Potato Croquettes
Dry the purée until it becomes a paste, bind it with yolks, then crumb à l'anglaise and fry: crisp golden croquettes with a tender center that hold their shape in hot fat.

Duchesse Potatoes
Created by Chef Juliette
Pommes Duchesse teach the discipline of a dry purée: enrich it with butter and yolks, shape it neatly, then gild and streak each piece before baking it deep gold.

Pommes Duchesse (Duchess potatoes) teach one true thing: control the water and the potato will obey you. A dry purée holds its shape, takes butter and yolks without slumping, and bakes into tender little loaves with bronzed edges. A wet one spreads. Drying the potatoes thoroughly is the step that decides the dish.
The old entry assumed croquette potato mixture already waiting, a floured board, and enough trained hands to shape trays for service. It calls for an oven, not a sauce or stockpot, and although a brigade might keep a salamander ready for rapid browning, your honest equivalent is a parchment-lined tray in a thoroughly heated home oven. I have reduced the production batch to four generous servings. The brigade quantities were scaffolding; the dry purée, yolks, gilding, and protective streaks are the dish, so every one remains.
When they are right, the centres are soft and buttery while the scored crowns are burnished gold. Shape them while the mixture is warm enough to cooperate, then gild lightly and cut the streaks through the beaten egg. Those little vents matter: they keep the gilding close to the potato instead of letting it rise in blisters.
Pommes Duchesse belong to the French classical garniture tradition of the grand urban kitchen, where shaped potato preparations framed roasts, cutlets, and sauced dishes without competing with them. The piped rosette became the most familiar form, but classical entries also shaped the mixture by hand into cottage loaves, shuttles, quoits, lozenges, and rectangles on a floured board. Their name suggests ceremony, yet their method is practical home cooking: dry potato, enrichment, careful shaping, and a brief bake.
The technique, the tradition, and the story behind every dish.

Equipment Needed

- •Wide saucepan and flexible spatula
- •Large parchment-lined baking sheet
- •Small pastry brush
- •Small sharp knife or palette knives
Instructions
- 1
Bake the potatoes
Heat the oven to 425°F (220°C) with a rack in the middle. Prick the potatoes and bake them directly on the rack for 45 to 55 minutes, until a skewer passes through without resistance. Baking instead of boiling keeps excess water out of the purée, which gives the yolks and butter a firm foundation. Line a baking sheet with parchment while the potatoes cook.

Rice and dry
Split the potatoes while they are hot, scoop out the flesh, and pass it through a potato ricer or food mill into a wide saucepan. Set the pan over low heat and turn the purée with a flexible spatula for 2 to 3 minutes, until it looks matte, leaves the sides cleanly, and gives off no visible moisture. Don't beat it with a food processor or blender; ruptured starch makes glue, and no quantity of butter can persuade glue to become potato again.
No ricer? Press the hot flesh through a fine-mesh sieve with a sturdy spoon. It takes a little muscle, but produces the smooth texture the shapes require. - 3
Enrich the purée
Take the pan off the heat. Work in the butter until fully absorbed, then season with the salt and white pepper. Add the yolks one at a time, mixing each in completely before the next; the purée should be smooth, rich, and firm enough to hold a peak. If it turns slack, don't add handfuls of flour. Ça se rattrape: spread it on a cool tray and chill it for 10 to 15 minutes, then test a spoonful. Cooling firms the butter and starch without making the potatoes heavy.

Shape the potatoes
Lower the oven to 400°F (200°C). Dust the board very lightly with the flour and divide the warm mixture into 12 equal portions. With floured fingertips or two small palette knives, form diminutive cottage loaves, shuttle-shaped loaves, thick lozenges, rectangles, or quoits with a small opening in the centre. Transfer them to the lined baking sheet, leaving space between them, and brush away loose flour. Handle them decisively but gently; overworking compacts the purée.
- 5
Gild and streak
Brush each shape with a thin, even coat of beaten egg. This is to gild: the book's term for covering the surface with beaten egg so heat gives it a golden sheen. For quoits, rectangles, and lozenges, draw shallow parallel or crossing streaks through the wet gilding with the tip of a small knife. The cuts vent the surface and prevent the egg coating from blistering. If egg gathers in the cuts or around the base, lift the excess with a dry corner of the brush before baking.
A heavy egg coating sets like a separate skin. Beat the egg until no strings remain, load the brush sparingly, and gild twice only if the first coat looks bare. - 6
Bake until golden
Bake for 10 to 14 minutes, rotating the tray once, until the potatoes are heated through and the raised edges are a deep butter gold. If a patch of gilding begins to blister, prick it immediately with the knife tip and return the tray to the oven for another minute; it will settle. Slide the Pommes Duchesse onto a warm serving platter and bring them straight to the table. À table!
Chef Tips
- •Choose a floury potato. Russet and Maris Piper dry readily and break into a light purée; waxy potatoes keep their structure too stubbornly and make the mixture dense.
- •The source entry shapes the mixture by hand rather than requiring a piping bag. If you prefer the familiar rosette, a large open-star tip will work, but the little loaves, quoits, and lozenges preserve this entry's method and show the gilded streaks beautifully.
- •Flour belongs on the board, not inside the potato. Use only enough to prevent sticking, then brush away the excess before gilding so the egg adheres evenly.
- •Serve these beside roast chicken, beef, lamb, or a cutlet with a properly reduced sauce. Their ridges catch the juices, which is precisely why this handsome little garnish earned its place.
Advance Preparation
- •Prepare and shape the potatoes up to one day ahead. Refrigerate them on the lined tray under a loose cover, then gild and streak them immediately before baking.
- •The enriched purée can be made several hours ahead and chilled. Let it stand at room temperature for about 15 minutes before shaping so the butter softens enough for clean work.
- •Finished Pommes Duchesse are best from the oven. If necessary, reheat them at 375°F (190°C) for 6 to 8 minutes, just until the centres are hot and the gilding regains its sheen.

Dauphine Potatoes
Pommes dauphine marry dry potato croquette paste with savory pâte à choux, then seal the small cylinders à l’anglaise and fry them gold. The lesson is moisture control: dry paste puffs, wet paste escapes.

Marquise Potatoes
Croquette paste meets a fierce tomato reduction, then pipes into ridged meringue shapes and takes an egg gilding. Keep the purée dry, and every proud little Marquise holds its crown.

Ordinary or Dry Duxelle
Duxelles ordinaire turns mushroom stalks and parings into a concentrated classical base through one uncompromising act: press them dry, then cook until every drop is gone and only butter-glossed mushroom remains.
