Ever been hungry camping, and about the only thing you can catch is perch? Found a way to cook them with out pots or pans. Simple. Gut the perch. Pack mud around perch, throw in fire, coals. Wait till mud is hard, break baked mud open (usually you get skin on one side, meat and skin on the other). The mud acts as an oven, and the perch is cooked completely when the mud is dried.
