Japan — Pacific saury fishing tradition ancient; seasonal autumn significance established through the Edo period food calendar
Sanma no shioyaki (salt-grilled Pacific saury) is one of Japan's most quintessential autumn preparations — a seasonal event as much as a recipe, where the appearance of the first fat, oil-rich sanma (Pacific saury, Cololabis saira) at markets signals autumn's arrival and prompts a nationwide return to the fish grill. Sanma is caught during autumn migrations when the fish are at their fattest, their skin darkly iridescent and their flesh dense with the specific omega-rich oil that makes them both extraordinary eating and extremely fast-burning on a grill. The preparation could not be simpler: the whole fish (typically 150–200g, about 30cm long) is scored lightly on both sides, heavily salted inside and out, and grilled over charcoal (binchotan ideally) until the skin is blistered and slightly charred, the fish is cooked through, and the rendered fat dripping onto the coals creates smoke that adds additional flavour. This dripping fat-smoke interaction is a central feature of sanma shioyaki — the grill is positioned to allow this to happen without causing flare-ups. The traditional accompaniments: a small pile of grated daikon (to cleanse the palate from the fat), sudachi or kabosu citrus halved alongside (squeezed over the fish), and soy sauce. The sanma is eaten from head to tail — including the head, fin, and the slightly bitter intestines (harawata), which are considered a delicacy that enhances rather than distracts from the eating experience.
Sanma at peak autumn season is extraordinary — the flesh is dense with oil that renders beautifully under charcoal heat, the skin crisps to a shatteringly thin shell, and the deliberately retained intestine bitterness creates the counterpoint that makes each bite of rich, fatty fish cleaner than it would otherwise be.
Salt concentration must be generous — sanma has sufficient fat to absorb significant salt without becoming unpleasantly salty. The bitterness of the intestines is the flavour counterpoint to the fat richness — do not remove before eating. Charcoal distance is calibrated to allow fat drip without flare-up — the smoke from the fat drip contributes essential flavour. Timing: approximately 5–7 minutes per side over medium-high charcoal, depending on fish size.
For the definitive sanma experience: salt the whole fish 20 minutes before grilling, pat the surface completely dry (wet surface steam-cooks rather than charring). Score the skin in a crosshatch pattern — this allows fat to render through the skin surface more readily and creates more crisped surface area. The sanma's highest-fat sections (near the belly) need more careful heat management — the belly fat can cause flare-up if positioned too close to coals. Squeeze sudachi directly over the fish at the table just before eating the first bite — the citrus fragrance released by the heat of the fish is an integral part of the eating experience.
Removing the intestines before cooking (missing the defining bitter-fat contrast). Cooking over insufficient heat — sanma requires high, direct charcoal heat for proper skin crisping and fat rendering. Under-salting — the salt must penetrate through the fish, not just season the exterior surface. Serving without daikon and citrus — the fat richness requires these accompaniments to achieve balance.
