Butters and Creams
Beurres et crèmes d’hors-d’œuvre prove that cold-table finesse is mostly timing: smooth good dairy, cover it closely, hold it cool, then season only as you dish so every spoonful keeps a clean edge.

Nantua Duchesses
Created by Chef Juliette
Petite Choux hide a rose crayfish purée beneath layer after layer of clear gelée. The lesson is temperature and patience: each transparent film must set before the next one goes on.

Duchesses Nantua (little crayfish-filled Choux) teach the discipline of glazing with gelée, savory aspic: every coat must be cool, thin, and fully set before the next touches it. One heavy pour makes a rubber casing; warm gelée soaks the shell and slips away. Temperature is the one true thing to settle before you touch a pan.
The old entry assumed a garde-manger, the cold-larder cook, beside a saucier, a stockpot never off the fire, ready gelée, and trays of Choux. A salamander has no work here; this is a cold preparation. At home, one small saucepan, a food processor, clear prepared fish stock strengthened with powdered gelatin, and a refrigerator shelf do the same work for twenty-four pieces. Ready aspic and brigade quantities are scaffolding, so they go. The repeated glazing is the dish, so it stays. One cook, one stove, one evening.
Inside, the purée should taste unmistakably of crayfish, rich with butter and softly pink, not whipped into an airy mousse. Outside, the finished gelée should gleam as a barely visible film. Chill the filled Choux completely before the first spoonful, then give every coat its time in the cold.
Nantua is a town in Ain, east of Lyon, where Lac de Nantua and nearby waterways made écrevisses central to the local table and gave the classical word Nantua its precise meaning: a preparation marked by crayfish. Duchesses Nantua belong to the grand-kitchen garde-manger rather than to Nantua's household repertoire, so the name records the rosy filling, not a local pastry custom. Repeated clear gelée glazing carried the filled Choux into formal cold hors d'oeuvre service beneath a polished protective film.
The technique, the tradition, and the story behind every dish.

Equipment Needed
- •1-quart (1-liter) saucepan
- •Food processor
- •Fine-mesh sieve
- •Piping bag with a ⅜-inch (1-cm) plain tip
- •Wire rack set over a rimmed quarter-sheet pan
- •Small offset spatula
Instructions
- 1
Prepare the gelée
Pour ¼ cup (60 ml) of the cold fish stock into a small bowl and sprinkle the gelatin evenly over it. Leave it undisturbed for 5 minutes, until every grain has swollen. Heat the remaining 1¾ cups (415 ml) of stock with ¼ teaspoon of the salt until hot but never boiling, then remove it from the heat and stir in the bloomed gelatin until completely dissolved. Strain through a dampened fine cloth or a very fine sieve into a shallow bowl. Chill for at least 1 hour, until fully set.
A cloudy stock makes a cloudy glaze. If your stock is not clear, strain it through a damp coffee filter before adding the gelatin. - 2
Make the crayfish purée
Press the crayfish meat between clean towels until no surface moisture remains. Process it to a fine paste, scraping down the bowl several times. Add the butter in three portions, then the remaining ½ teaspoon salt, white pepper, and cayenne. Pulse in the cold cream a spoonful at a time, stopping as soon as the purée is smooth, rosy, and firm enough to hold a soft peak. Force it through a fine-mesh sieve. If the butter turns oily because the mixture has warmed, spread the purée in a shallow dish, chill it for 10 minutes, and beat it briefly until smooth again.

Open the Choux
Turn each finished Choux over and cut a neat opening about ⅜ inch (1 cm) wide in its base. Pull out only any damp web of pastry blocking the cavity; leave the crisp walls intact. The shells must feel dry and feather-light. If they have softened, refresh them for 5 minutes in a 325°F (160°C) oven, then cool them completely before filling.

Fill and chill
Transfer the crayfish purée to a piping bag fitted with a ⅜-inch (1 cm) plain tip. Pipe it into each Choux until the shell feels pleasantly weighted and the filling reaches the opening, but stop before the shell strains or cracks. Wipe the bases clean, arrange the Choux opening-side down on a chilled tray, and refrigerate them uncovered for 20 minutes. Their surfaces must be cold and dry before glazing.

Melt the gelée cold
Stand the bowl of set gelée over warm water and stir just until it becomes liquid, then remove it immediately. Let it cool to 65 to 68°F (18 to 20°C), when it runs from a spoon like light syrup but still feels cool. If solid pieces remain, warm it for a few seconds more; if it flows like water, chill it for 5 minutes. This cold-melted consistency lets the gelée cling without soaking the Choux.
- 6
Build the clear film
Set the chilled Choux on a wire rack over a cold rimmed tray. Using a teaspoon, sprinkle a scant spoonful of gelée over each crown and let it flow naturally down the sides. Refrigerate for 8 to 10 minutes, until the first film no longer feels tacky, then repeat for 4 to 6 coats. If the gelée slides off, either it or the Choux is too warm. Ça se rattrape: chill both for 10 minutes and resume. If the gelée thickens in the bowl, loosen it over warm water rather than laying on one heavy coat. The final film should be even, transparent, and almost too thin to see.

Set and serve
Chill the finished Duchesses for 30 minutes so the last coat sets firmly. Lift them from the rack with a small offset spatula and arrange them on a chilled platter without garnish; the butter-gold Choux, rose filling, and clear film are the whole presentation. Serve within 6 hours, while the shells still retain some delicacy. À table!
Chef Tips
- •Crayfish is the name and the flavor. Frozen cooked tail meat is the honest home answer when live crayfish are unavailable, but thaw it slowly in the refrigerator and press it very dry. Shrimp makes a pleasant filled Choux, but it does not make Duchesses Nantua.
- •Gelée must taste slightly more seasoned while liquid than seems necessary, because chilling quiets salt. Taste the warm stock before adding the gelatin and adjust only if your stock needs it.
- •A thermometer is useful but not essential. Properly cooled gelée feels cool against the lip and falls from the spoon in a narrow, slightly thick ribbon. Warm gelée runs away; gelée that is too cold lands in lumps.
- •Serve with a dry white wine from Bugey, close to Nantua, whose freshness suits both the crayfish and the cold gelée without overwhelming them.
Advance Preparation
- •The gelée can be prepared and refrigerated, covered, up to 2 days ahead. Melt only the amount needed for glazing and keep the rest cold.
- •The crayfish purée can be made up to 1 day ahead. Press food-safe wrap directly against its surface and refrigerate it promptly.
- •The finished Choux may be held airtight for 1 day and refreshed briefly in the oven if needed. Fill and glaze the Duchesses 2 to 6 hours before serving, not overnight, because the purée eventually softens the shells.

Anchovy Butter
Beurre d’Anchois turns two ingredients into a silky, deeply savoury spread. Pounding makes them one, but the fine sieve finishes the work, removing every fibre and pin bone before the butter reaches bread.

Caviare Butter
Beurre de caviar turns two ingredients into a polished cold-table spread: keep the butter cool, pound until completely uniform, then pass it fine so every bite carries the roe's full salt-brine.

Shrimp Butter
Whole shell-on shrimp, equal butter, and two patient passes make a rose-pink beurre de crevettes with remarkable delicacy: a small classical preparation whose silk depends entirely on the second straining.
