Ingredients

Instructions

  1. Step 1: Prepare three shallow dishes: one with 1/2 cup all-purpose flour, one with 2 beaten eggs, and one with 1 cup chopped macadamia nuts. Season the 4 barramundi fillets with 1 tsp salt and 1/2 tsp black pepper.
  2. Step 2: Dredge each fillet first in flour, shaking off excess, then dip into the beaten eggs, and finally press firmly into the macadamia nuts to coat completely.
  3. Step 3: Heat 3 tbsp butter and 2 tbsp olive oil in a large skillet over medium heat until the butter foams.
  4. Step 4: Add the crusted fillets and cook for 4 minutes per side until golden brown and the fish flakes easily with a fork.
  5. Step 5: Meanwhile, in a small saucepan, combine 3 tbsp lemon juice, 1 tsp ground wattleseed, and 1/4 cup heavy cream. Heat gently over low heat for 3 minutes until warm and slightly thickened.
  6. Step 6: Serve the barramundi fillets drizzled with the lemon wattleseed sauce alongside steamed greens or salad.
