Cardons à la Mornay

Cardons à la Mornay (cardoons glazed with cheese-enriched béchamel) teaches the difference between cooking and glazing. The cardoon must be completely tender, well drained, and still hot before the sauce touches it; the broiler will bronze the Mornay, but it won't soften a stubborn rib. That is the one true thing to carry to the stove.

The source is brigade shorthand: keep the same pyramid, replace the demi-glace (half-glaze sauce) with Mornay Sauce, glaze quickly, and send it. It assumed a vegetable station with cooked cardoons ready, a saucier on staff, a stockpot and demi-glace never far from the fire for related preparations, and a salamander fierce enough to color sauce in moments. Here, one bunch feeds four, the stock and demi-glace leave because this entry expressly replaces them, the saucier's finished Mornay Sauce is warmed in one small pan, and a fully heated household broiler stands in for the salamander. Bundling brigade quantities and holding them for service was scaffolding, so it goes. The tender simmer, low pyramid, Mornay coat, and immediate glaze are the dish, so they stay. One cook, one stove, one evening.

When it lands, pale cardoon ribs sit beneath an ivory sauce mottled butter-gold at the crown, with a faint artichoke bitterness against the cheese. Mornay left under heat can split, so the final relay must be continuous: sauce, coat, broiler, table. Have the broiler fully hot before you warm the sauce; that is the step that decides the gratin.
