Provided by Martha Stewart

Number Of Ingredients 9

2 tablespoons whole black peppercorns
2 tablespoons dried whole green peppercorns
2 tablespoons Szechuan peppercorns
2 tablespoons whole coriander seeds
4 boneless New York strip (shell) steaks (about 6 ounces each; 1/2 inch thick), room temperature
Coarse salt
3 tablespoons extra-virgin olive oil
1/2 cup balsamic vinegar
1 ounce (2 tablespoons) unsalted butter

Steps:

Preheat oven to 400 degrees. Crush peppercorns and coriander with a mortar and pestle, or with the bottom of a heavy skillet. Spread onto a large dish or a baking sheet.
Season steaks with salt, and coat both sides with ground peppercorn mixture by patting into flesh. Heat oil in an ovenproof skillet (preferably cast-iron) over medium-high heat. Sear steaks until golden brown, about 2 minutes per side. Transfer skillet to oven, and cook steaks about 6 minutes, for medium-rare.
Remove steaks from skillet, and let rest for 10 minutes, reserving juices. Meanwhile, wipe out skillet. Add vinegar, and cook until reduced by half, about 5 minutes. Swirl in reserved steak juices, and the butter. Slice steaks, and serve with sauce.
