Begin by selecting a fresh, high-quality Arctic char. Look for clear eyes, vibrant skin, and firm flesh, ensuring the fish is at its peak for baking. Once you’ve chosen your fish, it’s essential to clean and prepare it appropriately. Rinse it under cold water, pat dry, and ensure all scales are removed.

Next, create the salt crust by mixing coarse sea salt with egg whites until it reaches the consistency of wet sand. This mixture will form the protective barrier that encases the fish, retaining moisture and flavor throughout the baking process.

Step-by-Step Baking Instructions:

1. Preheat the Oven: Set your oven to 400°F (200°C), allowing it to reach the ideal temperature for baking.
2. Prepare the Baking Tray: Line a baking tray with parchment paper to prevent sticking and facilitate easy cleanup.
3. Create a Salt Bed: Spread a base layer of the salt mixture on the tray, forming a bed for the fish to rest on.
4. Stuff the Fish: Gently stuff the cavity of the Arctic char with fresh herbs and lemon slices, infusing it with subtle, aromatic flavors.
5. Encasing the Fish: Place the stuffed fish on the salt base and cover it completely with the remaining salt mixture, pressing gently to mold it to the fish’s shape.
6. Bake to Perfection: Transfer the tray to the preheated oven and bake for approximately 30-40 minutes, adjusting for the size of the fish.
7. Rest and Reveal: Once baked, allow the fish to rest for a few minutes before cracking open the crust to reveal the moist, tender treasure within.
