Chapter 187 Braised Pork Rolls?
Jiang Yan had just sent a message in the group chat when his screen was flooded with "Hello, Professor" messages.
Physics students immediately chimed in, "Professor Jiang, quickly use your physics knowledge to analyze why the boss's roujiamo (Chinese hamburger) smells so good?"
He adjusted his glasses and began typing seriously: "From the perspective of molecular thermal motion, the temperature of a freshly baked roujiamo rises, the aroma molecules diffuse faster, and it is easier to stimulate the olfactory nerves; the crispness of the bun is related to the rate of moisture evaporation. High-temperature baking causes moisture to evaporate quickly, forming a structure that is crispy on the outside and soft on the inside, which conforms to the principle of optimal taste in mechanics."
The group chat instantly erupted in "Wow!"
A chemistry student chimed in: "Additionally! The flavor compounds produced by the Maillard reaction between the amino acids and sugars in the sauce are the soul of the dish!"
Watching this "academic discussion," Su Yingxue smiled and sent a red envelope: "Thank you for the professional analysis from the professor and classmates! The luckiest person will receive a 'Professor's Exclusive Set Meal'—a double-flavor roujiamo (Chinese hamburger) + braised egg + plum juice!"
The moment the red envelope was sent, the group went into "frenzy mode." Jiang Yan stared at the screen, his fingers clicking rapidly, and he actually managed to grab the best one!
He paused for a moment, then sent a message, somewhat embarrassed: "Luckily. I'll pick it up after class tomorrow. Thanks, boss."
The students immediately joked, "Did the professor use physics formulas to calculate exactly where the red envelope would land?"
"Please, professor, share your secrets to grabbing red envelopes!"
Jiang Yan didn't reply again, but quietly pinned the group chat to the top.
The next day after class, he indeed came to the stall with his briefcase. Su Yingxue smiled and handed him a set meal: "Professor Jiang, your exclusive perk!"
He took the set meal, bought a few more, and said, "I'll get some for my colleagues in the office too, so they can also try this 'mechanically optimized' roujiamo (Chinese hamburger)."
Seeing this, the students around him took out their phones to take pictures, and soon photos of "Professor Jiang checking in at a roujiamo (Chinese hamburger) stall" appeared in the group chat, with the caption "A perfect collision of academia and everyday life!"
Looking at the lively crowd, Su Yingxue felt a warmth in her heart—this little fan group not only connected her with the diners, but also added a unique touch of brilliance to the lively atmosphere of this alley.
After finishing his meal, Jiang Yan did not leave immediately, but stood by the stall and observed for half an hour.
He took out his notebook and started recording Su Yingxue's steps while frowning and thinking, "The three steps of making the flatbread, stuffing the meat, and drizzling the sauce can be optimized to reduce the waiting time."
That evening, he posted a "Scientific Operation Plan for Roujiamo (Chinese hamburger) Stalls" in his fan group, detailing three core optimization points:
1. Zoning Method: Divide the stall into "baked bun area", "braised area" and "assembly area". Pre-baked buns are kept warm, and braised meat is cooked in batches to avoid inefficiency caused by switching between multiple tasks at the same time;
2. Improved measuring tools: Use custom-made stainless steel spoons to scoop meat, with each spoonful weighing 20 grams, which ensures uniform portioning and reduces weighing time; use squeeze bottles to dispense sauce, following the standard "one squeeze, two turns" procedure to ensure consistent sauce amount in each serving of bread.
3. Queue management optimization: Set up "ordering area" and "collection area" in front of the stalls. Students first order in the ordering area (add spicy/add braised egg), scan the code to pay and get a number tag, and then wait for their number to be called in the collection area to avoid congestion.
Su Yingxue's eyes lit up as she looked at the detailed plan.
The next day, when she set up her stall, she adjusted the operating procedures according to Jiang Yan's design: the pre-baked flatbreads were placed in a warming box, the braised meat was cooked in two separate pots, and the assembly area was specifically for filling the meat and drizzling the sauce. Sure enough, the original 5-minute serving time was shortened to 2 minutes, and although the queue was still long, it moved much faster.
One student exclaimed in the group chat, "The queue was much faster today! Thanks to Professor Jiang's 'scientific blessing'!"
Upon seeing the message, Jiang Yan adjusted his glasses and replied in the group chat: "Practice is the sole criterion for testing truth. As long as it works, that's good."
After finishing with a wave of customers, Su Yingxue picked up her phone and sent a message to Jiang Yan: "Professor, your solution was so effective! I'll treat you to a special roujiamo (Chinese hamburger) tonight!"
I quickly received a reply: "Okay, let's also talk about how to optimize the temperature control of the insulated box."
Looking at the words on the screen, Su Yingxue smiled—it turns out that even in the mundane details of everyday life, there is a touch of scientific romance.
Thanks to the professor, the number of people joining the group and making purchases has increased today. Su Yingxue discovered that the system's task is almost complete.
Sure enough, less than half an hour later, a notification popped up on the system interface: "The number of fans in the fan group has reached 500. The task is complete! Reward: New product recipe - Secret Recipe Braised Meat Rolls!"
Su Yingxue's eyes lit up. She swiped her finger across the virtual recipe and looked at the description: "Braised eggs, dried tofu, and kelp knots with a special sweet and spicy sauce, rolled into freshly made pancakes." She couldn't help but smile.
She had just handed the last roujiamo (Chinese hamburger) to a student when she saw the group chat explode with activity. Some people were asking when she would set up her stall next, some were posting photos of the roujiamo they had just bought, and others were urging her to add new items.
Su Yingxue tapped her finger on the screen and sent a message: "Thank you everyone for your support! We'll be launching a new braised meat wrap tomorrow. The first 50 customers who come to the store will get a free plum juice with their wrap purchase!"
As soon as the message was sent, the group chat was flooded with replies like "Wait here" and "I'll definitely come tomorrow."
Su Yingxue put down her phone and looked at the bubbling secret sauce in the pot, feeling full of energy—the fan group was just the beginning, and she wanted to make the lively atmosphere of this alleyway spread further and stronger.
Before dawn, Su Yingxue arrived at the market, her feet glistening with morning dew, and picked out the freshest free-range eggs, chewy handmade tofu, and thick seaweed knots.
Once home, she first poured her secret-recipe braising liquid into a large pot—this was made by adding star anise, cinnamon, bay leaves, and a little rock sugar to the original roujiamo sauce. The braising liquid was thick and shiny, and a rich aroma wafted out as soon as it was turned on.
She gently cracked the eggs and put them into the braising pot along with the dried tofu and kelp knots, simmering them over low heat for an hour.
The braised eggs have absorbed all the broth, turning the egg whites a deep brown color, and when you peel them gently, you can see the runny yolks.
The dried tofu becomes soft and flavorful, bursting with juice when you bite into it; the kelp knots have a salty-sweet braised aroma, and are crisp and refreshing.
Next, she made thin pancakes. She used high-gluten flour, added warm water to knead the dough, let it rise, rolled it into pancakes slightly larger than her palm, and then slowly cooked them in a frying pan over low heat.
The pancakes are baked until golden brown on both sides, with the edges slightly curled up. They are crispy with a wheat aroma, yet still chewy, just right to hold the generous filling.
Finally, prepare the sweet and spicy sauce by mixing homemade chili sauce with honey, light soy sauce, and a little balsamic vinegar. Stir well to create a sweet and sour sauce with a hint of spiciness that balances the richness of the braised flavor.
Take a hot pancake, spread on slices of braised egg, chopped dried tofu and kelp knots, drizzle with a large spoonful of sweet and spicy sauce, sprinkle with a handful of bright green scallions and white sesame seeds, roll it up, wrap it in oil paper, and a steaming hot secret-recipe braised meat pancake is ready.
