I've eaten pike several times , that was prepared and cooked by my friends wife . She'd fillet it , then remove those horrible little bones , then slice it and deep fry it in batter . It was equal to any chip shop cod. I've also eaten plenty of eels , and my share of barbel when I was younger
I used to bring home perch for another friends wife , but I've never eaten it , and I used to bring back pike up to 3lb , and eels , for another neighbour.
My mom used to like grayling , but I can't remember how she used to cook it.
