Japanese Cuisine

Boiling destroys the live cultures and volatile aromas. Miso soup is always the last step before service. Never hold and reheat miso soup: make it fresh every time. Ratio: 1 tablespoon miso per 200ml dashi.

Dashi from kombu + katsuobushi is already a synergistic combination. Add dried shiitake to the second extraction for a third umami layer. This is the scientific basis behind why Japanese cuisine tastes "deeper" than other cuisines using fewer ingredients.

Binchotan charcoal burns slower and hotter than regular charcoal and imparts no volatile off-flavours. Apply tare in three thin layers: briefly grill each layer before adding the next. The secret of the yakitori bar is the accumulation of tare layers, not one thick coat.

Double frying is the secret to karaage: first fry at 170C cooks the chicken through. Rest for 2-3 minutes, then 1 minute at 180C for the crispy exterior. Katakuriko (not cornstarch) gives a thinner, crispier result that stays crunchy longer.

HACCP: tataki of fish requires freezing treatment (-20C, 24 hours) per EU Regulation 853/2004 for anisakis prevention. Katsuo tataki (bonito) is traditionally done with straw fire (wara-yaki): the straw smoke gives a unique aroma. Cast iron at maximum heat as an alternative.

Niban dashi is the base for nimono (braised dishes), nikujaga and miso soup in traditional kitchens. Never discard: kombu and katsuobushi from niban dashi are still usable as tsukudani (reduction technique) after adding soy sauce, sake and sugar.

Nikiri-mirin: heat mirin to 85C until the alcohol evaporates, then combine. This gives a rounder sweet character. Always three thin layers of glaze rather than one thick one: thin layers caramelise evenly, thick layers burn at the edges before the centre is done.

Ratio: 3 parts dashi to 1 part beaten egg. Steaming above 90C creates holes in the custard (protein overcooking). Never use rolling boiling steam. Professional kitchens: steam oven at 90C or water bath in oven at 150C. Test: insert a skewer, clear liquid means cooked through.

Shiozuke: 2% salt by weight of the vegetable, 30-60 minutes for crisp oshinko. Nukazuke requires a living nukadoko (rice bran bed) that must be stirred daily. HACCP: pH below 4.6 or water activity below 0.85 for microbiological safety in long-term storage.

Shio koji (fermented rice + salt) as a marinade for chicken or fish: 5-7 days at 4C produces a tenderness and umami depth through proteolytic enzymes that hours of regular marinating cannot achieve. Shio koji itself keeps for 6 months refrigerated.

Ikejime-processed fish has lower lactic acid concentration in the muscles, resulting in a cleaner, sweeter flavour and longer ageing window of up to 2 weeks. Compare: conventionally killed fish is optimal for 2-3 days. Spinal cord removal via steel wire (shinkeijime) stops post-mortem muscle contractions completely.

Yanagi-ba (sashimi knife) in one fluid pulling motion: never a sawing movement. Knife always at 30 degrees to the bone: the shallow angle maximises fish yield. For sashimi always cut perpendicular to the muscle fibre for optimal texture.

Always place nori rough side up. Do not spread rice too thick: 5mm, leave 1cm free at the far edge for sealing. Wrap makisu in cling film for uramaki. Wet knife between every cut: a dry knife compresses the roll. HACCP: sushi rice max 4 hours at room temperature.

Sukiyaki raw egg as dipping sauce: the egg tempers the salty-sweet warishita flavour profile and gives a silky coating to the meat. Shabu-shabu: wagyu fat creates a white "bloom" in the broth that enriches the dashi. Drink the broth at the end: it is the essence of the dish.

Preheat teppan for 15 minutes before use. No oil on the plate but on the product: oil on a hot plate burns immediately. After each cook, scrape the plate with a metal spatula and re-oil immediately. The patina of a well-used teppan is a quality indicator.

At 63C: yolk runny, white barely set. At 68C: yolk thick, white custard-like. Thermometer mandatory: a 2C difference produces an entirely different result. Professional: sous-vide at 63.5C for 45 minutes. Serve in warm dashi with tsuyu for the classic ramen topping.

Shred cabbage very fine for binding. After flipping, do not press down: let the steam finish the interior. Katsuobushi on hot okonomiyaki dances from the heat: do not let it cool before serving, the movement is part of the presentation.

Base ratio: soy sauce + mirin + sake (3:1:1), heat to 80C until alcohol evaporates, optionally steep kombu and katsuobushi. Let tare age at least 24 hours before use. Store refrigerated: keeps 6 months. Per ramen bowl: 2-3 tablespoons tare per 300ml broth.

Chill the vegetable slightly before cutting: too warm and the flesh tears, too cold and it snaps. The thumb of the cutting hand controls thickness: constant pressure and even rotation are the principle. The resulting sheet is used for temaki garnish or julienne of uniform thickness.

Otoshibuta (drop lid): a lid slightly smaller than the pot, placed directly on the food. This allows steam to escape, prevents over-rapid reduction and ensures even liquid distribution. Alternative: a circle of baking paper with holes. Nimono dishes are always served in their own braising liquid.

Goma-ae: grind toasted sesame seeds to a paste, mix with soy sauce, mirin and sugar. Always squeeze vegetables after blanching: excess moisture dilutes the dressing. Shira-ae: pressed silken tofu as a base, giving a rich, creamy texture without dairy.

Sanbaizu: rice vinegar + soy sauce + mirin in equal parts. Salt cucumber first (2% salt, 10 min), squeeze out: removes water and adds crunch. Soak wakame, squeeze well. The mildness of rice vinegar is intentional: stronger vinegar overpowers the delicate ingredients.
