Halibut Simmered in Soy and Sake

A quick and simple dish, one that produces a beautiful sauce to use on white rice. Halibut is ideal here, but swordfish steaks are great too, and you can even make this preparation with thick white fillets of grouper, red snapper, or sea bass.

Use dashi (which can be prepared in just a few minutes) if at all possible, chicken stock if not.
