Homard à la Mornay, otherwise au Gratin

Homard à la Mornay, otherwise au Gratin (lobster with Mornay, glazed under fierce heat) teaches the true meaning of gratiner, to glaze and brown quickly. Everything beneath the crust must already be cooked, sauced, and hot before it approaches the broiler. That is the one true thing to know before touching a pan: the fierce heat colors the dish, it must never be asked to reheat it.

The original assumed a saucier on staff, a stock never off the fire for the parent preparations, several pans holding each element hot, and a salamander ready at service. Your kitchen gets one small saucepan of Mornay, the precise shell arrangement of Homard Cardinal (No. 943), and a broiler heated as fiercely as it will go. Separate holding pans and brigade portions are scaffolding, so they go. The mushroom and truffle salpicon, the filled carapaces, the real butter and cheese, and the rapid glaze are the dish, so they stay. One cook, one stove, one evening.

At the table, the shells should be coral-red beneath an ivory sauce bronzed to butter-gold, with lobster and truffle visible where the spoon breaks the crust. Have the filled shells hot and the broiler fully heated before you coat them. That final alignment matters more than any flourish.
