Instructions

1. 1

   Sequence the supper

   Bring the prepared Rice à l’Indienne to serving temperature and keep it covered in its own pan. Warm a shallow serving bowl with hot water, then empty and dry it before serving. Measure the velouté and set a fine-mesh sieve over a clean saucepan. Once the kidneys enter the skillet, nothing else should need attention; the sauce may wait, but the kidneys may not.

   Serve the Rice à l’Indienne in a separate bowl, exactly as the original formula directs. Its loose grains receive the sauce without sitting beneath the kidneys and softening their browned edges.
2. 2

   Trim and slice

   Peel away every trace of the thin outer membrane. Split each kidney lengthwise, cut out the firm white core and tubes with the point of a small knife, then slice the lobes crosswise about ½ inch (1.25 cm) thick. Pat the pieces thoroughly dry and keep them cold. Do not season yet, because salt draws moisture to the surface and wet kidneys cannot sauté cleanly.

3. 3

   Build the curry sauce

   Melt 1½ tablespoons (22 ml / 21 g) of the butter in a small saucepan over medium-low heat. Add the onion and cook for 5 to 6 minutes, stirring often, until soft and translucent but not browned. Add the curry powder and stir for 30 seconds, just until fragrant. Pour in the prepared plain light chicken velouté and hold it at a bare simmer for 3 minutes, giving the onion time to season the sauce without reducing it heavily.

4. 4

   Pass the velouté

   Rub the sauce through the fine-mesh sieve into the clean saucepan, pressing firmly on the onion with the back of a spoon. This replaces the brigade’s tammy while preserving the point of the step: curry flavour and onion sweetness remain, coarse pieces do not. Return the sauce to the lowest heat. If passing has made it too tight, loosen it with hot water a teaspoon at a time until it coats a spoon in a thin, glossy layer. Taste and use a little of the measured salt only if the velouté needs it.

5. 5

   Sauté the kidneys

   Season the dry kidney slices with the remaining salt and the pepper. Heat a wide 12-inch (30 cm) skillet over medium-high heat, then add half of the remaining butter. When the foam subsides, lay in half the kidneys with space between them. Sauté for 60 to 90 seconds on the first side and 45 to 60 seconds on the second, until bronze at the edges and just cooked through; repeat with fresh butter and the second batch. The thickest pieces should reach 160°F (71°C). If grey liquid floods the pan, lift the kidneys out immediately, pour away the liquid, wipe and reheat the skillet, then return them briefly in a single layer. Ça se rattrape.

   Crowding is the usual failure. Two quick batches are faster than one crowded batch because the skillet stays hot enough to brown rather than simmer.

   Fold and serve

   Lift the kidneys from the skillet with a slotted spoon and fold them directly into the warm curried velouté. Turn them gently over the lowest heat for no more than 30 seconds, only long enough to coat and unite them with the sauce. Never let it boil; boiling tightens the kidneys into rubber. If a bubble appears, lift the saucepan from the heat and stir. Transfer at once to the warmed serving bowl and bring the Rice à l’Indienne alongside. À table!

Chef Tips

• •Ask a butcher for mutton kidneys first, as the source specifies. When only lamb kidneys are available, buy enough to match the weight; they are smaller and milder, so the number changes but the proportion of kidney to sauce does not.
• •Fresh kidneys smell clean and mineral, never sharply ammoniacal. Keep them very cold, trim them carefully, and skip the fashionable soak. Waterlogged kidneys shed liquid in the skillet, which is precisely what this sauté cannot afford.
• •The velouté is the foundation, not optional decoration. A light chicken velouté is the practical home equivalent to the old kitchen’s ready veal stockpot; cream soup, demi-glace, and cornstarch gravy each change the sauce into something else.
• •Use a fresh, restrained curry powder. À l’Indienne here means a large pinch bloomed in butter, not a heavily spiced stew. The onion, velouté, and kidney must all remain legible.

Advance Preparation

• •The onion-curry velouté can be cooked and passed through the sieve up to two days ahead. Cool it promptly, cover, refrigerate, and reheat over very low heat before sautéing the kidneys.
• •Trim and slice the kidneys up to four hours ahead, then refrigerate them on an absorbent-lined tray under a loose cover. Pat them dry again and season only when the skillet is ready.
• •The kidneys themselves do not improve by waiting. If leftovers remain, chill them promptly for no more than one day and reheat once over gentle heat until they reach 165°F (74°C), accepting that their texture will be firmer.
