Chương 7: What the Data Paid Back

For the next three days, Chris's life was stripped to the bone. Sleep, slice potatoes, roast potatoes, analyze data, then eat the "failures" from practice. His apartment hung with the mingled smell of potato and butter. The living-room table, the couch — everywhere — were stacked with the notebooks and scratch paper where he logged his data. He slept four hours a night. The first thing he did on waking was walk to the kitchen and pick up his knife. Thock, thock, thock.

The sound of slicing became the only background music in the place. He no longer needed to consciously trigger Data Eye to check each slice. After hundreds, thousands of repetitions, his hand had built its own muscle memory. He could even tell from the feel of the blade crossing the potato whether the cut was running thick or thin. [This batch (31 slices) — average thickness: 2. 01 mm, standard deviation: 0. 04 mm] Looking at the latest reading, Chris let out a long breath. Standard deviation 0. 04 mm.

It meant the thickness variation across all his slices was now small enough to ignore. That laid the firmest possible foundation for a uniform cooking time downstream. [Knife Work: B- (69/100) → B (70/100)] At last, his Knife Work broke through the B- ceiling and entered B. Only sixty-nine to seventy, a single notch — but Chris knew what it meant. It meant his fundamentals had reached the qualified level of a professional chef. He set the knife down and rubbed his aching wrist.

In three days he'd cut at least fifty pounds of potatoes. Fresh blisters had risen on his knuckles, and old ones had hardened into calluses. This pure, body-driven repetition was dull, tedious, even painful. But every time he saw that slowly climbing number on the panel, all of it was worth it. The system wouldn't hand him ability for free — but it would never let his effort go unanswered. The first goal of the knife module: achieved. Next came the real hard fight. Heat.

He walked to the cheap oven, his expression complicated. This oven was the source of his failure, and the fortress he now had to conquer. From the theory in the Heat-Perception Manual, he knew the biggest problem with a home oven was unstable temperature and uneven heat. Set to 400°F, the true interior might swing violently between 380 and 420. What he had to do was learn this machine's temperament inside out. He spread yesterday's slices evenly on a tray, dividing it into nine zones, like a tic-tac-toe grid.

Then he slid the tray in. He didn't trust the dial markings outright. He started his phone's stopwatch and brought every one of his senses to bear. The narrative has been stolen; if detected on Amazon, report the infringement. He listened to the hum of the heating element — its strength signaling whether it was running at full power. He watched the little glass window in the door, tracking where on the slice edges the color first began to turn.

Every five minutes he opened the oven, took a probe thermometer, and quickly measured the center temperature of all nine zones, logging each.

"Minute 5: top-left 185°F, center 200°F, bottom-right 180°F…"

"Minute 10: top-left 290°F, center 315°F, bottom-right 285°F…" It was an extraordinarily tedious process, like running a stress test on an underpowered server. The first batch came out a disaster. The nine zones held nine different states. The center slices were charred black; the corners still raw at the core.

"Figures." This oven's element sat in the center, driving the middle far hotter than the edges. Chris didn't lose heart. He logged the data, threw out the failed batch, and loaded a fresh one. This time, halfway through, he quickly pulled the tray, rotated it 180 degrees, and slid it back in. The result was a little better. The gap between edge and center had narrowed, but the whole thing was still slightly overdone.

"Too long." He kept logging and started the third experiment. Shorter time, higher starting temperature, a mid-cook drop… Like a mad scientist in the tiny laboratory of his kitchen, he tuned variables and watched results without pause. Fail. Fail. Fail again. His trash can filled with potatoes burnt or undercooked. The smell of scorch in the apartment grew heavier, until he had to open every window to air it out. Once, too exhausted, he fell asleep leaning against the wall while waiting on the oven.

When the thick smoke choked him awake, the whole tray had gone to black charcoal — and tripped the smoke alarm, its shriek tearing through the apartment, drawing a neighbor's knock of protest. Apologizing while frantically dealing with the mess, in that moment, he truly felt utterly wretched and beaten. He asked himself whether any of this meant anything. Working himself into a madman for a slim, intangible shot at a revival round. Maybe Dave was right.

He should go back to being a programmer, at least live like a normal person. And just as his will wavered, his phone rang. An unknown number. He hesitated, then answered.

"Is this Mr. Chris White?" A formulaic woman's voice.

"Speaking."

"Hello, this is the production team for Burning Kitchen. We're notifying you that we'll be holding a revival challenge next week, and you've qualified to compete. The time and location will be sent to your email — please watch for it." A roar went off in Chris's head. Here it was. It was really here.

"… Got it. Thank you." He fought to keep his voice level. He hung up and stood there, frozen, for a good half a minute. Then an enormous, wild joy drowned him. Every bit of his persistence, all his grinding work — in this instant, all of it had meaning. He rushed to the oven and looked at the batch roasting inside, his eyes turning rock-steady. He had no time left to wallow, no time to doubt himself. He had one week. Inside that week, he had to break through the wall of heat control.

He picked up his pen and drew a curve in his notebook. Horizontal axis: time. Vertical axis: temperature.

"High heat at the start, lock the surface moisture fast… then drop the temperature, let the heat seep slowly into the core… then back up at the end to form a crisp shell…" What he was designing wasn't merely the cooking steps for a dish. It was a one-of-a-kind victory curve, tailored to this cheap oven. He fed in all the data from dozens of earlier failures and corrected for it. Then he loaded a fresh tray of slices and manually worked the oven's switch and temperature in strict obedience to his curve.

Forty minutes later, he opened the oven. A rich aroma of butter and potato rolled out at him. Every slice on the tray showed an even gold, edges curling faintly, touched with a beautiful trace of brown. He pressed a slice with the knife tip. Perfect resistance. He put it in his mouth. The shell was crisp, a faint crack, and the inside ran smooth and fine as cream. Ding. [Through repeated experiment and data analysis, you have begun to master heat control on non-standard equipment.] [Heat Control: C (58/100) → C+ (62/100)] Up four points. Chris's fist tightened. This wasn't just a four-point stat bump. It was a single step he'd carved out for himself with his own hands, out of the bottom of the abyss, paid for in sweat and failure. He looked out at the Los Angeles night, and felt the whole world had changed. In a week, he'd return to the kitchen that had shamed him. But this time, he was no longer a lamb laid out for the slaughter.
