Cœur de Cardon aux Fines Herbes

Ingredients

Equipment Needed

• •5-quart (4.7-liter) nonreactive pot
• •10-inch (25 cm) wide sauté pan
• •Small wide saucepan
• •Sharp paring knife
• •Kitchen twine
• •Parchment paper

Instructions

1. 1

   Cook the heart tender

   Strip away the tough outer ribs until a compact, pale heart remains, keeping its base intact so the inner ribs stay together. Reserve the outer ribs for another dish. Trim away the leafy tips, pull off only the obvious coarse strings, and tie the heart across its width in two places with kitchen twine. Whisk the flour with 1 cup of the measured cold water in a nonreactive pot until smooth, then add the remaining water, lemon juice, and salt. This is the blanc de cuisson. Add the heart, cover it with a cartouche, a parchment lid, and bring the liquid to a bare simmer. Cook for 45 to 60 minutes, turning once, until a skewer passes through the thickest part without crunching but the heart still holds its shape. If it floats, set a small heatproof plate over the parchment. If it softens too far, lift it out immediately and chill it for 20 minutes before trimming. Ça se rattrape.

   Keep the simmer gentle. Hard boiling knocks the compact heart apart before you can cut the roundels the dish requires.
2. 2

   Reduce the pale glaze

   While the cardoon cooks, reserve ¼ cup of the stock for adjustments. If your stock lacks natural gelatin, sprinkle the powdered gelatin over 1 tablespoon of that cold reserve and leave it to bloom. Bring the remaining stock to a lively simmer in a small wide saucepan and reduce it to about ⅔ cup, roughly 25 to 35 minutes. It should be pale gold and translucent, leaving a light coat on a spoon rather than a dark, sticky syrup. Whisk in the bloomed gelatin, if using, and hold the reduction off the heat. If it becomes too tight or salty, loosen it spoonful by spoonful with the reserved stock. This is the honest home equivalent of the pale meat glaze that once waited beside the saucier.

   Use unsalted stock. Reducing salted stock concentrates every grain, and butter cannot rescue a glaze that already tastes briny.
3. 3

   Shape the roundels

   Lift the tender heart from the blanc and let it drain for 5 minutes, then remove the twine. With a sharp paring knife, trim it evenly all around into a compact cylinder, removing loose fibers and irregular ribs without carving away the tender center. Save the trimmings with the outer ribs. Cut laterally across the cylinder into roundels exactly ⅓ inch, or 8 mm, thick. Pat every surface dry. The cylinder matters because it gives clean, even roundels; lathe-like perfection does not.

4. 4

   Mount and roll

   Warm the reduced glaze over low heat only until it flows freely, then pull the pan from the heat. Whisk in the cold butter a few cubes at a time until the glaze is pale, thin, and glossy. Stir in the parsley, chervil, chives, and tarragon. Add the warm, dry cardoon roundels in a single layer and rock the sauté pan gently, turning each piece with a spoon until every surface wears a translucent coat. Return the pan to the lowest heat for no more than a minute if the roundels need warming, but do not let the glaze boil or brown. If butter beads around the edge, transfer the cardoon to a warm plate and whisk 1 teaspoon of cold reserved stock into the glaze off the heat until smooth, then return the roundels. Ça se rattrape.

   Chop the fines herbes only as the cardoon drains. Their fresh fragrance is part of the finish, and prolonged heat turns both their color and their flavor dull.
5. 5

   Serve at once

   Arrange four or five glazed roundels beside each tournedos or portion of sautéed chicken, or overlap them loosely in a warm shallow serving dish. Spoon every trace of the herb-flecked glaze over them. Serve immediately, while the butter still gleams and the herbs remain green. A mounted glaze waits poorly, and there is no virtue in making it wait. À table!

Chef Tips

• •Cardoon truly wants its cool season. Choose a bunch with broad, firm, pale inner ribs and no hollow or rusty patches. If cardoon cannot be found, artichoke bottoms are its closest cousin, but they make another garnish; celery does not carry the same thistle flavor.
• •The pale glaze needs rich unsalted chicken or white veal stock. Dark beef demi-glace overwhelms the cardoon and stains it brown, while ordinary salted broth becomes harsh as it reduces.
• •Do not discard the outer ribs and cylindrical trimmings. Peel away their strings, cook them in a fresh blanc until tender, and use them in a gratin or vegetable soup.
• •The source gives the proper companions: tournedos and sautéed chicken. Their browned fond supplies the depth that the pale cardoon deliberately lacks, while the fines herbes keep the plate from becoming heavy.

Advance Preparation

• •The cardoon heart can be cooked up to 24 hours ahead. Set the pot in a basin of ice water to stop the cooking, chill the heart in its blanc, and keep it covered. Drain, shape, and dry it shortly before finishing.
• •Reduce the stock up to 48 hours ahead and chill it promptly in a covered container. Reheat it gently, then add the butter and fines herbes only when the cardoon is ready.
• •Do not finish the assembled dish in advance. Once mounted with butter and fresh herbs, the glaze should go directly from the sauté pan to the table.
