John Dory (St. Pierre)
John Dory has the delicacy of sole and the firmness of turbot. A light flouring, a quick butter sauté, and nut-brown beurre noisette show exactly why looks never mattered.

Filets de Maquereau au Persil
Created by Chef Juliette
Based on No. 1012, Filets de Maquereau au Persil, from Le Guide Culinaire (1907) by Auguste Escoffier
Mackerel fillets take a quiet parsley poach, shed their skins, and meet a glossy sauce au beurre bright with fresh parsley: one gentle-heat lesson, generous enough for supper.

Filets de Maquereau au Persil (mackerel fillets with parsley) teaches one true thing: gentle heat protects both fish and sauce. The court-bouillon must barely tremble, because boiling tightens the mackerel before its flesh has time to turn tender. The same restraint keeps the sauce au beurre, a butter sauce, glossy rather than grainy. C'est la même grammaire.
The original kitchen assumed someone to raise the fillets, court-bouillon ready by the potful, a saucier to hand over Butter Sauce (No. 66), and a long serving dish waiting at the pass. It required neither a salamander nor a stockpot kept forever on the fire, so we won't invent them. Four prepared skin-on fillets, one wide sauté pan, and a home-scale measure of the finished sauce are the honest equivalents. Raising fish and maintaining station pots were brigade scaffolding; the parsley court-bouillon, skinning after poaching, and fresh parsley folded into the sauce at the last moment are the dish itself, and they stay.
When it is right, the mackerel remains plump beneath an ivory-gold sauce flecked vividly green, with enough sauce pooling around it for potatoes alongside. Watch the liquid once the fish goes in. If it begins to boil, lift the pan from the heat at once; ça se rattrape when you catch it promptly.
Mackerel belongs to the everyday tables of Brittany and Normandy, fed by the Atlantic and Channel landings, but this precise sauced preparation comes from the national classical repertoire rather than one exclusive regional tradition. Professional kitchens carried the abundant coastal fish into bourgeois dining rooms by filleting it, poaching it in court-bouillon, and dressing it with a finished butter sauce. Parsley is not a decorative afterthought here: it perfumes the poaching liquor, then returns freshly chopped in the sauce, giving the dish its structure as well as its name.
The technique, the tradition, and the story behind every dish.

Equipment Needed
- •12-inch (30 cm) wide sauté pan with lid
- •Round of baking parchment sized to the pan
- •Broad slotted fish slice
- •Clean fish-bone tweezers
- •Long warmed oval serving platter
Instructions
- 1
Prepare the fillets
Run a fingertip down the centre of each fillet and pull any remaining pin bones with clean tweezers. Trim only ragged edges and leave the skin in place; it holds the tender flesh together during poaching and comes away afterward, exactly as the original method intends. Keep the fillets cold while you prepare the liquor, and warm a long oval platter for serving.
Ask the fishmonger to raise the fillets but leave their skins on. Buying them prepared removes brigade knife work, not technique. - 2
Infuse the court-bouillon
Combine the white wine, water, parsley leaves, and salt in a wide 12-inch (30 cm) sauté pan. Bring the white-wine court-bouillon just to a simmer, then lower the heat and let the parsley infuse for 8 minutes. The surface should move quietly, with an occasional bubble at the edge, not churn.
- 3
Poach without boiling
Lay the mackerel fillets skin-side down in a single layer among the parsley leaves. Cover the surface with a round of parchment, lower the heat, and poach for 4 to 6 minutes, depending on thickness, until the flesh is opaque at its deepest point and separates into moist flakes under light pressure. An instant-read thermometer should register 145°F (63°C). If the liquor begins to boil, pull the pan from the burner until the surface calms, then return it over lower heat. Ça se rattrape, provided you act before the flesh contracts and splits.

Drain and skin
Lift the fillets carefully with a broad fish slice and let them drain for a few seconds, then set them skin-side up on a tray. Starting at the tail end, catch the skin with a small piece of kitchen paper and peel it away in one slow movement. If a patch clings, spoon a little hot court-bouillon over it, wait 20 seconds, and try again rather than scraping the flesh. Arrange the skinned fillets immediately on the warmed long platter.

Finish the parsley sauce
Warm the Butter Sauce (No. 66) over the gentlest heat until it flows heavily from a spoon, but do not let it boil. Remove it from the heat and fold in the freshly chopped parsley at the last moment so the herb stays green and clear-tasting. If the sauce has tightened, whisk in warm strained court-bouillon one teaspoon at a time; if an oily rim appears, take it off the heat and whisk in one teaspoon of cold water from the centre outward. Ça se rattrape. Cover the fillets generously with the parsley sauce and serve at once. À table!
Chef Tips
- •Fresh mackerel has brilliant skin, clear eyes when bought whole, and flesh that springs back under a finger. Its richness is magnificent, but it does not improve by waiting, so buy it the day you cook it.
- •The 21 g of parsley leaves in three cups of court-bouillon preserves the book's proportion of one-half ounce per pint. Use leaves rather than stems here; stems can turn the short poaching liquor coarse and grassy.
- •Serve with pommes vapeur, plain steamed potatoes, to catch the sauce. Pour the same dry white wine used in the court-bouillon, or a crisp Muscadet from the Loire's Atlantic edge.
Advance Preparation
- •Prepare the Butter Sauce (No. 66) according to its own entry up to 30 minutes before poaching. Hold it in a heatproof bowl over barely warm water, whisking occasionally, and never set it over direct heat.
- •The mackerel can be pin-boned and trimmed up to 4 hours ahead. Keep it covered in the coldest part of the refrigerator, then chop the finishing parsley only when the fish enters the court-bouillon.

Éperlans au Gratin
Tiny smelts, shallot, mushrooms, white wine, gratin sauce, and fine bread raspings meet a fierce oven, where the fish must turn tender in the same breath the buttered crust bronzes.
