I make this quite a lot. It is in demand at family, work, and club gatherings, and I frequently hear hyperbolic exclamations from those who never had it before. Those who have had it just want to be sure they get it again!
To make this, you need a quantity of Court-Bouillon for Poached Salmon that's enough to cover the fish in the poacher. Paradoxically, for a big fish like this one, you need less than you would for a smaller dinner-size fish in the same poacher, because you need only enough to cover the fish and a big fish takes up more volume. I usually poach a dinner-size piece in a smaller pan.
