• •Instant-read thermometer
• •Fine-mesh sieve and damp cheesecloth
• •Two broad flexible spatulas

Instructions

1. 1

   Build the court-bouillon

   Combine the very clear fish fumet, the concentrated fish essence, with the Chambertin and salt in a snug, deep sauté pan. This equal proportion is fixed by the dish, so do not stretch the liquid with water if the pan is too broad; move to a narrower vessel instead. Bring the court-bouillon, the poaching liquor, slowly to 175°F to 185°F (80°C to 85°C). It should tremble at the edges without boiling.

2. 2

   Poach at a tremble

   Lower the salmon darnes into the court-bouillon in one layer. A darne is a thick cross-cut steak through the bone, and the center bone stays in place to hold its horseshoe shape. Lay a round of parchment directly on the liquid, cover loosely, and maintain the barest tremble for 10 to 14 minutes. When the center reaches 130°F to 135°F (54°C to 57°C), take the pan off the heat and leave the fish in the liquor until carryover brings it to 145°F (63°C). If the liquid boils and white albumin pushes from the salmon, pull the pan off the burner immediately. The fish is not lost, and the clouded liquor will be rescued during clarification.

   Use an instant-read thermometer through the thickest flesh without touching the central bone. The bone conducts heat differently and gives a misleading reading.
3. 3

   Cool in the liquor

   Set the covered pan in a wide ice-water bath, using about half the ice, and cool the salmon in its court-bouillon for 30 minutes. Transfer the pan to the refrigerator for another 45 to 60 minutes, until the darnes and liquid are thoroughly cold. Cooling in the liquor is not brigade scaffolding; it is part of the dish, keeping the salmon moist while the Chambertin and fumet settle into the flesh.

4. 4

   Skin the darnes

   Lift the cold darnes onto a rack with two broad spatulas and reserve every drop of the cooking liquor. With a small sharp knife, ease away the outer skin and any loose surface fat while leaving the central bone and flesh intact. Remove stray pin bones with tweezers, then blot the surface gently. Cold salmon is firm enough to handle, but it still resents rough treatment.

5. 5

   Clarify the liquor

   Strain the cold cooking liquor through a fine sieve and measure 4 cups (950 ml / about 940 g) into a clean saucepan. Loosen the two egg whites with a whisk, stir them into the cold liquor, and heat very slowly while scraping the pan floor until the proteins gather and rise. Once the raft forms and the liquid reaches its first tremble, stop stirring. Make a small opening in the raft and cook gently for 10 minutes, then ladle the liquid through damp cheesecloth without pressing. Pressing forces the captured particles straight back through. If the aspic liquor remains cloudy, ça se rattrape: cool it completely and repeat the clarification with the additional egg white.

   The clarified liquor should be transparent garnet, not colorless. Chambertin supplies the red; clarity means light passes through it cleanly.
6. 6

   Set the aspic

   Measure 3 cups (710 ml / about 700 g) of clarified liquor. Chill ½ cup (120 ml / about 120 g) over ice, sprinkle the 2 tablespoons (18 g) gelatin evenly across it, and leave it for 5 minutes to bloom. Heat the remaining clarified liquor until hot but never boiling, then stir in the bloomed gelatin until perfectly dissolved. Taste a cooled spoonful and correct the salt if needed. Place a teaspoon on a cold saucer and chill it for 5 minutes; it should set firmly enough to cut while yielding under the tongue. If it remains syrupy, bloom the additional teaspoon of gelatin in a tablespoon of cold clarified liquor and dissolve it into the warm aspic. If it sets too firmly, melt it gently and loosen it with clarified liquor, one tablespoon at a time.

7. 7

   Decorate and glaze

   Pour a ⅛-inch (3 mm) layer of aspic into the chilled glass serving dish and refrigerate it for 10 to 15 minutes, until set but still tacky. Arrange the darnes on this bed. Brush each one with a thin coat of liquid aspic, place the hard-cooked egg-white slices and truffle diamonds in a restrained Belle-vue pattern, then brush again to secure them. Chill for 10 minutes and repeat with two more thin coats, setting each before the next. If the decoration slides, blot the fish and wait until the aspic thickens to the consistency of light syrup. If the bowl sets before you finish, warm it over barely hot water until fluid again.

8. 8

   Fill, chill, serve

   Pour the remaining aspic slowly down the side of the dish until it rises halfway around the darnes. Chill for 20 minutes to anchor the fish, then add the rest until the salmon is just covered and the decoration remains clearly visible beneath the jelly. Refrigerate for at least 2 hours, until fully set. Immediately before serving, nest the glass dish in the remaining crushed ice on a rimmed tray. Keep it cold and bring it to the table with a broad fish slice. À table!

Chef Tips

• •Ask the fishmonger for center-cut salmon darnes of even thickness. Thin tail cuts cook before the center pieces, while boneless portions lose the shape named by the dish.
• •Chambertin is not a decorative word in the title. The source requires it in equal measure with the fumet, and that proportion gives the aspic its color and vinous depth. Another red Burgundy can make a good cold salmon, but it makes a different recipe.
• •The source's white aspic belongs to the clear fish-based family rather than the brown jellies built on meat stock. Chambertin still colors this aspic transparent garnet; bleaching it pale would erase the wine the entry insists upon.
• •Run the cold-saucer test before glazing. Gelatin strength varies, and wine acidity can soften a set. Correcting the warm aspic takes minutes; discovering a loose jelly around decorated salmon takes a much longer face.
• •Keep the serving dish below 40°F (4°C) until it reaches the table, and return leftovers to the refrigerator within 2 hours. A firm white Burgundy is a gentler companion at the table, while a cool red Burgundy carries the flavor of the aspic forward.

Advance Preparation

• •Have the very clear fish fumet finished and cold before beginning. It may be prepared up to 2 days ahead and kept refrigerated in a covered container.
• •The completed dish may be glazed, filled, and chilled 1 day ahead. Cover it only after the aspic has fully set so wrapping cannot mark the surface.
• •Cut the egg-white and truffle decorations earlier on the day of service and keep them separately covered and cold. Nest the serving dish in fresh crushed ice only when it is time to carry it to the table.
