Fish Straight From the River - Oz

Mud-baked fish is the kind of ancient cooking technique that predates kitchens, made famous in Australian bush cooking and used by countless cultures across the world. A whole fish gets caught fresh from the river, packed in a thick layer of river clay (mud), and buried under hot coals to cook for three hours. The mud acts as both a natural oven and a self-cleaning vessel: when you crack open the hardened clay shell after cooking, the scales and skin come away stuck to the mud, leaving perfectly cooked, smoky-flavored fish underneath.

The technique is simple but trusts you understand a few things. Don’t clean or scale the fish before mud-packing; the mud’s job is to remove all that during cooking. Pack the mud at a moderate thickness, not too thick (the recipe explicitly warns about this) since thick mud either insulates too well or cracks unevenly during cooking. About a half-inch coat works well.

Building the coals properly is the critical preparation. You need a good bed of hot, glowing coals (not flames). Hardwood coals from a substantial fire take 30 to 45 minutes to develop, which conveniently times out with packing the fish.

Cover the mud-packed fish completely with coals. Any exposed mud cooks the fish unevenly. Three hours sounds long for a single fish, but slow cooking inside the mud shell ensures even, gentle heat that penetrates without drying the flesh.

Finish with salt, pepper, and fresh lemon. The clean, smoky fish needs nothing else.

Survival Tips

• Use river clay if you can find it, sandy soil won’t pack properly and disintegrates in the fire
• Test the seal by tossing the packed ball gently, no cracks should appear
• Build up a thick bed of coals before nestling the fish, sparse coals cook unevenly
• Don’t peek during cooking, breaking the mud shell releases the steam that’s doing all the work

Variations

• Stuff the fish cavity with wild herbs or sliced garlic before mud-packing for extra flavor
• Bake on a hot griddle covered with coals if you can’t find proper clay
• Use foil packing as a modern substitute, but the mud method imparts more authentic earthy character
