Ingredients

Instructions

  1. Step 1: Preheat the grill to medium-high heat (around 400°F). Brush 4 hoki fillets with 2 tbsp olive oil and season evenly with 1 tsp salt and 1/2 tsp black pepper.
  2. Step 2: Place the fillets skin-side down on the grill and cook for 4-5 minutes without moving until the edges begin to crisp, then carefully flip and cook for another 3-4 minutes until opaque and flaky.
  3. Step 3: While the fish grills, mix 4 tbsp unsalted butter with 1 tsp lemon myrtle powder, 1 tbsp fresh lemon juice, and 2 tbsp chopped fresh parsley in a small bowl until smooth and aromatic.
  4. Step 4: Remove the hoki fillets from the grill and immediately spoon 1 tbsp of the lemon myrtle butter on each fillet, allowing it to melt over the hot fish before serving.
