Catch some small to medium pan sized fish, and clean them asap. The intent here is to get the fresh catch to pan as quickly as possible.
Dust the cleaned catch with flour, and drop it into a sufficiently heated pan, with a small amount of oil, preferably an oil that has a minimum of its own flavor.
Add salt and pepper to taste as it cooks, flip over when golden brown .
While the 2nd side is being cooked in the pan, use fork to eat the side that is already cooked (now face up) and is obviously still hot. This process usually works well for one or two individuals, but large parties are tough to handle in this manner.
Once the upside is devoured, the side being cooked is about done and merely needs flipping over, and eating may again resume.
There you have it, super fresh pan fish that is HOT while you eat it. Nothing fancy though, just good fish flavor. Yes, you are eating from the pan, but camping and fishing is supposed to be a fun experience.
