Saumon Froid, ou Darne de Saumon Froid en Belle-vue

Ingredients

Equipment Needed

• •12-inch (30 cm) wide, deep sauté pan or small roasting pan
• •Instant-read or probe thermometer
• •Medium heavy-bottomed saucepan
• •Fine-mesh sieve and cheesecloth
• •Wire rack set over a rimmed tray
• •Close-fitting 1½-quart (1.4 L) oval clear glass serving dish
• •Broad tray large enough to hold the glass dish and crushed ice
• •Small sharp knife and fish slice

Instructions

1. 1

   Clarify the fish stock

   Combine the fish stock with ½ cup (120 ml) of the wine in a saucepan and let the mixture become completely cold. Whisk 2 egg whites only until loosened, not foamy, and stir them into the cold stock. Heat very slowly, stirring across the bottom until the whites gather and begin rising into a raft. Stop stirring, open a small vent in the raft with a spoon, and hold the liquid at the barest simmer for 15 minutes. Ladle it gently through a fine sieve lined with damp cheesecloth, without pressing the raft. Pressing forces the captured particles straight back into the aspic.

   If the strained stock is not brilliant, pass it through fresh damp cheesecloth once more. Clarity is not decoration here. It is the entire meaning of belle-vue.
2. 2

   Set the aspic strength

   Sprinkle the gelatin evenly over the ½ cup (120 ml) cold blooming water and leave it for 10 minutes, until every grain is swollen. Stir the bloomed gelatin into the hot clarified stock off the heat, then taste and add up to 1 teaspoon of salt. Cold dulls seasoning, so the liquid should taste slightly more vivid than you want at the table. Spoon a tablespoon onto a chilled saucer and refrigerate it for 5 minutes; it should set firmly but melt cleanly on the tongue. Cool the remaining aspic until it is fluid and lightly syrupy. If it sets in the bowl, warm it gently over lukewarm water. If it runs like water, chill it for another 5 minutes. Ça se rattrape.

   Never boil the aspic after adding gelatin. Hard boiling weakens the set and flattens the clean fish flavor.
3. 3

   Make the poaching liquor

   Put 8 cups (1.9 L) of the remaining water and 1 cup (240 ml) of the remaining wine into a wide pan with the onion, carrot, parsley stems, bay leaf, peppercorns, and poaching salt. Simmer gently for 15 minutes, then lower the temperature to 175°F (80°C). The pan should hold the darne without bending it, with the liquid covering the fish by about 1 inch (2.5 cm). A wide sauté pan or small roasting pan is the honest home equivalent of a fish kettle.

4. 4

   Poach the darne gently

   Lower the salmon into the liquor and hold the temperature between 167°F and 176°F (75°C and 80°C). The surface may tremble, but it must never boil. Poach for 25 to 35 minutes, depending on thickness, until a thermometer inserted into the thickest fillet reads 140°F (60°C). Lift the fish carefully onto a rack, rest it for 5 minutes, and confirm that carryover heat brings the center to 145°F (63°C). Boiling would contract the flesh, force out its moisture, and leave the chilled salmon dry.

   If the liquor begins bubbling, pull the pan from the heat immediately and add a small ladle of cold water. The salmon is unharmed if you catch it quickly.
5. 5

   Chill and skin

   Let the darne drain and cool for 20 minutes, then refrigerate it uncovered until thoroughly cold, about 1½ hours. Support each fillet with one hand while lifting away the skin with the tip of a small knife. Remove the thin gray layer immediately beneath the skin without cutting into the coral flesh, but leave the central bone and the connection at the belly intact because they hold the darne upright. Set it on its belly edge on a cold tray and blot every surface dry. Aspic will not cling to wet fish.

6. 6

   Prepare the decoration

   Bring the remaining 2 cups (475 ml) water just below a simmer in a small saucepan. Slide in the remaining egg white and poach it gently until evenly opaque, about 3 minutes. Lift it out, cool it in cold water, and blot it dry. Cut small diamonds, crescents, or narrow leaves from its smoothest parts. Arrange the white egg, black truffle, chervil, and tarragon across both fillets in a simple repeating pattern, leaving enough coral salmon visible for the decoration to breathe.

7. 7

   Fix the garnish

   Spoon a few drops of lightly syrupy aspic over each piece of decoration, using only enough to fasten it to the salmon. Refrigerate the darne for 5 minutes, until the garnish no longer shifts when the tray is moved. If the herbs curl or the truffle slides, the aspic is too warm; chill it briefly and fix the loose pieces again. Do not chase them around with your fingers. A drop of properly cooled aspic does the work.

8. 8

   Build the clear veil

   Spoon a very thin coat of aspic over the entire darne and refrigerate it for 4 to 6 minutes, just until set. Repeat with 5 to 7 thin coats, turning the tray as needed so both decorated fillets, the cut face, and the upper edge receive an even veil. One heavy pour will trap bubbles, drag away the garnish, and set in thick ridges. Repeated thin coats are not brigade ceremony. They are the dish. If a coat lands in lumps, warm the aspic gently until fluid again; if a bare patch remains, cover it with the next coat.

9. 9

   Encase the salmon

   Transfer the glazed darne to the close-fitting clear glass dish and stand it upright on its belly edge. Pour the remaining cool, fluid aspic slowly around the fish, not directly over the decoration. If the darne begins to lean, support it between two chilled spoons, add only ½ inch (1 cm) of aspic, and refrigerate until that anchor sets before filling the dish to the brim. Chill for at least 2 hours, until the jelly is completely firm and transparent.

10. 10

    Present it over ice

    Spread the crushed ice in a broad tray and nest the glass dish securely into it just before serving. Wipe the rim so the aspic remains brilliant and the cold glass shows only fine beads of condensation. Cut through the jelly with a sharp knife, then lift portions from each fillet away from the central bone with a fish slice. The salmon is generous, the aspic trembles, and nothing needs disguising. À table!

Chef Tips

• •Choose the glass dish first and take its inside measurements to the fishmonger. Ask for a thick center-cut darne from a large salmon, scaled but left skin-on and intact at the belly. A close fit steadies the fish and keeps you from making a bucket of aspic.
• •If fresh truffle is not in season, use a good whole preserved black truffle. This is precisely the work of the classical pantry, and an honest preserved truffle is better than a tired fresh one with no perfume left.
• •Clear fish stock matters more than expensive salmon. Avoid a dark roasted stock or one strongly flavored with shellfish, because both obscure the coral fish and the delicate herbs beneath the aspic.
• •Keep the finished dish at or below 40°F (4°C). The crushed ice is presentation and temperature control together, but return leftovers to the refrigerator promptly and discard anything held above 40°F (4°C) for more than 2 hours.
• •Serve with a mineral dry white such as Chablis or Sancerre. The aspic and herbs want freshness and acidity, not oak or sweetness.

Advance Preparation

• •The aspic can be clarified and set up to 2 days ahead. Refrigerate it covered, then melt it gently over lukewarm water without boiling and cool it to the syrupy glazing stage.
• •The salmon can be poached, chilled, and skinned the day before assembly. Keep it covered once cold so its surface does not dry, then blot it carefully before decorating.
• •The completed belle-vue may be assembled up to 24 hours before serving. Cover the dish without letting the wrapping touch the aspic, keep it refrigerated, and add the crushed ice only when it goes to the table.
• •Do not freeze the finished dish. Freezing damages both the salmon and the gelatin structure, leaving the aspic cloudy and wet when thawed.
