Tekobo, to answer your question, NO.
I also read a lot of reviews and like you very often use that same idea - I'll try it out myself.
There weren't enough reviews on the UK site to allow me to judge and the book here is $45 and space is limited. I'd like to see the recipes to help me decide. If 80% are fish or internal organs recipes it probably isn't going to work for me. If I get 2 or 3 great recipes I'd consist it a winner.
