Truite à la Cambacérès
Whole trout becomes a generous celebration dish: crayfish Mousseline held inside, truffle and carrot stitched across its flank, Sauternes beneath, and crayfish-butter Béchamel served from the side.

Truite Saumonée (Salmon Trout)
Created by Chef Juliette
Based on No. 811, Truite Saumonée (Salmon Trout), from Le Guide Culinaire (1907) by Auguste Escoffier
A whole salmon trout, butter-gold at the edges and moist along the bone, with white-wine pan juices mounted with cold butter. The lesson is proportion: smaller than salmon, it belongs whole at the table.

Truite Saumonée (salmon trout) teaches proportion before technique: this fish is smaller than salmon, so leave it whole. A darne is a thick cross-cut steak through the bone, sensible for a large salmon and wasteful here. Once you understand that size decides the cut, the rest is calm cooking.
The source entry gives no sauce, flavourings, or cooking formula because it stands as a gateway to the preparations that follow. Its professional kitchen could reach for a fish kettle, a stock never off the fire, a saucier, and a salamander whenever the chosen preparation required them. For one cook, one stove, one evening, I add a neutral classical frame: a hot oven cooks the whole fish evenly, while its white-wine roasting juices reduce in one small pan and become a butter emulsion. The brigade equipment is scaffolding and can go. Serving this smaller fish whole is the intent, and that stays.
The one step that matters is judging the flesh beside the backbone, not trusting the clock. Take the fish out while it is still moist and let the short rest finish the cooking; butter can rescue a lean sauce, but it cannot put moisture back into an overcooked trout.
Truite saumonée belongs to French fish-market language and to the river and lake tables of the Jura, Savoy, and Dauphiné, although no single region owns it. The name does not identify a salmon-trout hybrid or one fixed species; saumonée describes trout whose flesh has taken on a salmon colour, traditionally through a crustacean-rich diet and now often through carefully controlled feed. Because these trout generally reached the kitchen smaller than salmon, French cooks served them whole and reserved the darne, a cross-cut steak through the bone, for the larger fish.
The technique, the tradition, and the story behind every dish.

Equipment Needed
- •Large rimmed metal roasting pan, about 18 by 13 inches
- •Instant-read thermometer
- •Small heavy saucepan, about 1 quart
- •Two broad fish spatulas or sturdy turners
- •Warm oval serving platter
Instructions
- 1
Ready the whole fish
Heat the oven to 450°F (230°C) with a rack in the centre. Run a fingertip against the grain of the skin and scrape away any scales the fishmonger missed, then rinse the cavity briefly and dry the fish thoroughly, inside and out. Season with the salt and white pepper, including the cavity. Fill the cavity loosely with the parsley sprigs and lemon slices; don't pack it tightly, or the thickest flesh will cook too slowly.
A dry surface takes on colour and holds the butter. Pay particular attention behind the head, along the belly opening, and beneath the fins, where water likes to hide. - 2
Arrange and butter
Spread the sliced shallots down the centre of a large rimmed metal roasting pan and lay the fish over them. Rub the softened butter over both sides of the trout, leaving the upper side facing up. Pour ½ cup (120 ml / 120 g) of the wine around the fish, not over it, so the butter remains on the skin. The shallots lift the fish from the bare metal and perfume the juices without becoming a separate garnish.

Roast by temperature
Roast for 20 minutes, then test through the thickest part behind the head, aiming the thermometer toward the backbone without touching bone. Continue for 3 to 8 minutes as needed, until the flesh reaches 140°F (60°C), looks just opaque beside the spine, and separates under light pressure. If the tail colours too quickly, cover only that thin end with a small piece of foil. Transfer the fish carefully to a warm oval platter and rest it for 5 to 8 minutes; verify that the thickest flesh reaches 145°F (63°C). If it doesn't, return the platter to the oven for 2 minutes and test again.

Reduce the pan juices
While the trout rests, scrape the shallots and every drop of roasting juice into a small heavy saucepan. Add the remaining ¼ cup (60 ml / 60 g) wine and the juice from the reserved lemon half. Boil briskly until the liquid reduces to about 3 tablespoons and tastes concentrated but not harsh, 3 to 5 minutes. If the roasting pan went dry, deglaze it with 1 tablespoon of the cold water and scrape up the butter-gold film before reducing. Ça se rattrape.

Mount the butter
Take the saucepan off the heat. Make a beurre monté, a warm butter emulsion, by whisking in the cold butter a few cubes at a time, adding more only when the previous butter has disappeared. Return the pan to the lowest heat for a few seconds only if the butter refuses to soften; the sauce must never boil after mounting. If it separates into greasy streaks, put 1 teaspoon cold water in a clean pan and whisk the broken sauce into it gradually. Ça se rattrape. Taste and adjust the salt, pepper, and lemon.

Sauce and carve
Remove the spent parsley sprigs and lemon slices from the cavity. Spoon a little beurre monté around the fish, leaving the burnished skin visible, and finish with the chopped parsley. Present the trout whole. To serve, cut behind the head and along the top of the backbone, then lift the upper fillet away in generous portions. Remove the exposed skeleton from tail to head and serve the lower fillet. Pass the remaining sauce at the table. À table!
Chef Tips
- •Truite saumonée is a market description, not a dependable species name. Ask for a whole salmon-coloured trout in the stated weight range, with bright convex eyes, red gills, firm flesh, and a clean smell. Technique first, always, but freshness is the beginning of fish cookery.
- •The source explicitly permits salmon in place of salmon trout. Choose a small whole salmon of the same cleaned weight and follow the thermometer rather than the clock. A very large salmon belongs in darnes or fillets, because the whole-service proportion is the point here.
- •Use a dry white wine with clean acidity and little oak. A Jacquère from Savoy is a lovely regional companion, but any honest dry white that tastes good in the glass will make a sound reduction.
- •Cold butter and restrained heat decide the beurre monté. Butter, not margarine. A substitute cannot form the same supple emulsion and brings no pleasure to the sauce.
- •Refrigerate leftover trout within 2 hours and eat it within 2 days. Serve it cool with the remaining sauce allowed to soften at room temperature; reheating a carved trout usually takes more from it than it gives.
Advance Preparation
- •Have the fishmonger scale, gut, and remove the gills. Up to 6 hours before dinner, check the fish for stray scales, dry it thoroughly, and refrigerate it uncovered on a tray. Season only when the oven is heating.
- •Slice the shallots, prepare the lemon and parsley, cube the cold butter, and measure the wine up to 4 hours ahead. Keep the herbs and butter covered in the refrigerator.
- •Roast the fish as guests sit down. The beurre monté is a last-minute sauce and should be made during the trout's short rest; once mounted, keep it beside the stove rather than over direct heat.

Truites Saumonées Froides
Cold-poached salmon trout, rebuilt over tomato mousse and lacquered with clear fish aspic, makes a splendid buffet centerpiece. Its secret is simple: fish, mousse, and glaze must be thoroughly cold.

Préparation de la Mousse de Tomates
Tomato cooked into butter, steadied with velouté and gelatine, then lightened with cream whipped only halfway: a savoury bavarois whose silken texture depends on stopping the whisk before peaks appear.

Other Preparations of Trout after the same Recipe
Nine cold trout variations from one classical grammar: a gentle poach, reduced liquor, velouté, and cream set into a silken mousse, then finished with the garnish that names each version.
