A signature dish from the kitchens of Lyon, these delicate fish dumplings are pillowy-light and poached until tender, then served in a rich, velvety crayfish cream sauce. The contrast between the airy dumpling and the deeply flavored shellfish sauce makes this a true French bistro classic.

Ingredients

For the panade (flour paste base)

• 250 ml whole milk
• 40 g unsalted butter
• 60 g all-purpose flour
• 1/4 tsp fine salt

For the fish dumplings

• 500 g pike fillet (or pike-perch), skinless and boneless
• 2 large egg whites
• 80 ml heavy cream, well chilled
• 1/2 tsp fine salt
• 1/4 tsp white pepper
• Pinch of freshly grated nutmeg

For Sauce Nantua

• 400 g live crayfish (or 200 g cooked crayfish tails with shells reserved)
• 1 small shallot, finely diced
• 1 tbsp tomato paste
• 50 ml cognac
• 150 ml dry white wine
• 300 ml fish stock
• 200 ml heavy cream
• 40 g unsalted butter, cold and cubed
• Pinch of cayenne pepper
• Salt to taste

For the poaching liquid

• 1 L water
• 50 ml white wine
• 1 bay leaf
• 5 whole black peppercorns

Directions

1. Make the panade: in a saucepan bring milk and butter to a boil, add flour and salt all at once, and stir vigorously over medium heat for 2 to 3 minutes until it forms a smooth ball that leaves the sides of the pan. Transfer to a bowl, spread slightly, and let cool to room temperature.
2. Prepare the fish paste: cut pike into chunks and pulse in a chilled food processor, scraping often, until a very smooth paste forms. With the motor running, slowly pour in the cold cream. For the silkiest texture, press the puree through a fine-mesh sieve into a bowl set over ice.
3. Combine the fish paste with the cooled panade and mix well. Beat in the egg whites one at a time until fully incorporated, then season with salt, white pepper, and nutmeg. Cover and chill the mixture for at least 1 hour to firm up.
4. Prepare the crayfish sauce: if using live crayfish, blanch in salted boiling water for 2 minutes, then drain and pick the tails and claws, reserving the shells. Melt half the butter in a saucepan, sweat the shallot until soft, add the reserved shells, and crush them with a wooden spoon to release flavor. Stir in tomato paste and cook for 2 minutes.
5. Deglaze with cognac and let it reduce by half, then add the white wine and reduce by another half. Pour in the fish stock and simmer gently for 20 minutes. Strain through a fine sieve, pressing on the shells, then return the liquid to the pan.
6. Whisk the cream into the strained liquid and reduce until the sauce lightly coats the back of a spoon. Whisk in the remaining cold butter, add the crayfish tails to warm through, and season with cayenne and salt. Keep warm.
7. Poach the dumplings: bring the poaching liquid to a gentle simmer in a wide pan. Using two spoons dipped in hot water, shape oval dumplings from the chilled fish mixture and slide them carefully into the liquid.
8. Poach for 6 to 8 minutes, turning gently once, until the dumplings are firm, puffed, and cooked through. Lift out with a slotted spoon and drain briefly on a clean kitchen towel.
9. To serve, spoon a generous pool of crayfish sauce onto warm plates, place 2 dumplings per person on the sauce, and garnish with the reserved crayfish claws and a small sprig of chervil or flat-leaf parsley.

Cook’s Notes

• Chilling the fish paste thoroughly is essential, well-chilled paste holds its shape and poaches into airy, tender dumplings.
• If live crayfish are hard to find, substitute langoustines or prawns and build the sauce with their shells for the same depth of flavor.
• Cook the panade fully, otherwise the dumplings will feel heavy and doughy rather than light and custard-like.
• Test one dumpling before poaching the entire batch to check seasoning, shape, and timing in your pan.
• The dumplings can be shaped and poached up to 2 hours ahead, then gently rewarmed in the sauce just before serving.
