Pacific Saury (Kkongchi)

Slender, oily silver fish grilled whole or simmered in East Asian cooking.

Pacific saury is a slim, silvery oily fish abundant in autumn off Japan and Korea. It is most often grilled whole with salt (sanma) or braised, and also sold canned. The rich, fatty flesh has a strong savory flavor and is traditionally eaten with grated daikon and citrus.

Pacific Saury (Cololabis saira) is a slender, silver-skinned fish that commands extraordinary seasonal reverence across Northeast Asia. Known as sanma (秋刀魚) in Japan and kkongchi in Korea, its Japanese name literally translates to 'autumn sword fish' — a direct reference to both its peak season and its distinctive blade-like silhouette. The fish's cultural status rivals that of matsutake mushroom or sweetfish during its brief autumn window, when spawning-ready stocks reach their maximum fat content, transforming what could be a mundane fish into something genuinely exceptional.

The saury's defining characteristic is its exceptionally high lipid content — 10–20% by weight — which peaks in autumn as the fish feeds voraciously before reproduction. This fat renders spectacularly under high heat, basting the flesh from within and creating the deeply savory, almost buttery quality that makes grilled saury (shioyaki) the canonical preparation across Japan and Korea. The flesh is firm with a fine flake, offering a rich, oily taste that is pronounced but not overpowering when properly cooked. Its short lifespan and fast growth rate make it a sustainable choice; well-managed stocks in Japanese and Korean waters carry MSC certification where available.

The fish presents real challenges to unfamiliar cooks: its pungent aroma when cooking (particularly noticeable with less-fresh specimens), the small, bony structure requiring careful eating, and its easy overcooking. These are not obstacles but parameters — score the fish before grilling, cook over high heat to render the fat rather than steam it, and serve immediately with accompaniments like daikon oroshi or sansho pepper that cut through the richness. Master these fundamentals and you'll understand why this humble fish inspires such devotion.

Types & varieties

Japanese Pacific Saury (Sanma)

The most celebrated variety; Hokkaido and Iwate landings are especially prized for their exceptional fat content and sweet, clean flavor.

Korean Pacific Saury (Kkongchi/Gguksae)

Slightly leaner than Japanese stocks but still rich; the standard grilling fish in Korean home cooking.

Pacific Saury (North American)

Smaller specimens with a more pungent flavor; underutilized commercially; increasingly available at Asian markets on the West Coast.

Why Autumn Matters

The saury's oil content is not constant — it fluctuates dramatically with the seasons and the fish's reproductive cycle. In autumn, as the fish prepares to spawn, it feeds heavily on plankton and small crustaceans, accumulating fat reserves that translate directly into flavor and texture when cooked. A September saury is a fundamentally different ingredient than a February saury: the former practically bastes itself on the grill, while the latter can taste lean and unremarkable. Seek out the freshest autumn specimens for the best results.

Addressing the Aroma

Many Western cooks are put off by saury's pronounced cooking aroma, which can register as 'fishy' to unfamiliar noses. This is not a quality defect but rather a function of freshness and preparation. Fresh saury smells far less aggressively than older specimens. Additionally, a 15-minute brine in salted water (roughly 3% salinity) before cooking significantly reduces volatile odor compounds without affecting flavor. Korean cooks routinely employ this technique.

Common uses

Grilled whole with salt (shioyaki) — the canonical preparation in Japan; charring the skin while rendering the fatKorean-style grilled saury (kkongchi gui) with gochujang or doenjang-based marinadesPan-fried fillets or whole small fish, dredged in flourStewed in soy-based braises (Korean kkongchi jorim)Broiled with miso paste (misoyaki style)Added to nabe (Japanese hot pot) for body and umamiCanned or cured for sashimi-style preparations in some regional cuisines

Tips & pitfalls

  • Buy the freshest available: eyes should be clear and bulging, gills bright red, and the flesh should bounce back firmly when pressed.
  • Scale just before cooking, not hours ahead — the skin bruises easily and the fish dries out faster once descaled.
  • For grilling whole: score the thickest part of the body on both sides to allow fat to render and heat to penetrate evenly.
  • Do not overcook: saury is done when the flesh turns opaque throughout and the backbone pulls away cleanly; it goes from perfect to dry in under a minute.
  • If grilling on a wire rack, oil the rack well — saury's skin sticks readily due to its high fat content.
  • In Korean cooking, soaking briefly in salted water (15 minutes) before grilling reduces the strong 'fishy' aroma some people object to.
  • The milt and roe are considered delicacies in Japan; grill them separately or add to the grill alongside the fish.

Substitutes

  • Mackerel (blue or Atlantic)Similar oil content and firm texture; slightly stronger flavor; use 1:1 in most preparations.
  • BluefishComparable fat content and richness; best when grilled or broiled; adjust for stronger, more assertive taste.
  • Sardines (Pacific or European)Smaller and milder; work well for pan-frying or grilling whole; reduce cooking time accordingly.
  • Spanish mackerelGood substitute in Japanese preparations; slightly firmer texture holds up well to high-heat grilling.
