How to cook deliciously - Chef John's Steak Diane
1. Stage
Season steaks generously on both sides with salt. Allow steaks to come to room temperature while you make the sauce.
2. Stage
Stir together demi-glace (see Cook's Note), mustard, Worcestershire sauce, tomato paste, and cayenne pepper in a bowl.
3. Stage
Heat oil in a skillet over very high heat, swirling carefully to evenly cover surface. When oil reaches a smoking point, transfer steaks to oil; add a few chunks of butter. Sear meat on high heat until brown on each side, 2 to 3 minutes per side; keep them on the rare side. An instant-read thermometer inserted into the center should read 125 degrees F (52 degrees C). Transfer steaks to a warm plate.
4. Stage
Stir shallots into skillet; cook until softened, 2 to 3 minutes. Remove skillet from heat; pour in Cognac. Carefully ignite with a fireplace lighter. When alcohol burns off and flames go out, return skillet to high heat and bring to a boil; cook, stirring, a few minutes to reduce slightly. Add demi-glace mixture, cream, and any accumulated juices from the steak. Cook on high heat just until sauce starts to thicken, 3 to 5 minutes. Transfer steaks back to pan and reduce heat to low. Gently simmer until meat is heated through and cooked to your desired level of doneness.
5. Stage
Transfer to hot plates and serve with a generous spoonful or two of sauce. Sprinkle with chives. Chef John
