Ingredients

Equipment Needed

• •Rimmed baking sheet
• •Small sharp knife
• •Sturdy teaspoon or melon baller
• •2-quart saucepan and whisk
• •Wide 12-inch poaching pan
• •Eight small cups or ramekins
• •Slotted spoon
• •Instant-read thermometer

Instructions

1. 1

   Bake the potatoes

   Heat the oven to 425°F (220°C). Prick the potatoes several times and set them directly on the oven rack with a baking sheet beneath to catch any drips. Bake for 50 to 65 minutes, turning once, until a small knife passes cleanly through the center but the skins remain intact. Let them stand only until your hands can manage them; warm potato is easier to hollow without cracking.

2. 2

   Cream the chicken

   While the potatoes bake, combine the cold ground chicken with ¼ cup (60 ml / 60 g) of the cream, ½ teaspoon of the salt, and ⅛ teaspoon of the white pepper. Stir firmly with a wooden spoon until the mince becomes cohesive and slightly tacky, with no pockets of loose cream. Keep it cold until needed. If it turns slack or greasy, the mixture has become too warm; chill it for 10 minutes, then stir again. Ça se rattrape.

   The chicken must be ground finely enough to spread in a thin, even layer. Coarse mince leaves gaps and cooks into pebbly lumps rather than a tender lining.
3. 3

   Shape the cradles

   Lower the oven to 400°F (200°C). Cut each potato in half lengthwise with the point of a small knife. Scoop out the flesh carefully, leaving a sturdy ½-inch (1.25 cm) wall and an unbroken skin. Melt 1 tablespoon of the butter and brush it inside the eight shells, then season lightly with salt and white pepper. If a shell splits, press a little reserved potato pulp across the tear from inside and brush it with butter. It will hold once baked.

4. 4

   Line with chicken

   Divide the creamed chicken among the shells, about 2 tablespoons in each, and spread it thinly over the bottom and sides to form the cradle's lining. Arrange the shells on a rimmed baking sheet and bake for 15 to 18 minutes, until the chicken is opaque, tender, and reaches 165°F (74°C) at its thickest point. Do not brown it. If the edges color before the center is cooked, cover the tray loosely with foil. Reduce the oven to 325°F (165°C) and hold the cradles there while you finish the sauce and eggs.

5. 5

   Build Sauce Aurore

   Melt 2 tablespoons of the butter in a 2-quart saucepan over medium-low heat. Stir in the flour and cook this roux for 2 minutes, keeping it pale gold. Whisk in the warm chicken stock a little at a time, making each addition smooth before adding the next, then simmer gently for 5 minutes until the velouté naps the back of a spoon. Whisk in the tomato purée and remaining ¼ cup (60 ml / 60 g) cream, then simmer for 3 minutes. Season with salt and white pepper, remove from the heat, and whisk in the final tablespoon of cold butter for gloss. If the sauce is lumpy, whisk firmly and strain it; if too thick, add stock by the spoonful; if thin, simmer it a little longer. Ça se rattrape. Keep it warm without boiling.

6. 6

   Poach the eggs

   Do not begin until the cradles are cooked and the Sauce Aurore is ready. Bring the water and vinegar to a bare tremble in a wide pan, with small bubbles gathering below the surface but no rolling boil. Crack each egg into its own small cup, then slide four eggs into the water one at a time. Nudge any wandering white gently around its yolk and poach for about 3 minutes, until the white is set and the yolk remains yielding. Lift the eggs into a bowl of cold water and repeat with the remaining four. If the whites feather, lower the heat and trim the wisps after poaching. The egg inside is unharmed.

7. 7

   Assemble the berceaux

   Bring a fresh pan of water just below a simmer. Rewarm all eight eggs for 45 to 60 seconds, then lift them onto a clean towel and blot them thoroughly; water left on an egg thins the sauce at once. Set one egg into each hot chicken-lined cradle and spoon over enough Sauce Aurore to coat it generously, letting a little settle around the rim. Do not put the assembled eggs under the broiler. The source asks for a coating, and further heat would toughen the whites.

8. 8

   Serve at once

   Arrange two cradles per person on warmed plates, or carry all eight to the table on an oval platter. Serve immediately, while the potato skins retain their firmness, the sauce still gleams, and the yolks run into the creamed chicken when cut. À table!

Chef Tips

• •The source calls for fine Dutch potatoes, meaning evenly shaped potatoes suitable for baking and hollowing. A long, regular russet is the honest home equivalent: its skin holds, its flesh scoops cleanly, and four large potatoes give eight useful cradles.
• •Use chicken ground from both breast and thigh if you can. Breast keeps the mince pale, while a little thigh gives it enough fat to remain tender after baking. Technique first, always.
• •Sauce Aurore should be coral-ivory, not red. Tomato supports the velouté with color and acidity; it doesn't replace it. If the sauce tastes chiefly of tomato, loosen it with a little more stock and cream.
• •The removed potato flesh is not part of this preparation. Save it for a purée, thicken a soup with it, or season it and brown it in butter the next morning.
• •For a dinner party, pour a dry Champagne or another brisk French sparkling wine. Its acidity cuts through the cream and butter without bullying the egg.

Advance Preparation

• •The potatoes can be baked, hollowed, lined with chicken, and cooked up to one day ahead. Cover and chill them, then reheat at 350°F (175°C) for 10 to 12 minutes before assembling.
• •The Sauce Aurore can be prepared one day ahead and chilled with parchment pressed against its surface. Reheat it slowly, whisking in a spoonful of stock if it has tightened.
• •The eggs can be poached up to 2 hours ahead and held submerged in cold water in the refrigerator. Rewarm them for 45 to 60 seconds in water just below a simmer, then dry them thoroughly before saucing.
• •Do not store the dish fully assembled. The potato softens under the sauce and the egg continues to firm, so keep the cradles, eggs, and Sauce Aurore separate until serving.
