Another successful trip!
Cooking 'em is easy enough . . . dip the fillets in some egg, flour and a little melted butter, and fry 'em. "Poor man's shrimp" is what I've heard them called serve this way.
The hassle is filleting them . . . which (I willl confess) I am not proficient at.
A friend of mine can consistently get beautiful butterfly shaped fillets that saves every bit of the "jelly like" meat that's the "good stuff."
By contrast, when I do it, I end up with dribs and drabs of meat that looks like it's been run through a wood chipper, and (worse yet) fear I lose at least 20% of the good stuff.
I've heard there's a way to cook them without filleting them so fastidiously, but if there is, I don't know what it is.
Cooking trout is definitely a lot easier - - just clean them and cook them with the back bone still in, and then pull the back bone out. (There's some debate whether it's better to keep the heads on to have something to grab when removing the spine. I favor that approach, but I know others who have tried it both ways and claim it really doesn't matter).
