Instructions

  1. Step 1: Preheat oven to 275°F (135°C). Rub 4 barramundi fillets (5 ounces each) with 2 tablespoons olive oil, 1 teaspoon sea salt, and 1/2 teaspoon black pepper.
  2. Step 2: Place fillets on a lined baking tray and slow-cook in the oven for 20-25 minutes until just opaque and flaky.
  3. Step 3: In a bowl, combine the pulp of 3 peeled finger limes, 1 cup diced cherry tomatoes, 1/4 cup chopped fresh coriander leaves, and 1 finely chopped small red chili to create a fresh salsa.
  4. Step 4: In a small skillet over medium heat, melt 2 tablespoons unsalted butter. Add 1/3 cup chopped macadamia nuts and 1 teaspoon lemon zest, toasting for 3-4 minutes until golden and fragrant. Remove from heat.
  5. Step 5: Serve the slow-cooked barramundi topped with finger lime salsa and sprinkled generously with the macadamia crumble for texture and nuttiness.
