Are you sure you want to cook unagi? Even almost no Japanese would cook the unagi at home as it's nearly impossible for the amateurs to bone it.

I will get back if I find a site explaining what you need. But one question. In what form do you get unagi? I'm taking it for granted that you get them alive, and that's why I mentioned the boning. But if you get them boned and perhaps pre-cooked without the sauce, things will be much easier.
