?" Yuigahama Yui's face showed a hint of confusion, "But her friend uses the same temperature."

"Insufficient temperature is just one of the reasons. There are many other possible reasons." Yukinoshita Yukino gave examples, "Mixing problems, material problems, proportion problems, etc."

"So..." Yuigahama Yui's face became even more confused. "Will it be possible that the same batter is baked in the same oven at the same temperature for the same time, but the results are completely different?"

Volume 5 May Holiday: Chapter 157 Oven Puzzle

"If that's the case, then there's no need for the recipe to exist." Yukinoshita Yukino felt a little strange. "Why do you think this would happen?"

"The girl I saw in the home economics classroom was the one I just talked about." Yuigahama Yui recalled the scene at that time, "While I was baking cookies there, she was baking a cake. She baked it twice but it was still soft. I thought it was a problem with the oven, and then her friend came and helped her bake it."

"Maybe a friend came over, noticed the temperature wasn't right, and turned it up," Hikigaya Komachi speculated. "And you didn't notice?"

"I really didn't notice it at first," Yuigahama Yui shook her head. "But after that classmate's friend left, she tried it again and muttered, 'It's not set wrong, it's this temperature.'"

"If one person can bake a successful cake and another fails at the same temperature and in the same oven, then the problem must be with the batter." Yukinoshita Yukino put down her teacup and flipped through the pages of her book. "After all, not even the same batter made by the same person is exactly the same. Excluding the possibility of the baking powder becoming ineffective due to moisture, the batter being too thin, over-mixing, or under-beating the egg whites can all cause the cake to collapse."

Yuigahama Yui's enthusiasm waned a bit: "Cakes are indeed much more complicated than cookies..."

"That's not quite right." Dong Yunshan, holding a biscuit in his mouth, seemed to be lost in thought. "Why do you say 'It's not adjusted correctly, it's this temperature'...?"

"That's right." Hikigaya Komachi grasped the key point. "If you want to grill at the same temperature, you don't need to adjust the temperature control knob."

"So..." Yukinoshita Yukino frowned slightly, "After her friend helped her bake the cake, she adjusted the temperature control knob?"

"But why do you do that?" Yuigahama Yui was puzzled. "When Yukino taught me before, she didn't specifically let me adjust the temperature myself."

"I should have done that. It would have made a deeper impression on you." Yukinoshita Yukino realized her mistake. "I was negligent. You should develop the good habit of checking the temperature."

Yuigahama Yui: “…”

"So, by turning the temperature knob, my friend wanted that student to learn how to control the temperature on his own?" Hikigaya Komachi thought, and it seemed to be a bit off. "But...that student didn't succeed either."

"What if that friend," Dong Yunshan put his fingers together and tapped his temple, "just doesn't want that classmate to succeed?"

"They seemed to have a good relationship..." Yuigahama Yui recalled the scene at that time, "There's no need to do this."

"No." Yukinoshita Yukino's eyes were cold. "It's only possible because we have such a good relationship."

Dong Yunshan and she exchanged a glance: "Divide into classes."

Yukinoshita Yukino nodded: "Reorganization of interpersonal relationships."

Yuigahama Yui was confused: "What are you talking about?"

Hikigaya Komachi looked left and right: "I understand."

It's very simple, flirting has been turned into riddles.

Yuigahama Yui: “Huh?”

"It's irresponsible to make groundless speculations." Yukinoshita Yukino carefully put the bookmark in place, closed the book, and put it away. "Let's go to the home economics classroom to check now."

"If that friend is careful enough," Dong Yunshan also stood up, "maybe we can meet him."

The Servant Club went out as a group, including Yukinoshita Yukino who wanted to confirm the truth, Azuma Yunshan who wanted to have fun, and Yuigahama Yui who was confused.

and Hikigaya Komachi of the Film Research Society.

She's been more interested in researching the Service Club than movies lately.

You can study movies anytime, but the Servant Club broadcasts them live every day.

"I remember it was..." Walking into the home economics classroom, Yuigahama Yui recalled and searched, finally pointing to a corner, "It's that oven."

A few people walked closer to observe and found that the oven was not much different from other ovens.

"If that's the case, the problem is with the temperature control knob." Yukinoshita Yukino turned the knob left and right. "Sure enough... find something like a spoon or a fork."

"No need." Dong Yunshan pinched the knob with two fingers and pulled it out with a little force. "Done."

Yukinoshita Yukino grabbed Azuma Yunshan's wrist, looked at his fingers, and found no signs of injury. She gave him a sidelong glance and then looked at the fixing hole behind the knob between his fingers.

"Polishing marks." Yukinoshita Yukino grabbed Azuma Yunshan's wrist and handed the temperature control knob to Hikigaya Komachi and Yuigahama Yui. "Can you see it?"

Yuigahama Yui didn't even have time to look at the knob.

Aren’t Yukinoshita Yukino’s movements a little too natural?

Dong Yunshan has long been accustomed to it.

When Yukinoshita Yukino was cooking, Azuma Yunshan felt that he was thick-skinned and was burned by the oil without feeling any pain. He just shook his hand and continued working.

Yukinoshita Yukino would pull his wrist and check it carefully.

"Can't you see clearly?" Noticing that their eyes were completely distracted, Yukinoshita Yukino let go of Azuma Yunshan's wrist and pointed at the D-shaped shaft of the oven thermostat. "This one's been polished too."

"Really?" Yuigahama Yui leaned in to observe, "What...what is this?"

"A mechanical thermostat's core component is a bimetallic strip formed by laminating two metals with different thermal expansion coefficients. When the temperature changes, the two metal layers expand at different rates, causing the bimetallic strip to bend. This triggers a mechanical switch that disconnects the circuit and stops heating," Yukinoshita explained. "Turning the knob rotates this D-shaped shaft, adjusting the trigger threshold of the bimetallic strip."

"Ah... um... I completely understand." Yuigahama Yui had an expression of complete confusion on her face.

Hikigaya Komachi curiously asked, "What effect will polishing the holes and shafts have?"

"Set the actual temperature to a different temperature than the one indicated on the knob." Dong Yunshan pushed the knob back in. "For example, set it to 180°C and turn it normally."

Dongyun Spruce turns the knob to the corresponding position.

"Because the hole and the shaft have been polished, a fan-shaped gap is formed. This allows the knob to rotate a certain angle without causing the shaft to rotate." Dong Yunshan applied slight pressure with his fingers and turned the knob. "This way, the displayed temperature is 165°C, while the actual set temperature is still 180°C."

"So... the classmate Yui mentioned and that classmate's friend, Classmate A and Friend B." Hikigaya Komachi changed to a more convenient name, "They seem to use the same temperature, but Friend B actually uses 180°C. So Friend B succeeds, but Classmate A always fails."

Volume 5 May Holiday: Chapter 158 Mutual Understanding

"Because Student A used the correct temperature, to achieve this effect, the oven temperature must be lower than the setting on the knob." Yukinoshita Yukino found the oven thermometer from the home economics teacher, put it in the oven, and turned the temperature control knob to the highest setting. "The mechanical thermostat may age due to long-term use, resulting in temperature deviations. So if you find that baking often fails, you need to correct it."

After the oven thermometer pointer stabilized, Yukinoshita Yukino concluded: "It's 10 degrees Celsius lower than the maximum temperature."

"Wait... let me do the math..." Yuigahama Yui's mind was a little confused, "Suppose the correct temperature for baking a cake successfully is 200℃. When classmate A turned the knob to 200℃, the actual temperature of the oven was 190℃, so the cake baked out was soft and fluffy."

Being able to get into Sobu High School, Yuigahama Yui should have no problem with this level of addition and subtraction.

"Then when friend B baked, he turned the knob to 210°C. The actual temperature of the oven after operation was 200°C, and he was able to successfully bake the cake." Yuigahama Yui raised her hand and made a twisting motion. "Then, using the gap between the shaft and the knob, without moving the shaft, he turned the knob back to 200°C. So, in the same oven, the temperature displayed by the knob was 200°C, but one cake was successfully baked, while the other was soft and mushy."

"To do this, Friend B needs to turn the oven a few more times, using habitual movements to cover up the fact that he's adjusting the temperature." Hikigaya Komachi stared blankly at the oven in front of her, which was still emitting heat. "Why do they do this?"

"After the class division, interpersonal relationships were restructured. My good friend who used to bake cakes together was assigned to a different class. With fewer opportunities to interact, she must be feeling lost." Dong Yunshan looked at the oven with a smile. "If I can tamper with the oven a little so that she can't bake a cake on her own, she'll come to me and our friendship can be maintained like this. Is that what you think..."

Dong Yunshan looked towards the door of the home economics classroom: "Friend B."

"My name is Risa."

Under everyone's gaze, a female classmate in uniform opened the door, her eyes swept over everyone, and finally stopped on Yuigahama Yui.

"I was a little worried when I noticed you were watching us yesterday." Risa looked at Yukinoshita Yukino and Azuma Yunshan again, "I just didn't expect that we would be discovered to this extent."

"I'm sorry..." Yuigahama Yui apologized subconsciously.

"You shouldn't say sorry." Yukinoshita Yukino's expression was cold, "She should thank you instead."

"I've heard of you, Yukinoshita Yukino. You're indeed the same person as the rumors said." Risa smiled sadly. "Someone like you who is good-looking and has a wealthy family, of course, can't understand the feelings of someone like me."

"This has nothing to do with Yukino-chan!" Yuigahama Yui stood in front of Yukinoshita Yukino, furious. "It was you who did something wrong, why do you say such things!"

Yukinoshita Yukino was slightly startled: "Yui..."

"Most of the world is made up of ordinary people like you and me, but not everyone thinks the same way as you." Hikigaya Komachi blinked. "You can't represent people like you—at least I don't want to be represented by you."

"I don't expect good friends like you, who can enthusiastically research anything they find wrong, to understand how difficult it is for me." Risa clenched her fists. "You have no idea how difficult it is to make a good friend!"

Yukinoshita Yukino moved her lips but said nothing.

"So you deliberately made your friend's cake-baking attempt fail?" Dong Yunshan reached out and pressed the oven. "Everything you did succeeded on the premise that your friend would continue to use this oven because of your friendship. It was a testament to your friendship. And you took advantage of that friendship and destroyed the evidence of it."

"Of course I know about that! I know everything..." Risa took a deep breath, "We used to bake cakes together, but after school started, she stopped joining me... When she can bake cakes by herself, or no longer uses this oven, it means... I just hope that day will come later. I can't stop her from changing the oven, I can only..."

If this were a movie, sad music would be playing now... Hikigaya Komachi took a step back and felt that the composition in her field of vision was even more perfect.

But then again, it was just baking a cake, how could it create the atmosphere of a murderer making a tragic confession before being taken away by the police?

"Perhaps, I should really thank you." Glancing at Yuigahama Yui, Risa approached the oven and took out tools from her schoolbag. "You made me realize how boring... and pathetic this kind of thing is. You can tell the teacher whatever you want, but please wait for me to fix it first."

Risa had obviously looked up relevant information and her movements were very skillful.

"Um..." Yuigahama Yui hesitated for a moment and spoke carefully, "Actually, I've been learning to make handmade cookies recently."

Risa raised her eyes: "So?"

"I couldn't bake it well by myself, so Yukino taught me step by step. But later, when I practiced on my own, I encountered many problems." Yuigahama Yui looked at Yukinoshita Yukino gently, "If I ask Yukino, I will know where the problem is right away. But... I still want to study it myself, because I want to reassure Yukino who helps me, and don't want her to worry about me..."

Risa paused: "You mean..."

"Your friend might have the same idea." Yuigahama Yui embarrassedly avoided her gaze, "She was worried that you would still be worried about her in your new class, so she wanted to make the cake by herself to reassure you."

"That kind of thing..." Risa bit her lower lip and sniffed while repairing the oven, "How would I know about that kind of thing..."
