What's your favorite way to prepare fish when entertaining?
I sometimes shy away from cooking fish for guests because you typically need to cook it last-minute, and because if you get sidetracked, you can easily overcook it. With that in mind, what's your favorite method for cooking fish when entertaining -- saute, roast (high heat, low heat?), poached in olive oil? Since one cooking method doesn't fit all fish, I'll include my favorites: arctic char, halibut, and wild salmon.
