Actually, I've come to a conclusion: the above-referenced method is SECOND "good as it gets."
Absolutely "good as it gets" is to put the skillet over a fire as soon as the fish comes out of the water. By the time you gut & gill it the pan will be ready. Then proceed as above. There is absolutely nothing to match a beautiful morning in the middle of nowhere, with trees all around, on the banks of a babbling mountain stream or crystal-clear mountain lake, with a crackling fire going and the wonders of the outdoors hitting each and every one of your senses ~ a perfect setting for this meal.
