Britchaser,
To me the cedar seems to give the meat a subtle, smoky sweetness compared to some of the other woods.
Bob,
I use the lump hardwood charcoal instead of briquettes. Like kiotehntr said, gas or charcoal grills will work. I usually soak the plank for about 24 hrs. As a matter of fact, you can soak them in fruit juices, bourbon, etc. I did try soaking one in peach nectar for some pork loin and it was good. Also, don't let the plank catch on fire, kind of ruins the whole experience.
This is the recipe that really got us hooked on using a plank:
Grilled Cedar-Plank Salmon
1 untreaded cedar plank (soaked)
1/2 Cup Sun Dried Tomato Vinaigrette Dressing
1/4 Cup finely chopped fresh parsley
1/4 Cup finely chopped sun dried tomatoes
1 Tbsp vegetable oil or olive oil
1 Salmon fillet (2 lb). 1 inch thick, skin removed
Preheat grill to medium heat and mix dressing, parsley, and sun dried tomatoes
Rub oil on one side of plank
Place salmon on oiled side of plank
Place plank w/salmon on grill
Cook 10-15 minutes
Brush salmon with dressing and cook another 10-15 minutes.
Eat and enjoy
