- 500g/1lb 2oz sweet white miso
- 2½ tbsp caster sugar
- 3 tbsp saké
- 3 tbsp mirin (available in Asian supermarkets)
- 1 tbsp light soy sauce
- 4 large sea bream fillets
- 4 tbsp vegetable oil
- 1 lemon, quartered
- 6 green beans, cut in half
- 200ml/7fl oz rice wine vinegar
- 2 tbsp caster sugar
- 1 small green chilli, finely sliced
- 2 large red onions, finely sliced
- 2 baby plum red tomatoes, cut into quarters
- 2 teardrop yellow tomatoes, cut into quarters
- ½ punnet rock chives (subtitute a small bunch of ordinary chives if unavailable)
- salt and freshly ground black pepper
- For the sea bream, place the sweet white miso, sugar, saké, mirin and soy sauce into a bowl and whisk together.
- Rub the sea bream fillets all over with the vegetable oil, then cover generously with the miso mixture. Place onto a dish, cover and transfer to the fridge to marinate for two hours.
- Remove the sea bream fillets from the marinade and place skin-side up onto a clean work surface.
- Thread a metal skewer through each fillet, starting 4cm/1½in from the right-hand side of the tail end, gently folding the fillets to form ripples as the skewer threads up diagonally towards the top of the fillet.
- Repeat with another skewer from the left-hand side of each fish.
- Place wedges of lemon on one end of each skewers.
- Preheat the grill to its highest setting. Place the skewered fish under the grill, skin-side up for 4-5 minutes, until golden-brown.
- Turn the fillets and grill for 4-5 minutes on the other side, or until golden-brown and completely cooked through.
- Remove the lemons from the skewers and slide a fillet onto each plate.
- For the pickled onion salsa, bring a pan of salted water to the boil and add the green beans. Boil the beans for 30 seconds, then drain and plunge into iced water to stop the cooking process.
- Meanwhile, place the rice vinegar and caster sugar into a clean pan and bring to the boil.
- Place the onion and chilli slices into a bowl and pour the hot vinegar over. Cover and set aside for 30 minutes to pickle.
- Place the tomatoes, beans, red onion pickle, rock chives and 1 tsp of the pickling liquid into a bowl and mix well. Season, to taste, with salt and freshly ground black pepper.
- Serve the pickled onion salsa alongside the sea bream fillets.
