Paperbark (melaleuca bark) wrapping is an Indigenous Australian technique that creates a sealed steam environment around food while imparting a subtle smoky, tea-like flavour. The bark is soaked until pliable, wrapped around fish or meat, tied, and cooked over coals or in an oven. The earth oven (ground oven or kup-murri) is a pit lined with heated stones, layered with wet bark and leaves — the original steam oven. Both techniques cook through trapped steam and gentle, even heat.
Paperbark must be soaked in water for at least 30 minutes until flexible — dry bark cracks and burns. The wrap should be tight enough to seal but loose enough to allow steam expansion. Food is seasoned before wrapping. Cooking temperature is moderate — the bark chars slowly on the outside while steaming the food inside. The bark contributes tannins and aromatic compounds from the melaleuca oils. For oven cooking: 180-200°C for fish (15-20 minutes depending on thickness), higher for poultry. The bark will darken and become fragrant — that's correct.
Paperbark-wrapped barramundi is the signature dish of modern Australian cuisine. Season the fish with lemon myrtle and native pepper, brush with macadamia oil, wrap, tie with kitchen string, and grill over medium coals or bake at 190°C. The fish steams in its own moisture, infused with the smoky-sweet bark aromatics. The presentation — unwrapping at the table — is part of the experience. If paperbark isn't available, banana leaves create a similar steam effect with a different flavour profile.
Not soaking bark long enough — it cracks and the seal breaks. Wrapping too tightly — no room for steam expansion. Direct high flame — the bark should char slowly, not ignite. Opening too early to check — you break the steam seal. Using treated or decorative bark — only food-grade melaleuca bark.
