Filets de Soles Caprice

Filets de Soles Caprice

Created by Chef Juliette

Based on No. 868, Filets de Soles Caprice, from Le Guide Culinaire (1907) by Auguste Escoffier

Filets de Soles Caprice turns restraint into surprise: fine-crumbed sole grilled light gold, buttered banana laid over each fillet, and mustard-bright Sauce Robert sent separately so every bite balances sweet, savory, and sharp.

Filets de Soles Caprice (sole fillets with buttered banana and Sauce Robert) teaches disciplined contrast. Sweet fruit alone would make the fish seem timid, and mustard sauce alone would overwhelm it; tasted together, with the sauce offered separately, they become deliberate. The one true thing to know before touching a pan is this: the crumb coating and the thin sole must finish at the same moment.

The original kitchen assumed a saucier on staff, stock never off the fire, and a salamander whose fierce overhead heat could be judged by eye. At home, prepare the Sauce Robert through its own method ahead of time, warm it gently, and use a low broiler with the tray set well below the element. That is the honest equivalent. The recipe is scaled to eight fillets for four people, one cook, one stove, one evening.

The brigade's separate sauce station and last-second salamander choreography are scaffolding, so they can go. The butter dip, fine fresh crumbs, knife-marked surface, gentle grilling, banana cooked in butter, and Sauce Robert served apart are the dish itself, so every one stays. Watch the color of the crumbs above all: light brown means the fish beneath is still tender.

Filets de Soles Caprice belongs to the cosmopolitan grand-kitchen repertoire of Paris rather than to a provincial larder; in classical naming, Caprice signals a deliberate fancy, here the unlikely meeting of banana and mustard-sharp Sauce Robert. The preparation carries familiar crumbed, salamander-grilled sole into formal service by pairing it with imported sweet fruit and a sauce grounded in onion, wine, and mustard. Its oddity is disciplined rather than random, because the sauce is sent separately and the diner controls the sweet-sharp balance.

Equipment Needed

  • Heavy rimmed sheet pan, about 13 by 18 inches (33 by 46 cm)
  • Wide shallow dish for buttering the fillets
  • Table knife with a broad flat blade and rounded back
  • 12-inch (30 cm) skillet
  • 1-quart (1-liter) saucepan
  • Wide fish spatula
  • Oval serving platter and sauceboat

Instructions

  1. 1

    Ready the service

    Set an oven rack 7 inches (18 cm) below the broiler and heat the broiler on low. Line a heavy rimmed sheet pan with foil and butter it lightly. Warm the Sauce Robert over the gentlest heat until it is fluid and nearly simmering, then cover it and set it off the heat. Do not finish it with butter yet. Warm an oval serving platter and a sauceboat with hot water, then dry them thoroughly just before serving.

  2. 2

    Season the butter

    Reserve 2 tablespoons (30 ml / 28 g) butter in small cold cubes for the Sauce Robert and 2 tablespoons (30 ml / 28 g) for the bananas. Melt the remaining 6 tablespoons (90 ml / 86 g), then stir in the salt and white pepper. Pour two-thirds of this seasoned butter into a shallow dish for coating the fish; keep the rest melted for sprinkling over the crumbs.

  3. 3

    Crumb and mark

    Dry the sole fillets thoroughly. Dip each one in the seasoned melted butter, let the excess fall away, then turn it in the fine fresh bread crumbs. Lay the fillets on the prepared pan without touching. Pat the crumbs gently with the flat of a table knife, then use the rounded back of the knife to mark a shallow criss-cross pattern without cutting into the fish. If a bare patch appears, brush it with a little melted butter and press on fresh crumbs. Ça se rattrape.

  4. 4

    Brown the bananas

    Peel the bananas only now and halve them lengthwise. Melt their reserved 2 tablespoons (30 ml / 28 g) butter in a wide skillet over medium-low heat. When the butter foams, lay in the banana halves cut-side down and cook for 1 to 2 minutes per side, just until butter-gold and glossy while still firm enough to lift. Use two spatulas if they feel fragile. If a half splits, place the broken side against the fish when serving; the flavor has lost nothing. Hold the bananas in the skillet off the heat.

  5. 5

    Grill the sole gently

    Spoon the remaining seasoned melted butter evenly over the crumbed fillets. Slide the pan beneath the low broiler and cook for 4 to 6 minutes, rotating the pan once, until the coating is an even light brown and the flesh is opaque and separates under gentle pressure. The thickest part should reach 145°F (63°C). Fish and coating must finish together. If the crumbs color too quickly, lower the pan and switch off the broiler, letting the hot oven finish the fish; if the fish is ready while the crumbs remain pale, take it out anyway. Pale crumbs can be forgiven. Dry sole cannot.

  6. 6

    Finish Sauce Robert

    Return the Sauce Robert to low heat just until fully warm, then remove it from the burner. Whisk in the reserved cold butter a few cubes at a time, adding each only after the last has disappeared. The sauce should turn glossy and lightly nap the back of a spoon. Never boil it after the butter goes in. If an oily ring appears, stop adding butter and whisk in the cold water a teaspoon at a time until the emulsion closes again. Ça se rattrape. Taste, then pour the sauce into the warm sauceboat.

  7. 7

    Crown and serve

    Transfer the sole to the warm platter in four pairs. If needed, return the bananas to low heat for 30 seconds, then lay one butter-cooked half lengthwise over every fillet. Send the Sauce Robert separately, exactly as the dish requires. Do not pour it over in the kitchen: each diner must meet the sweet banana and mustard-sharp sauce in the proportion they choose. À table!

Chef Tips

  • True Dover sole gives the finest, firmest fillets, but good lemon sole or flounder can carry the method honestly. Ask for evenly sized skinless fillets, because one thick piece among seven thin ones makes gentle grilling needlessly troublesome.
  • Make the crumbs from fresh white bread with the crusts removed, then pulse them fine without turning them to paste. Dried crumbs make a hard shell, and coarse crumbs hide the knife pattern that identifies this preparation.
  • Choose bananas that are fully yellow and fragrant but still firm, with no soft black patches. A green banana tastes chalky; an overripe one collapses in the butter before it reaches the fish.
  • The Sauce Robert must be lively with mustard, not harsh. Serve a dry Loire Chenin Blanc with enough acidity to meet the sauce and enough breadth for the banana and butter.
  • This dish is best the moment it is assembled. If leftovers are unavoidable, chill the fish and sauce separately within 2 hours; reheat the fillets briefly in a moderate oven and warm the sauce gently, whisking in a few drops of water if it has tightened.

Advance Preparation

  • Prepare the Sauce Robert according to its own entry up to 2 days ahead, but leave out the final butter. Cool it promptly, cover, and refrigerate; reheat gently and finish with cold butter only when the fish is ready.
  • Make the fine fresh bread crumbs earlier the same day and keep them covered in the refrigerator so they remain soft rather than drying into grit.
  • The sole may be trimmed, checked for bones, and dried up to 4 hours ahead. Keep it covered and cold, but coat it no more than 15 minutes before broiling. Peel and cook the bananas at the last moment.
