Sanma shioyaki is the quintessential Japanese autumn dish, featuring whole Pacific saury grilled simply with coarse salt to highlight its rich, oily flesh. The fish develops a smoky, crispy skin while the interior stays tender and moist, served traditionally with grated daikon to cut through the richness. It's a minimalist preparation that lets the natural flavor of the seasonal fish shine.

Ingredients
For the fish
- 4 whole Pacific saury (sanma/pike mackerel), about 130-150 g each, gutted and cleaned
- 2 tablespoons coarse sea salt
- 1 teaspoon vegetable oil, for brushing the grill
For the condiments
- 300 g fresh daikon radish, peeled
- 4 tablespoons soy sauce
- 1 lemon or 2 sudachi, cut into wedges
- 2 scallions, finely chopped (optional)
- 1 tablespoon grated fresh ginger (optional)
Directions
- Rinse each fish under cold running water and pat completely dry inside and out with paper towels. Using a sharp knife, make 2 to 3 shallow diagonal slits across the thickest part of each side so the heat penetrates evenly.
- Sprinkle the coarse sea salt generously over both sides of each fish and inside the cavity, rubbing it in lightly. Set on a wire rack and let rest at room temperature for 15 minutes so the salt draws out surface moisture; this ensures crisp skin.
- Meanwhile, finely grate the daikon radish using the smallest holes of a box grater. Gather the grated daikon into a small mound between your palms and gently squeeze out the excess liquid just before serving to keep it light and fluffy.
- Preheat a charcoal grill to medium-high heat, or heat a cast-iron grill pan over medium-high for 5 minutes until very hot. Lightly brush the grates or pan with vegetable oil to prevent sticking.
- Place the fish on the grill at a 45-degree angle to the grates to create attractive sear marks. Cook undisturbed for 4 to 5 minutes until the skin is blistered, lightly charred, and releases easily from the grill.
- Carefully flip each fish using two spatulas and grill the second side for 3 to 4 minutes until the skin crisps and the flesh near the spine flakes easily and turns opaque (internal temperature 145°F / 63°C).
- Transfer the grilled fish to a warm serving plate and let rest for 1 minute. Mound a generous spoonful of grated daikon beside each fish and arrange lemon or sudachi wedges on the side.
- Serve immediately with small dishes of soy sauce. The traditional way to eat is to add a spoonful of grated daikon into the soy sauce, then dip the fish to taste; squeeze citrus over the top as desired.
Cook’s Notes
- Choose saury with bright, clear eyes, firm flesh, and shiny silver-blue skin; these are signs of peak freshness. Frozen whole saury should be thawed overnight in the refrigerator and patted very dry.
- Traditional binchotan charcoal gives the fish its signature smoky aroma. If using a broiler, position the rack 4 to 6 inches from the heat and watch carefully to prevent the fatty skin from igniting.
- The grated daikon (daikon oroshi) is not optional in this dish – its sharp, slightly bitter juice cuts through the rich oiliness of the fish and aids digestion.
- Eat the fish hot off the grill for the crispiest skin. In Japan it is customary to eat the entire fish, including the tender bits near the head and collar.
- To check doneness, insert a chopstick near the spine – it should slide in easily and feel hot to the touch when pulled out.
