Ingredients

Instructions

  1. Step 1: Season 4 barramundi fillets with 1 tsp salt and 1/2 tsp black pepper evenly on both sides.
  2. Step 2: Place 1/2 cup all-purpose flour in a shallow dish, 1 large beaten egg in another, and 1 cup finely chopped macadamia nuts in a third.
  3. Step 3: Dredge each fillet first in flour, then dip into the beaten egg, and finally press into the macadamia nuts until well coated.
  4. Step 4: Heat 3 tbsp butter in a large skillet over medium heat until melted and sizzling.
  5. Step 5: Add the crusted fillets and cook for 3-4 minutes per side until the crust is golden brown and the fish flakes easily with a fork.
  6. Step 6: Remove fillets and keep warm. In the same skillet, add 1/2 cup heavy cream and 1 tsp lemon myrtle powder, stirring constantly over low heat for 2 minutes until the sauce thickens slightly.
  7. Step 7: Stir in 2 tbsp fresh lemon juice, then spoon the sauce over the fillets and serve immediately.
