Why This Grilling Method Works
Charcoal grilling creates incomparable smokiness that supermarkets air fryers can’t replicate. The indirect heat side gently cooks fish while the direct zone sears the outside, locking in juices. The Oklahoma Joe-style two-zone fire ensures perfect doneness without drying the fish.
