Tournedos Péruvienne

Tournedos Péruvienne (grilled beef tenderloin with stuffed oxalis roots) teaches coordination. The garnish needs patience; the tournedos need fierce heat and no waiting. Have the Oxalis cases tender and their duxelles, finely chopped mushrooms cooked nearly dry, ready to bronze before the beef touches the grill. Tenderloin dries while a cook fusses with garnish.

The formula did not call for a saucier on staff or the stockpot kept constantly at the fire. Its hidden luxury was labor: one cook hollowed and baked the roots, another watched the grill, and a salamander supplied fierce top heat at precisely the right moment. At home, one skillet builds the duxelles, a cast-iron grill pan cooks four steaks, and the oven broiler replaces the salamander. Dividing the oven work into a gentle bake and a brief gratin keeps the original intent while letting one cook control the timing. One cook, one stove, one evening.

The separate kitchen stations were brigade scaffolding, so they go. The one-to-one pairing of tournedos and oxalis cases, the mushroom filling enriched with the chopped root, the bread raspings and oil, and the hot, quick grilling are the dish itself, so they stay. The step that decides the plate is simple: finish the cases first, then make the grill pan fiercely hot before the tournedos meet it.
