Cardoons (Cardons)

Cardons au blanc (cardoons cooked in a pale flour-and-lemon court-bouillon) teach one true thing before you touch the pan: air is the enemy. A peeled stalk oxidizes with astonishing speed, so each clean piece must meet lemon and acidulated water at once. Keep it pale first, then make it tender.

The original kitchen mixed the Special Court-bouillon, or Blanc (No. 167) in a five-quart batch and protected the broad surface with a pound of chopped veal fat. For four servings, two quarts of Blanc and 180 grams of fat preserve that proportion; a snug saucepan and a cartouche (parchment lid) give the home cook the same shelter from air. The great volume was brigade scaffolding. The acidulated hold, the Blanc, and the protective fat are the dish, so they stay. One cook, one stove, one evening.

When they are ready, the cardons are ivory-pale, gently lemony, and tender enough for a knife to enter without force, but still whole enough to lift into the serving dish. There is no browning to hide careless preparation. Have the acidulated water waiting before you make the first cut.
