Pommes Irène

Pommes Irène (poached apple cases with vanilla-plum ice and kirsched meringue) teaches one thing above all: temperature is an ingredient. The apple must stay tender, the ice must stay frozen, and the Meringue à l’Italienne (No. 2383), Italian meringue, must color before either has time to surrender. Before you touch a pan, clear a level place in the freezer and make certain your broiler is fierce.

The original formula assumed a glacer with prepared vanilla ice, a pâtissier with meringue ready, several hands assembling at once, and a salamander that could bronze the crown in seconds. At home, dense vanilla ice cream replaces the separately churned ice, a metal tray carries four apples from freezer to broiler, and the broiler supplies that sharp top heat. Brigade quantities and separate ice work were scaffolding, so they can go. The one-to-three proportion of cooked plum purée to vanilla ice, the firm poach, the sieved apple pulp, the Kirsch, and the rapid coloring are the dish itself, so they stay. One cook, one stove, one evening.

When it lands correctly, the apple is translucent and tender beneath a caramel-flecked white crown, while the first spoonful opens onto pale rose ice scented with plum, vanilla, and Kirsch. Firm the filled apples thoroughly before the meringue goes on. That cold reserve is what gives you enough time to make the finish magnificent.
