Grilling over charcoal (sumiyaki) has been central to Japanese cooking since the Yayoi period. Shio-yaki, with its absolute minimalism — just salt on excellent fish over clean charcoal — reflects the Shinto aesthetic of uncorrupted nature. Teriyaki (teri = lustre from the glaze, yaki = grilled) developed as a technique for fish and poultry that benefits from the sweetness of mirin and the Maillard development of soy. The lacquered surface that gives teriyaki its name is a visual indication of correct technique.
Yakimono — grilled things — encompasses two fundamental approaches: shio-yaki (salt-grilling) and teriyaki (glazed grilling). They are not interchangeable styles or preference choices. Shio-yaki is the correct method for fish of exceptional quality where the natural flavour must be the entire dish. Teriyaki is the correct method for fish or chicken where the Maillard glaze is the dish. The choice is made before the flame is lit, and neither apologises for the other.
Shio-yaki is the purest Maillard application in Japanese cooking — nothing between the protein and the heat except salt, which promotes surface drying and therefore faster, more even browning. As Segnit notes, salt and fish is not seasoning in the conventional sense — it is a textural and flavour transformation agent. The teriyaki glaze adds Maillard compounds from the soy (amino acids + sugars) and the sweetness of mirin, creating a flavour architecture that frames the fish's natural character rather than replacing it — provided the glaze is thin and applied correctly.
**Shio-yaki:** - Salt: fine sea salt applied 30–60 minutes before grilling for thin fillets; 1–2 hours for whole fish. The salt draws moisture to the surface, which must be dried off before grilling. This firming of the flesh is the technique. - Fire: high heat, clean charcoal (binchōtan preferred). The fish should cook quickly — the surface chars faintly while the interior remains moist. - The presentation side goes down first — grilled second, it faces up at service with perfect grill marks unmarked by the spatula. - Do not move the fish until it releases naturally. Force-turning tears the skin. **Teriyaki:** - Sauce: soy sauce, mirin, sake, and sometimes sugar in a ratio of approximately 1:1:1 with adjustments by application.

A coat applied to raw protein burns before the surface reaches its correct temperature. - Each coat is applied, allowed to set for 30–45 seconds in the heat, and the next coat follows. - Correct finish: a lacquer-like surface with visible highlights, not a wet or sticky coating. Decisive moment: **Shio-yaki:** The moment the skin sets and releases from the grill without sticking. The fish should be turned once — presentation-side down first, then flipped. When the second side is placed down and the fish releases immediately when nudged, the technique is working correctly. **Teriyaki:** The final glaze application — when the sauce hits the surface and sizzles, sets, and develops a visible sheen within 45 seconds. If the glaze runs off rather than setting, the temperature is insufficient. If it darkens immediately to near-black, the temperature is too high. Sensory tests: **Shio-yaki sight:** The finished fish should show delicate char marks at the high points of the skin with golden browning across the surface. The skin should be visibly taut and crisp. Any pale, soft-looking skin indicates insufficient heat or insufficient salt firming. **Teriyaki sight:** The lacquer surface — the literal teri. A mirror-like quality to the glaze, highlights visible. Not wet, not matte. The colour: deep amber to mahogany, never black. **Shio-yaki smell:** The smell of clean fish and sea salt caramelising over charcoal — pure, direct, specific to the fish species. This smell is different from anything else. **Both — the flesh test:** Press the thickest part gently. It should give with moderate resistance and spring back partially. Full spring-back: undercooked. No spring-back: overcooked.
— **Skin sticking and tearing:** Grid not hot enough before fish was placed, or fish was moved before the skin set. — **Teriyaki burning on first application:** Sauce applied too early to raw protein. Wait until the protein surface is cooked and the temperature has moderated. — **Teriyaki wet and running:** Temperature too low for glaze to set, or too many applications too quickly. — **Shio-yaki interior raw, exterior charred:** Heat too high — common with thick whole fish. Use moderate heat for longer cooking, or finish in an oven after initial high-heat charring.
