I like to eat sashimi and I wish I would live near the sea, where I could buy my fish directly from the boats or go fishing by myself. Most of the time the freshest fish I can get a hold on is trout from the trout farmer in the next village and most of the time I just put it in the smoker. Sometimes we stay with my mother in law who lives in a small seaport and there is the possibility to buy fish from the fishing cooperative but mother in law don't like to eat fish... and she always prepares the food. Therefore I wish I could live near the sea.
I am quite ok with my fish preparation but there are always things to learn and I am not as good as I wish. But there are ways to get better. I found a very nice channel on youtube: http://www.youtube.com/playlist?list=PL23EE4DFC2855121B
Its from the Fukuoka (Japan) officials. Just a few videos on preparing sashimi. I like to watch those very much (only in japanese language). This must be heaven.
