Filet de Bœuf Lorette

Filet de Bœuf Lorette (beef fillet butter-roasted with Lorette potato crescents and asparagus) teaches one thing before you touch a pan: grand service is timing made visible. The fillet must be rested yet hot, the asparagus glossed at the last breath, the Pommes de Terre Lorette (No. 2226) crisp enough to stand in two pyramids, and the sauce warm but still apart. None is difficult alone. They must arrive together.

The book's kitchen assumed a larding needle, a saucier on staff, stock never off the fire, a fry cook waiting beside very hot fat, and a salamander fierce enough to glaze the beef in moments. Your honest equivalents are a narrow boning knife, prepared veal demi-glace, Poëlings (No. 250) scaled to one fillet, a heavy lidded casserole, and the broiler already hot. The brigade staffing is scaffolding and goes. The larding, butter poëling, made-to-order frying, paired pyramids, butter-bound asparagus, last glaze, and sauce served apart are the dish and stay. One cook, one stove, one evening.

Do the quiet work first: shape and chill the potatoes, trim the asparagus, build the tomatéd half-glaze, and warm the platter. Then the final minutes become assembly rather than panic. The one step that decides the whole presentation is the fry: drop the potato crescents only while the rested fillet is waiting to be glazed.
