| Ingredient | Amount |
|---|---|
| Pork femur (tonkotsu concentrate) | 600g |
| Whole chicken (paitan concentrate) | 1500g |
| Water (dual stock) | 2000ml |
| Ghost pepper rayu | 15ml |
| Fermented chili tare | 30ml |
| Extra-thick straight noodles | 140g |
| Spicy nikumiso (minced pork) | 50g |

Phase 1 — Dual stock prep (parallel): Tonkotsu concentrate 4h + tori paitan 3h, each reduced to 40% volume separately. Phase 2 — Fusion emulsion (45 min): Mix 60% tonkotsu / 40% chicken at 85°C; whisk until unified ivory-orange. Add ghost pepper rayu at minute 30 — capsaicin binds to fat (+14 aroma spike). Phase 3 — Heat hold: Maintain 92°C service temp; chili oil floats — stir once before ladle. Never hold >20 min post-rayu or capsaicin volatilizes (−20 aroma).
Barikata-firm 20s in extra-thick straight noodles — absorbs chili oil without going mushy. Double shake mandatory (chili oil adhesion 91%). 18s: undercooked center (−6). 20s: target. 25s: acceptable for mild-eaters. 30s: −10 umami + noodle breaks on lift. 45s: catastrophic sludge — auto −25 Raymond score.
Wide shallow bowl for heat dissipation control. Nikumiso mound dead center (gravity anchor). Habanero charred whole at 12 o'clock — visual heat signal. Green onion tower 6 cm height at 3 o'clock; egg half at 9 o'clock. Chili rayu drizzle 3 ml AFTER noodles, 2s before onion — oil cap locks capsaicin vapor (+8 aroma). Never pre-mix nikumiso into broth.
Cost ¥340 (dual broth ¥130, chili tare ¥65, nikumiso ¥55, noodles ¥42, garnish ¥48). Price ¥1,100 → margin ¥760 (224%). Volume 18–24/day at Lv4 — niche but high ticket. Beer combo lifts effective ticket to ¥1,520 (+38%). Social viral modifier adds +15% foot traffic on weekends. Price ¥980 minimum to maintain chili ingredient quality perception.
Raymond Howard (95%): +18 pts visible habanero + nikumiso. +12 pts double broth depth. +10 pts beer combo served same ticket. −20 pts if chili oil stale (>20 min hold). −15 pts mild noodle (≥30s). He rewards "Instagram moment" — habanero + steam visible = +10 bonus. Not compatible with Tanaka (forbidden corn/chili crossover).
