Sole à la Royale

Ingredients

Equipment Needed

• •Wide lidded fish poacher or 18-inch (46 cm) shallow roasting pan
• •1-inch (2.5 cm) melon baller
• •Large oval heatproof serving platter
• •Two broad fish spatulas
• •Small heavy saucepan
• •Fine-mesh sieve
• •Instant-read thermometer

Instructions

1. 1

   Ready every component

   Heat the oven to 375°F (190°C). Bring the cooked mushrooms, poached quenelles, crayfish tails, and truffle slices out of the cold for about 30 minutes. Keep them covered so their surfaces do not dry. Fill the serving platter with hot water and leave it to warm while you work. Normande sauce must already be prepared because the source treats it as a finished component, just as a brigade would.

2. 2

   Turn the potato balls

   Use a 1-inch (2.5 cm) melon baller, the honest home equivalent of the round spoon-cutter, to cut 20 to 24 balls from the peeled potatoes. Rotate the cutter firmly through the flesh so each ball is as round and evenly sized as you can manage. Keep them in cold water while you finish; save the trimmings for soup or mash.

3. 3

   Cook à l'anglaise

   Put the potato balls in a saucepan, cover generously with cold water, and add about two-thirds of the salt. Bring the water slowly to a quiet simmer and cook the potatoes à l'anglaise, plainly in water, for 10 to 14 minutes. They are ready when a small knife enters without resistance but the balls still hold their edges. Drain carefully, cover, and keep warm. If a few begin to split, drain them immediately and let them firm in the dry warmth of the covered pan. Ça se rattrape.

4. 4

   Set the fumet poach

   Season the sole lightly with the remaining salt and lay it presentation side up in a wide buttered fish pan or shallow roasting pan that holds it without bending. Pour the fish fumet around the sole, not over it, and distribute the butter in small pieces across its surface exactly as the source directs. Cover the fish closely with a piece of parchment, then seal the pan with its lid or foil. The shallow liquid and trapped moisture poach the sole together.

5. 5

   Poach at a tremble

   Bake the covered sole for 18 to 25 minutes, depending on its thickness. Check at 18 minutes beside the backbone: the flesh should be opaque, release cleanly from the bone, and reach 145°F (63°C) at its thickest point. The fumet should barely tremble. If it begins bubbling hard, lift the pan from the oven for one minute, lower the heat to 325°F (165°C), and continue gently. A boil tightens delicate sole, so catch it early.

6. 6

   Warm the Normande sauce

   While the sole poaches, warm the prepared Normande sauce over the lowest heat, stirring constantly around the base and corners of the pan. Never let it boil. It is ready when it coats the back of a spoon in a smooth ivory layer. If it becomes greasy or grainy, remove it from the heat and whisk in 1 tablespoon (15 ml / 15 g) of cold heavy cream; repeat once if needed, then pass the sauce through a fine sieve. Ça se rattrape.

7. 7

   Build the Royale

   Empty and dry the warmed platter. Lift the sole from its poaching pan with two broad spatulas, let the excess fumet drain away, and settle the fish in the center. Arrange the four mushrooms, four quenelles, four crayfish tails, and four truffle slices along its length, keeping each garnish distinct. Surround the sole closely with the potato balls, forming an even ring as the source directs.

8. 8

   Coat and serve

   Taste the Normande sauce and correct the salt if necessary. If it has tightened too far, loosen it with a spoonful of the sole's hot poaching liquid. Spoon the sauce generously over the fish and its garnishes, letting it gleam and pool slightly around the sole while the potato ring remains visible. Carry the platter straight to the table. This dish waits for no one. À table!

Chef Tips

• •Ask the fishmonger for one large Dover sole, skinned and trimmed but left whole on the bone. The bone protects the flesh during poaching and gives you a splendid centerpiece; four loose fillets would cook quickly, but they would change the source's presentation and timing.
• •Good frozen cooked crayfish tails are an honest answer when fresh crayfish are unavailable. Thaw them slowly in the cold and blot them dry. Use four intact tails, not a heap of broken meat.
• •Fresh black truffle is deeply seasonal. A good whole preserved black truffle, sliced just before assembly, keeps the intended shape and earthy perfume. Truffle oil does neither and has no place here.
• •The recipe clock begins with prepared Normande sauce and poached fish forcemeat quenelles, because the source treats both as finished components waiting for assembly. Make them separately, then give this final poach your full attention.
• •Pour a dry white Burgundy with enough body for the cream and truffle, but enough acidity for the sole. The dish is rich in detail, so the wine should be composed.

Advance Preparation

• •Poach the fish forcemeat quenelles and cook the mushrooms up to one day ahead. Cool them promptly, cover, and refrigerate; bring them toward room temperature for 30 minutes before assembling the dish.
• •Prepare the Normande sauce earlier the same day, cool it promptly, and refrigerate it covered. Reheat over very low heat while stirring constantly, using the cold cream rescue if the emulsion becomes grainy.
• •Turn the potato balls up to four hours ahead and hold them completely submerged in cold water. Drain them just before cooking à l'anglaise.
• •Have the sole cleaned on the day of serving. The final poaching, saucing, and assembly should happen immediately before the platter goes to the table.
