Ingredients

  • 2 porterhouse steaks (about 1 1/2 pounds each), cut 1 inch thick
  • 2 tablespoons vegetable oil
  • 1 tablespoon ketchup
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon paprika, preferably sweet Hungarian
  • 1/2 teaspoon dry mustard
  • 2 teaspoons cider vinegar
  • 3 medium cloves garlic, pushed through a garlic press
  • Salt and freshly ground black pepper, to taste
  • 8 tablespoons (1 stick) unsalted butter, chilled, cut into 8 pieces

Method

  • Pat the steaks dry.
  • Lightly coat both steaks with oil and set aside at room temperature for 30 minutes.
  • Combine the ketchup, Worcestershire, paprika, mustard, and vinegar in a medium-size heavy skillet and whisk to blend.
  • Place the skillet on a turned-off burner.
  • Put the garlic in a small dish and cover with plastic wrap.
  • (The recipe may be prepared ahead to this point.)
  • Preheat the broiler.
  • Broil the steaks until seared and well-crusted on one side, about 5 minutes.
  • Turn the steaks, season with salt and pepper, and broil 3 minutes more for rare or 4 minutes more for medium.
  • Transfer the steaks to a cutting board and let rest for 5 minutes.
  • While the steaks are cooking, warm the ketchup mixture over very low heat.
  • When the steaks are resting, add the butter to the warm sauce, 1 or 2 pieces at a time, whisking constantly.
  • The butter should melt but not liquefy.
  • If it is melting too fast, remove the pan from the heat and continue to whisk.
  • Once all the butter has been incorporated, stir in the garlic and season with salt.
  • Carve the steaks into 1/2-inch-thick slices and divide among 4 to 6 warm plates.
  • Spoon 2 tablespoons of the sauce over each portion and serve immediately.
