Filets de Soles aux Huîtres

Ingredients

Equipment Needed

• •Oyster knife and thick folded kitchen towel or oyster glove
• •10 to 12-inch (25 to 30 cm) lidded sauté pan
• •Fine-mesh sieve lined with a damp coffee filter
• •Small heavy-bottomed saucepan
• •Flexible fish spatula or slotted spoon
• •Instant-read thermometer
• •Warm oval serving platter

Instructions

1. 1

   Warm the sauce

   Warm 1¼ cups of the prepared Sauce Normande over the lowest heat, stirring often, until it flows readily from a spoon. Keep the remaining ¼ cup cool for adjustment. Do not let the warm sauce simmer; Sauce Normande is already finished, and hard heat can separate its butter and cream. Fill the serving platter with hot water so the porcelain loses its chill, then empty and dry it just before plating.

2. 2

   Open and strain

   Discard any oyster that remains open when tapped. Hold each oyster cup-side down in a thick folded towel, open it with an oyster knife, and collect every drop of liquor in a bowl. Slide each oyster free and inspect it for shell fragments. Line a fine-mesh sieve with a damp coffee filter and strain the liquor into a wide sauté pan; the filter is the honest home equivalent of the linen named in the original.

   Work over the bowl, not the sink. The oyster liquor is part of the sauce, and losing it means losing the dish's clearest flavor.
3. 3

   Poach the oysters

   Set the pan of strained liquor over gentle heat and add the oysters. Let the liquid come only to a quiet tremble, turning the oysters once, until they look plump and opaque, their edges begin to curl, and their centers reach 145°F / 63°C, about 1 to 2 minutes depending on size. Lift them out with a slotted spoon and cover loosely. Trim away any tough ragged fringe, the beard named in the classical instruction, and remove any last speck of shell. Keep every drop of liquor in the pan.

4. 4

   Fold and poach

   Fold each sole fillet neatly into thirds, with the smoother side facing outward and the final fold underneath. Arrange the fillets in one close layer in the oyster liquor and dot them with the butter, using all of it. Cover the fish directly with a round of parchment, then hold the liquid at the barest tremble until the fillets turn opaque, feel resilient under a fingertip, and reach 145°F / 63°C at their thickest point, about 5 to 7 minutes. A hard boil tightens sole and clouds the liquor; if the pan begins to bubble strongly, pull it from the heat for thirty seconds. Ça se rattrape.

5. 5

   Reduce the liquor

   Lift the sole carefully onto a warm tray, letting its juices drain back into the pan, and cover it loosely. Strain the cooking liquor into a small clean saucepan and reduce it at a controlled simmer until about ⅓ cup (80 ml / about 85 g) remains and the taste is distinctly of oysters but still rounded by butter. Taste twice as it reduces. If the salt turns sharp, stop immediately; salt does not cook away, it only concentrates, and the reserved Sauce Normande will provide the adjustment.

6. 6

   Finish the Normande

   Off the heat, whisk the reduced cooking liquor gradually into the warm Sauce Normande, tasting as you go. Add the cool reserved sauce if the oyster liquor needs softening, then return the pan to the lowest heat only long enough for the sauce to nappe, coating the back of a spoon in an even ivory layer. Never boil it. If the sauce looks greasy or finely curdled, put the cold water in a clean bowl and whisk in one spoonful of broken sauce until smooth, then rebuild the rest spoonful by spoonful. Ça se rattrape.

7. 7

   Arrange and coat

   Arrange the eight folded fillets in an overlapping oval on the warmed platter. Place the twelve oysters in the center, three for each serving, exactly as the source directs. Spoon the finished Sauce Normande generously over both fish and oysters, covering every surface without flooding the rim. Serve at once while the sole is tender and the sauce holds its gloss. À table!

Chef Tips

• •Ask the fishmonger to skin four whole soles and cut eight tidy fillets. True Dover sole has the fine, firm texture this gentle poach rewards. If it is unavailable, lemon sole or thin flounder can take the technique honestly, though the flavor and texture will be different.
• •The oysters must smell clean and briny, never strong. Store them cup-side down under a damp towel in the cold, and open them only when the sauce and pan are ready.
• •Sauce Normande is a finished component in this entry, just as the book treats it. Prepare it from its own recipe rather than improvising a cream sauce, and season it lightly because the reduced oyster liquor supplies the final salt.
• •Use unsalted butter. Oyster liquor varies wildly in salinity, and salted butter takes away your room to reduce it properly. We don't apologize for butter, but we do control the salt.
• •Serve with small boiled potatoes or buttered spinach, something quiet that will collect the sauce without competing. A dry Norman cider or a mineral white wine suits the oysters and cream.

Advance Preparation

• •Prepare the Sauce Normande earlier the same day, or up to one day ahead if its own recipe permits. Chill it promptly, then rewarm it over very gentle heat while keeping ¼ cup cool for adjustment.
• •The sole may be trimmed, checked for bones, and refrigerated between sheets of parchment for up to 6 hours. Fold it only shortly before poaching so the fillets retain their clean shape.
• •Scrub and inspect the oysters earlier in the day, but do not open them until cooking begins. Their liquor is freshest and cleanest when it goes directly from shell to filter.
