Re: Rainbow Trout
I think variations in the amount of fat in a fish changes how it cooks.
I have cooked farm raised salmon in a smoker, on a grille, even in my Geo. Forman grill and they come out great. Pretty much like the Chinooks I used to catch in Lake Michigan many years ago.
I bought some wild caught salmon (caught off Japan) at Wally World and can't get them to come out well at all. They over marinate in just an hour and require about 50% more time to thoroughly cook. Bleah!
My grandson (the chef) tells me that those fish are too low in fat and that's why they are so hard to prepare. He says not to bother with them.
Maybe that's the trouble with your lake-caught trout. . . not enough fat in the flesh.
