Poached Whole Salmon
When poaching a large whole fish, place it in cool liquid first and then slowly bring the liquid to the proper temperature to result in an even texture inside and out. Adding the raw fish to hot liquid would cause the outside to overcook before the inside is cooked. Court Bouillon (page 231) is the traditional poaching liquid for seafood, imparting gentle flavors to the fish without being the least bit overpowering. For the prettiest presentation, remove the skin from the fish while it is still warm, as it will slip off more easily than when cold. A whole fish is always an impressive sight at the table, but even more so when poached and then wrapped in thin ribbons of cucumber, the plump pink fish in stark contrast to the bright-green ribbons.

Preparation
Step 1
Prepare poacher Pour the Court Bouillon into a fish poacher and set the poacher over two burners on the stove. Lower the rack so it rests on the vegetables (in the court bouillon), then lay salmon on rack (trim the tail if necessary to fit inside). Add enough cool water to cover the fish completely; or, if only a small bit of fish is showing, you can cover it with a piece of parchment paper (cut to fit inside poacher).
Step 2
Poach fish Bring the liquid to a simmer over medium-high heat, then immediately reduce heat to medium-low. Check temperature with a candy thermometer and adjust heat so it is between 165° and 180°F (very few bubbles will break the surface but there should be steam coming from the surface). Poach salmon, adjusting heat as necessary to maintain the proper temperature, until an instant-read thermometer inserted into the thickest section registers 130°F (fish will continue cooking off heat). You can also test by inserting a knife into the flesh along the backbone; the flesh should still be slightly translucent and offer little resistance. The cooking time should be about 5 minutes per inch of thickness (once liquid has reached a simmer). Remove poacher from heat and allow it to cool until you no longer see any steam, about 1 hour. Lift the rack with the salmon from the poacher and set it over a large pan (or the sink) to allow the salmon to drain until just cool enough to handle, about 30 minutes.
Step 3
Prepare fish for serving Transfer salmon to a clean work surface. Use your fingers and a paring knife to pull and scrape off the skin from the top side of the fish. Use the back of the knife to scrape off any brown areas from the surface. Using two large spatulas, carefully slide the salmon onto a serving platter. At this point, the salmon can be covered with plastic wrap and refrigerated for up to 4 hours.
Step 4
Serve Slice the cucumber lengthwise into very thin strips. Arrange the strips diagonally across salmon, spacing them about 1 inch apart, and tuck the ends underneath so they appear to wrap around the fish. Garnish with watercress. Separate into pieces and serve sauce and lemon wedges on the side.

Step 5
The salmon is garnished with a mixture of watercress and Upland cress (a member of the mustard family with a sharp, spicy flavor), which are also used in the accompanying sauce. You can find Upland cress (also called English cress or garden cress) at farmers’ markets, or use all watercress instead.

Step 6
A poacher is just the right size and shape for cooking a large whole fish, such as the salmon in this recipe. For smaller whole fish, a roasting pan fitted with a wire rack can be used instead.
Step 7
To make the paper-thin strips of cucumber that appear to wrap around the fish, a mandoline is the best tool. A Japanese-style mandoline, such as Benriner, is inexpensive and sold at most kitchen supply shops. A vegetable peeler can be used instead, but it will not be able to produce the same uniform thickness as the mandoline.
CUCUMBER, CRESS, AND CAPER SAUCE
Step 8
Peel and finely chop 1 English cucumber, then toss with 1 1/2 teaspoons coarse salt and 1 tablespoon each Champagne vinegar and small (nonpareil) capers that have been rinsed and drained. Set aside for 5 minutes, then stir in 1 cup sour cream and 1/2 cup finely chopped cress (use half watercress and half Upland cress, if you can find it). Season with freshly ground pepper and more salt. Serve immediately, or cover and refrigerate up to 4 hours before serving. Makes about 2 1/4 cups.
