# Chef Japanese Cuisine

Japanese cooking is precision + restraint: few ingredients, exact execution, umami doing the heavy lifting. It's the cuisine that TEACHES the rest of your cooking — dashi is a masterclass in glutamate, rice discipline transfers everywhere, and "reveal the ingredient" is the anti-overcooking philosophy. Sushi lives in `chef-world-classics`; this skill is everything around it.

## Umami, engineered (the science core)

- Three synergistic molecules: **glutamate** (kombu, soy, miso, tomato, parmesan), **inosinate** (katsuobushi, meat, fish), **guanylate** (dried shiitake). Glutamate + inosinate together = up to 8× perceived umami — that's WHY dashi is kombu+katsuobushi, not either alone. Use the synergy deliberately in ANY cuisine (`chef-flavor-balance` umami lever cites this).
- **Dashi (10 minutes, changes everything):** kombu in cold water → slow to 60–65°C, hold 10 min (NEVER boil kombu — slime + bitterness) → kombu out, to near-boil, off-heat → katsuobushi in, 2 min, strain. Vegan: kombu + dried shiitake cold-steep overnight. No ingredients? Kombu-cheat: msg-honest pinch + soy — declare it (`chef-ingredient-localizer` for sourcing).
- The seasoning quartet: **soy** (salt+umami), **mirin** (sweet+gloss), **sake** (depth, deodorizes fish), **miso** (fermented body — never boil it hard, kills aroma; whisk in at ≤85°C off-heat).

## The master ratios (memorize three, cook a hundred dishes)
| Ratio (dashi : soy : mirin) | Name/role | Dishes |
|---|---|---|
| 8 : 1 : 1 | Kakejiru — hot noodle broth | Udon, soba soup |
| 4 : 1 : 1 | Tentsuyu — dipping | Tempura sauce, cold noodle dip |
| 1 : 1 : 1 (+sugar pinch) | Teriyaki/nimono base | Glazes, simmered fish/veg, donburi sauce |
All donburi (oyakodon, gyudon) = the 1:1:1 family simmering protein+onion, optionally egg-finished. One ratio = a weeknight repertoire.

## Rice as religion
Short-grain, washed to clear, 1 : 1.1 water, 30 min soak, cook, 10 min steam-rest, cut-fold. Rice quality is judged BEFORE toppings — if the rice is right, dinner is already half-excellent. (Tables in grains guide; sushi seasoning in world-classics.)

## Technique highlights
- **Tempura:** ice-cold batter (weak flour + sparkling/ice water), UNDERMIXED (lumps = law), 170–180°C oil, sparse batches; eat within minutes. Batter overmixing = gluten = bread jacket — the single failure (frying physics in `chef-technique-guide`).
- **Miso soup discipline:** dashi → solids simmered → miso whisked through a strainer OFF the boil; wakame+tofu last. 1 tbsp miso per 200 ml.
- **Tamagoyaki:** sweet-dashi egg rolled in layers — the knife-and-patience drill; rectangular pan optional, small nonstick works.
- **Karaage:** soy-ginger-garlic marinated thigh, potato-starch coat, double-fry (equipment guide's double-fry spec).
- **Tsukemono (quick pickles)** — salt-pressed cucumber/cabbage 30 min = the acid-crunch counterweight; ferment versions in `chef-fermentation-preservation`.
- **Ichiju-sansai** (one soup, three sides) — the meal template: rice + miso soup + one protein + two vegetable sides. It's a balance machine and a meal-prep framework (`diet-goal-nutrition` loves it).

## The aesthetic layer (why it looks/feels Japanese)
Five colors (white/black/red/green/yellow) on the table; five methods across a meal (raw/simmered/grilled/steamed/fried); seasonality as a flavor decision, not decor; NEGATIVE SPACE on the plate; portions small and multiple. Restraint rule for beginners: when a Japanese dish tastes flat, the fix is usually MORE DASHI/umami or acid — not more soy (salt ceiling arrives fast).

## Beginner ramp
(1) Perfect rice + shop-miso soup → (2) teriyaki chicken (1:1:1) → (3) oyakodon → (4) real dashi from scratch → (5) tempura vegetables → (6) an ichiju-sansai dinner. Cues-first instructions per `chef-constraints-adaptation`; every dish lands on a weak single burner (sequencing: rice holds hot 30 min).
