Ingredients

  • 2 tablespoons chopped anchovy fillets in oil, drained
  • 1 shallot, minced
  • 2 tablespoons red wine vinegar
  • 1 stick unsalted butter, at room temperature
  • 1/4 cup equal parts chopped parsley, tarragon and chives
  • 1/2 teaspoon coarsely ground pepper
  • 2 tablespoons canola oil
  • 12 to 16 ounces top roundsliced crosswise into 4 slices, each slice pounded to a 1/4-inch thickness
  • Montreal steak spice, for seasoning (see Note)

Method

  • In a skillet, combine the anchovies, shallot and vinegar.
  • Cook over moderate heat, stirring, until the anchovies break down and the vinegar has evaporated, about 5 minutes.
  • Mash the anchovies with a wooden spoon.
  • Transfer the mixture to a small bowl and let cool to room temperature.
  • Add the butter, herbs and pepper and mix well.
  • Scrape the butter onto a sheet of parchment paper and roll into a log or pack into an airtight container.
  • In a large cast-iron skillet, heat the canola oil until smoking.
  • Season the steaks on both sides with the Montreal steak spice.
  • Working in 2 batches, sear the steaks over high heat for 30 to 40 seconds per side until well browned outside but rare.
  • Transfer the steaks to a rack set over a baking sheet.
  • On a serving plate, stack the steak slices with a big pat of the anchovy butter between each slice.
  • Top with a big pat of butter and serve immediately, dividing the stack at the table.
