Instructions

1. 1

   Prepare the elements

   Heat the oven to 325°F (165°C) with a rack in the middle. Butter a 13 by 9-inch (33 by 23 cm) shallow ovenproof dish with 1 tablespoon of the butter. Pat the sole dry, season both sides with ¾ teaspoon of the salt and half the white pepper, then arrange the fillets in one layer, overlapping only their tapered ends. Make the concassée (peeled, seeded, finely chopped tomato): score the tomatoes, lower them into boiling water for 20 seconds, cool them, peel, halve, and remove the seeds. Press the halves cut-side down on a clean towel before dicing. This pressing is not cosmetic; loose tomato juice would turn the garnish into a stew.

   If a fillet has a very thin tail, fold the last inch underneath itself. An even thickness gives the sole a fair chance of finishing at the same moment.

   Cook the garnish

   Melt 1½ tablespoons of butter in a 10-inch (25 cm) skillet over medium heat. Add the minced mushrooms and ¼ teaspoon salt, then cook for 6 to 8 minutes, stirring often, until their water has evaporated and they smell deeply savory. Transfer them to a bowl. Melt another 1½ tablespoons of butter in the skillet, add the concassée, and cook for 4 to 6 minutes, until glossy but nearly dry. Return the mushrooms, fold in the chives, and keep the garnish warm. If liquid gathers beneath it, keep cooking uncovered until it disappears; flour does not belong here.

3. 3

   Poach the sole

   Warm the white wine and fish fumet together just to a bare tremble, then pour them around the sole, not directly over it. Lay a sheet of parchment on the surface and poach in the oven for 6 to 9 minutes. The liquid should barely move. The fillets are ready when their centers have turned opaque and the thickest one reaches 135 to 140°F (57 to 60°C); the final glaze will carry them safely to 145°F (63°C). Lift the sole onto the center of a broiler-safe platter in four overlapping pairs and cover loosely with parchment. Strain and save every drop of the poaching liquid.

4. 4

   Build the sauce

   While the fish poaches, melt 1 tablespoon butter in a 2-quart (2 L) saucepan. Whisk in the flour and cook for about 90 seconds without letting the roux color, then take it off the heat. Strain the cuisson, the poaching liquor, into the wiped garnish skillet and boil briskly until reduced to ¾ cup (180 ml). Whisk the hot cuisson gradually into the roux, return the saucepan to gentle heat, and simmer for 3 minutes. It should coat a spoon lightly, not sit on it like paste. If the sauce has lumps, pass it through the fine sieve and carry on.

5. 5

   Finish sauce au vin blanc

   Whisk the cream and egg yolk together in a bowl, then temper them with one-third of the hot sauce. Return everything to the saucepan and whisk over very low heat until the sauce is nappé, thick enough to coat the back of a spoon, about 1 to 2 minutes. Never let it boil. Remove from the heat and whisk in the remaining 5 tablespoons of cold butter, one small piece at a time. If the sauce turns grainy or oily, stop. Ça se rattrape: put 1 tablespoon cold water in a clean bowl, whisk in a spoonful of sauce until smooth, then add the rest gradually. Loosen an over-thick sauce with more cold water, a teaspoon at a time, and season with the remaining salt and white pepper.

6. 6

   Arrange and glaze

   Heat the broiler to high and set its rack 5 to 6 inches (13 to 15 cm) below the element. Rewarm the garnish if necessary, then spoon it in a generous ring around the sole, leaving a narrow clean border between fish and garnish. Nap the fillets with the sauce au vin blanc, stopping precisely at their edges. If sauce falls onto the garnish, wipe it away and replace that small patch before glazing. Broil for 45 to 75 seconds, watching without interruption, until the sauce gleams and takes a few pale-gold freckles. This must be quick; deep browning means dry sole.

7. 7

   Finish and serve

   As the platter leaves the broiler, scatter the chopped parsley over the tomato and mushroom garnish only. Carry the Sole Portugaise straight to the table while the sauce is glossy and the garnish remains distinct. À table!

Chef Tips

• •True Dover sole is ideal because its fine flesh cooks quickly and stays supple beneath the sauce. Lemon sole or petrale sole accepts the method honestly when Dover sole is unavailable, though the flavor differs; avoid thick cod or haddock, which changes both the timing and the character of the plate.
• •Out of tomato season, use 1 cup (240 ml / 220 g) well-drained whole peeled canned tomatoes. Remove the seeds, squeeze the flesh dry, and chop it. The classical pantry solved poor winter tomatoes long ago, and an honest preserved tomato is better than a pale fresh one.
• •Use unsalted fumet. The cuisson reduces hard, and a fully seasoned stock can become briny before it gains enough body. Taste only after the butter has gone in, because butter softens acidity and changes how the salt registers.
• •Choose a broad, broiler-safe metal platter and confirm that it fits beneath the broiler before cooking. Serve with the same dry white wine used in the poach, a Muscadet or restrained Chablis suits the fish without bullying the tomato.
• •Sole Portugaise is best served immediately. Refrigerate leftovers within 2 hours and use them within 1 day; rewarm gently in a covered low oven, since another broiling would dry the fish and split the sauce.

Advance Preparation

• •The tomato and mushroom garnish can be cooked up to 3 hours ahead. Cool and refrigerate it promptly, then rewarm gently and fold in the chives shortly before assembly.
• •The sole can be checked for bones, patted dry, and arranged in its buttered dish up to 4 hours ahead. Cover and refrigerate it, then season immediately before poaching.
• •Do not mount the sauce with yolk and butter in advance. For a dinner party, have every ingredient measured and the platter beside the stove; allow about 20 uninterrupted minutes from poaching the fish to carrying it to the table.
