Ingredients
- 2 fish (10-12 oz each) whole mackerel or sea bream, gutted and scaled
- 1.5 teaspoons kosher salt
- 1 tablespoon vegetable oil
- 1 lemon fresh lemon or sudachi, cut into wedges
- ¼ cup fresh daikon radish, finely grated
- 2 tablespoons low-sodium soy sauce
Instructions
- 1
Pat each whole fish completely dry inside and out with paper towels — removing all surface moisture is essential for crispy skin. Using a sharp knife, make 3 to 4 shallow diagonal slashes (about 1/8-inch deep) across both sides of each fish, spacing them 1 inch apart. This allows heat to penetrate the thickest parts and helps the skin crisp evenly.

Season the fish generously inside the cavity and on both sides with 1.5 teaspoons of kosher salt, dividing evenly between the two fish. Let the salted fish sit at room temperature for 10 minutes — the salt draws out surface moisture and seasons the flesh throughout.

Preheat a grill (charcoal or gas) to medium-high heat, or set a grill pan over medium-high heat. You want the cooking surface hot enough that a drop of water sizzles immediately on contact. If using a grill pan, let it preheat for 3 minutes.

Lightly brush the preheated grill grates or pan with 1 tablespoon of vegetable oil using a folded paper towel held with tongs — you want just enough oil to prevent sticking without creating smoke.

Place both fish skin-side down on the hot grill. Do not move them — let them cook undisturbed for 4 to 5 minutes. You'll hear a steady sizzle and see the skin turn golden and crispy. The flesh closest to the skin will turn opaque and begin to firm up.

Gently flip each fish using a long fish spatula, sliding it under the belly and supporting the head as you turn. Cook skin-side up for another 3 to 4 minutes. The second side cooks faster since the fish is already hot inside. The fish is done when the flesh at the thickest part near the backbone flakes easily with gentle pressure from a fork, and an instant-read thermometer inserted into the thickest part reads 145°F.

Transfer each grilled fish to a serving plate skin-side up. Finely grate 0.25 cup of fresh daikon radish directly onto each fish using a microplane or box grater — the sharp, peppery raw daikon cuts through the richness of the grilled fish. Drizzle each fish with 1 tablespoon of low-sodium soy sauce.

Serve immediately while the skin is still crisp, with lemon or sudachi wedges on the side. Squeeze the citrus over the fish as you eat — the acidity brightens the delicate, umami-rich flesh.
