Crêtes et Rognons de Coq

Crêtes et rognons de coq (cocks’ combs and kidneys) teach blanchiment, the careful whitening of delicate ingredients without toughening them. The principle is simple and absolute: the first water warms only enough to loosen the skins. Never let that water boil.

The original entry assumed a garde-manger with several basins constantly refreshed and gallons of blanc ready for the day’s garnishes. A saucier, a stockpot never off the fire, and a salamander belonged to the composed dishes that followed, not to this preparation itself. That is brigade scaffolding, so it can go. Two bowls, one saucepan, and two quarts of the referenced cooking liquor give four people the same result, one cook, one stove, one evening. The cold soaking, skinning, whitening, and late addition of the rognons must stay because they are the dish.

When they are right, the crêtes are ivory and gently resilient, with no ragged skin clinging to their folds; the rognons remain plump and tender rather than tightened into little pellets. Before you touch the pan, remember the step that decides everything: warm the skin-loosening bath slowly, drain the crêtes the instant it becomes lukewarm, and rub while the skins are ready to slip.
