Pommes de Terre Mirette

Pommes de Terre Mirette (creamy butter-cooked potato julienne with truffle and meat glaze) teaches that the cut governs the cooking. Before a pan is touched, know this: every potato rod must be about 1/8 inch (3 mm) square, because fine, even julienne softens together and stays creamy, while mixed sizes give you raw cores beside mash.

The original formula assumed a saucier on staff, a stock never off the fire to become glace de viande (meat glaze), and a salamander waiting to color the top in moments. At home, a true prepared glace de viande and a hot broiler are the honest equivalents. The day-long reduction and brigade holding are scaffolding and can go; the exact julienne, the source ratio of two ounces of truffle and three tablespoons of glaze to one pound of potato, gentle butter cooking, and the swift Parmesan finish are the dish and must stay.

The book already gives its working proportions per pound, so one pound becomes four generous side servings. Because it leaves the butter and Parmesan to professional judgment, this home version fixes only those amounts, enough to coat and glaze without swamping the potatoes. One cook, one stove, one evening. The whole recipe turns on the knife work: cut the julienne evenly before the butter ever warms.
