Rognons Sautés Turbigo

Ingredients

Equipment Needed

• •12-inch (30 cm) heavy skillet
• •2-quart (2-liter) wide saucepan
• •Small rimmed broiler tray
• •Instant-read thermometer
• •10-inch (25 cm) round timbale or shallow serving dish

Instructions

1. 1

   Trim the kidneys

   Pull away every trace of the thin outer membrane, split each kidney lengthwise, and cut out the hard white core with the point of a small knife without carving deeply into the lobes. Wipe the halves dry and keep them cold. Do not season yet; salt left sitting on kidney draws moisture to the surface, and moisture prevents the fast brown crust the sauté requires.

   Fresh kidney smells clean and mineral, never sharply of ammonia. Soaking cannot repair stale offal, and a good kidney does not need its character washed away.
2. 2

   Build the half-glaze

   If the chilled stock does not set softly, take 3 tablespoons (45 ml) from it, sprinkle over the optional gelatin, and leave it for 5 minutes. Boil the remaining stock in a wide saucepan until reduced by half to about 1¼ cups (300 ml), then whisk in the tomato purée and bloomed gelatin. Simmer for 4 to 5 minutes, until the sauce naps the back of a spoon and the tomato is distinctly present in both colour and flavour. This is tomatéd, not merely tinted. Season with ½ teaspoon of the salt and ½ teaspoon of the pepper, then whisk in 1 tablespoon of the butter and hold the sauce over the gentlest heat. If it remains thin, reduce it further; if it tightens into a glaze, whisk in hot water one spoonful at a time. Ça se rattrape.

   Grill the chipolatas

   Heat the broiler and set a rack about 4 inches (10 cm) below it. Arrange the chipolatas on a small rimmed tray and broil for 8 to 12 minutes, turning every few minutes, until their skins are evenly bronzed and their centres reach 160°F (71°C). Keep them warm, loosely covered. The old salamander gave fierce overhead heat; the broiler is its honest home equivalent.

4. 4

   Cook the mushrooms

   Melt 1 tablespoon of the butter in a large skillet over medium-high heat. Add the mushrooms in one layer and cook for 6 to 8 minutes, turning as their sides colour, until they are browned, tender, and still round rather than collapsed. Season with ¼ teaspoon salt and ⅛ teaspoon pepper, then transfer them to a warm bowl. Wipe the skillet clean so damp mushroom residue cannot interfere with the kidney sauté.

5. 5

   Sauté the kidneys

   Season the kidney halves at the last moment with the remaining ½ teaspoon salt and ⅜ teaspoon pepper. Heat the clean skillet over high heat until thoroughly hot. Add 2 tablespoons of butter, and when its foam subsides, lay in half the kidneys cut-side down. Cook without moving for about 90 seconds, turn, and brown the rounded sides for another 1 to 2 minutes, rolling them briefly onto any pale edges. Transfer them to a warm plate and repeat with the remaining 2 tablespoons butter and kidneys. They should be deeply browned and just cooked through, reaching 160°F (71°C) at the thickest point, but still yielding under a finger. If the pan floods with grey liquid, lift the kidneys out immediately, pour away the liquid, wipe and reheat the pan, then return them for 30 seconds per side. Ça se rattrape. Leaving them to boil in that liquid does not.

   Do not crowd the skillet. Two swift batches take less time than one crowded batch and preserve the tender texture that defines the dish.

   Build the timbale

   Empty and dry a round serving dish warmed with hot water. Arrange the kidney halves in a close circle around its edge, then pile the whole mushrooms and grilled chipolatas in the middle. Bring the sauce back just to a tremble, taste for the forceful seasoning the entry demands, and pour it over the kidneys and garnish so everything gleams and a little sauce pools beneath. Serve immediately. À table!

Chef Tips

• •Ask a butcher for kidneys from mature sheep, which have the fuller flavour specified by the entry. If only lamb kidneys are available, use 8 small kidneys of roughly the same total weight and shorten the sauté slightly; the result will be milder, but the Turbigo arrangement remains intact.
• •A good brown stock should wobble softly when cold. If yours pours like water, use the optional gelatin before reducing it. Gelatin supplies the body a stockpot once gave the saucier, while reduction supplies the flavour. One cannot replace the other.
• •Choose plain, lightly seasoned chipolatas rather than sausages heavy with herbs, smoke, or chilli. Here chipolata means a small sausage, and its job is to bring browned pork richness without arguing with the kidney or tomatéd sauce.
• •Serve with pommes purée or a broad slice of toasted country bread to catch the sauce. A lively Beaujolais-Villages has enough fruit and acidity for the offal, sausage, and tomato without weighing the plate down.

Advance Preparation

• •The tomatéd half-glaze can be prepared up to 2 days ahead, chilled promptly, and reheated gently. Loosen it with a spoonful of hot water if it sets too firmly.
• •The kidneys may be trimmed up to 6 hours ahead and held covered in the cold on absorbent paper. Dry them again and season only when the skillet is hot.
• •The mushrooms can be cleaned and the chipolatas arranged on their tray earlier in the day, but cook both near serving time. Once sautéed, the kidneys wait for no one.
