"This is a really simple and light dish perfect for spring," says Rodney Dunn. "The components can all be prepared ahead of time. At the restaurant we use whatever fish the fishermen have caught and so can you - the best white-fleshed fish you can buy - freshness is everything with this dish."
- 2 leatherjacket fillets (about 190gm each), or other white-fleshed fish such as snapper or blue-eye, skin removed
- 55 gm sea salt
- 45 gm caster sugar
- 1 spring onion, thinly sliced
- Thinly sliced mustard leaves, miner’s lettuce and borage flowers, to serve (see note)
- 2 tbsp sunflower seeds
- 1 tbsp sesame seeds
- 1 tbsp nigella seeds
- 2 tbsp buckwheat
- 250 ml vegetable oil (1 cup)
- 50 gm finely chopped onion
- 1½ tbsp rice vinegar
- 1½ tbsp light soy sauce
- 1 tsp finely grated horseradish
- 1 garlic clove, thinly sliced
- 70 ml grapeseed oil
- 1 tbsp sesame oil
- 1Trim fish into 8 portions and transfer to plates. Combine salt and sugar, scatter over both sides of fish, cover with plastic wrap and refrigerate for 2 hours.
- 2For toasted seeds, dry-roast sunflower, sesame and nigella seeds over medium heat until fragrant (6-7 minutes). Bring a small saucepan of water to the boil, add buckwheat and cook until just tender (7-8 minutes). Drain and pat dry with paper towels. Heat oil in a small saucepan to 180°C and deep-fry cooked buckwheat until golden and crunchy (6-7 minutes; be careful, oil will spit). Transfer to a plate lined with paper towels using a slotted spoon, cool, then combine with seeds. Toasted seeds will keep in an airtight container for up to a week.
- 3For horseradish vinaigrette, process all ingredients except oils in a blender until combined, then, with the motor running, drizzle in oils. Season to taste and refrigerate until required.
- 4Brush curing mix off fish and pat dry with paper towels. Transfer to serving plates, drizzle with vinaigrette, scatter with spring onion, leaves, flowers and toasted seeds, and serve.
Mustard leaves and borage flowers are available from farmers’ markets and specialist greengrocers. If they’re unavailable substitute rocket and other edible flowers, such as chive flowers.
